America is today in the midst of a great technological revolution. With the advent of the silicon chip, information processing, communications, and the national economy have been strikingly altered. The new technology is changing how we live, how we work, how we think. The revolution didn't just happen; it was engineered by a small number of people, principally Middle Americans, whose horizons were as unlimited as the Iowa sky. collectively, they engineered Tomorrow. Foremost among them is Robert Noyce.

The Tinkerings of Robert Noyce
How the Sun Rose on the Silicon Valley, Part 1
In 1948 there were seven thousand people in Grinnell, Iowa, including more than one who didn't dare take a drink in his own house without pulling the shades down first. It was against the law to sell liquor in Grinnell, but it was perfectly legal to drink it at home. So it wasn't that. It wasn't even that someone might look in through the window and disapprove. God knew Grinnell had more than its share of White Ribbon teetotalers, but by 1948 alcohol was hardly the mark of Cain it had once been. No, those timid souls with their fingers through the shade loops inside the white frame houses on Main Street and Park Street were thinking of something else altogether.
They happened to live on land originally owned by the Congregational minister who had founded the town in 1854, Josiah Grinnell. Josiah Grinnell had sold off lots with covenants, in perpetuity, stating that anyone who allowed alcohol to be drunk on his property forfeited ownership. In perpetuity! In perpetuity was forever, and 1948 was not even a hundred years later. In 1948 there were people walking around Grinnell who had known Josiah Grinnell personally. They were getting old; Grinnell had died in 1891; but they were still walking around. So... why take a chance!
The plain truth was, Grinnell had Middle West written all over it. It was squarely in the middle of Iowa's Midland corn belt, where people on the farms said "crawdad" instead of crayfish and "barn lot" instead of barnyard. Grinnell had been one of many Protestant religious communities established in the mid-nineteenth century after Iowa became a state and settlers from the East headed for the farmlands. The streets were lined with white clapboard houses and elm trees, like a New England village. And today, in 1948, the hard-scrubbed Octagon Soap smell of nineteenth century Protestantism still permeated the houses and Main Street as well. That was no small part of what people in the East thought of when they heard the term "Middle West. " For thirty years writers such as Sherwood Anderson, Sinclair Lewis, and Carl Van Vechten had been prompting the most delicious sniggers with their portraits of the churchy, narrow minded Middle West. The Iowa painter Grant Wood was thinking of farms like the ones around Grinnell when he did his famous painting American Gothic. Easterners recognized the grim, juiceless couple in Wood's picture right away. There were John Calvin's and John Knox's rectitude reigning in the sticks.
In the fall of 1948 Harry Truman picked out Grinnell as one of the stops on his whistle-stop campaign tour, one of the hamlets where he could reach out to the little people, the average Americans of the heartland, the people untouched by the sophisticated opinion-makers of New York and Washington. Speaking from the rear platform of his railroad car, Truman said he would never forget Grinnell, because it was Grinnell College, the little Congregational academy over on Park Street, that had given him his first honorary degree. The President's fond recollection didn't cut much ice, as it turned out. The town had voted Republican in every presidential election since the first time Abraham Lincoln ran, in 1860, and wasn't about to change for Harry Truman.
On the face of it, there you had Grinnell Iowa, in 1948: a piece of mid-nineteenth century American history frozen solid in the middle of the twentieth. It was one of the last towns in America that people back east would have figured to become the starting point of a bolt into the future that would create the very substructure, the electronic grid, of life in the year 2000 and beyond.
On the other hand, it wouldn't have surprised Josiah Grinnell in the slightest.
It was in the summer of 1948 that Grant Gale, a forty-five-year-old physics professor at Grinnell College, ran across an item in the newspaper concerning a former classmate of his at the University of Wisconsin named John Bardeen. Bardeen's father had been dean of medicine at Wisconsin, and Gale's wife Harriet's father had been dean of the engineering school, and so Bardeen and Harriet had grown up as fellow faculty brats, as the phrase went. Both Gale and Bardeen had majored in electrical engineering. Eventually Bardeen had taught physics at the University of Minnesota and had then left the academic world to work for Bell Laboratories, the telephone company's main research center, in Murray Hill, New Jersey. And now, according to the item, Bardeen and another engineer at Bell, Walter Brattain, had invented a novel little device they called a transistor.
It was only an item, however: the invention of the transistor in 1948 did not create headlines. The transistor apparently performed the same function as the vacuum tube, which was an essential component of telephone relay systems and radios. Like the vacuum tube, the transistor could isolate a specific electrical signal, such as a radio wave, and amplify it. But the transistor did not require glass tubing, a vacuum, a plate, or a cathode. It was nothing more than two minute gold wires leading to a piece of processed germanium less than a sixteenth of an inch long. Germanium, an element found in coal, was an insulator, not a conductor. But if the germanium was contaminated with impurities, it became a "semiconductor." A vacuum tube was also a semiconductor; the vacuum itself, like the germanium, was an insulator. But as every owner of a portable radio knew, vacuum tubes drew a lot of current, required a warm-up interval before they would work, and then got very hot. A transistor eliminated all these problems and, on top of that, was about fifty times smaller than a vacuum tube.
So far, however, it was impossible to mass-produce transistors, partly because the gold wires had to be made by hand and attached by hand two thousandths of an inch apart. But that was the telephone company's problem. Grant Gale wasn't interested in any present or future applications of the transistor in terms of products. He hoped the transistor might offer a way to study the flow of electrons through a solid (the germanium), a subject physicists had speculated about for decades. He thought it would be terrific to get some transistors for his physics department at Grinnell. So he wrote to Bardeen at Bell Laboratories. Just to make sure his request didn't get lost in the shuffle, he also wrote to the president of Bell Laboratories, Oliver Buckley. Buckley was from Sloane, Iowa, and happened to be a Grinnell graduate. So by the fall of 1948 Gale had obtained two of the first transistors ever made, and he presented the first academic instruction in solid-state electronics available anywhere in the world, for the benefit of the eighteen students majoring in physics at Grinnell College.
One of Grant Gale's senior physics majors was a local boy named Robert Noyce, whom Gale had known for years. Bob and his brothers, Donald, Gaylord, and Ralph, lived just down Park Street and used to rake leaves, mow the lawn, baby-sit, and do other chores for the Gales. Lately Grant Gale had done more than his share of agonizing over Bob Noyce. Like his brothers, Bob was a bright student, but he had just been thrown out of school for a semester, and it had taken every bit of credit Gale had in the local favor bank, not only with other faculty members but also with the sheriff, to keep the boy from being expelled for good and stigmatized with a felony conviction.
Bob Noyce's father, Ralph Sr. was a Congregational minister. Not only that, both of his grandfathers were Congregational ministers. But that hadn't helped at all. In an odd way, after the thing happened, the boy's clerical lineage had boomeranged on him. People were going around saying, "Well, what do you expect from a preacher's son?" It was as if people in Grinnell unconsciously agreed with Sherwood Anderson that underneath the righteousness the midwestern Protestant preachers urged upon them, and which they themselves professed to uphold, lived demons of weakness, perversion, and hypocrisy that would break loose sooner or later.
No one denied that the Noyce boys were polite and proper in all outward appearances. They were all members of the Boy Scouts. They went to Sunday School and the main Sunday service at the First Congregational Church and were active in the church youth groups. They were pumped full of Congregationalism until it was spilling over. Their father, although a minister, was not the minister of the First Congregational Church. He was the associate superintendent of the Iowa Conference of Congregational Churches, whose headquarters were at the college. The original purpose of the college had been to provide a good academic Congregational education, and many of the graduates became teachers. The Conference was a coordinating council rather than a governing body, since a prime tenet of the Congregational Church embedded in its name, was that each congregation was autonomous. Congregationalists rejected the very idea of a church hierarchy. A Congregational minister was not supposed to be a father or even a shepherd, but, rather, a teacher. Each member of the congregation was supposed to internalize the moral precepts of the church and be his own priest dealing directly with God. So the job of secretary of the Iowa Conference of Congregational Churches was anything but a position of power. It didn't pay much, either.
The Noyces didn't own their own house. They lived in a two-story white clapboard house that was owned by the church at Park Street and Tenth Avenue, at the college.
Not having your own house didn't carry the social onus in Grinnell that it did in the East. There was no upper crust in Grinnell. There were no top people who kept the social score in such matters. Congregationalists rejected the idea of a social hierarchy as fiercely as they did the idea of a religious hierarchy. The Congregationalists, like the Presbyterians, Methodists, Baptists, and United Brethren, were Dissenting Protestants. They were direct offshoots of the Separatists, who had split off from the Church of England in the sixteenth and seventeenth centuries and settled New England. At bottom, their doctrine of the autonomous congregation was derived from their hatred of the British system of class and status, with its endless gradations, topped off by the Court and the aristocracy. Even as late as 1948 the typical small town of the Middle West, like Grinnell, had nothing approaching a country club set. There were subtle differences in status in Grinnell, as in any other place, and it was better to be rich than poor, but there were only two obvious social ranks: those who were devout, educated, and hardworking, and those who weren't. Genteel poverty did not doom one socially in Grinnell. Ostentation did. The Noyce boys worked at odd jobs to earn their pocket money. That was socially correct as well as useful. To have devoted the same time to taking tennis lessons or riding lessons would have been a gaffe in Grinnell.
Donald, the oldest of the four boys, had done brilliantly at the college and had just received his Ph.D. in chemistry at Columbia University and was about to join the faculty of the University of California at Berkeley. Gaylord, the second oldest, was teaching school in Turkey. Bob, who was a year younger than Gaylord, had done so well in science at Grinnell High School that Grant Gale had invited him to take the freshman physics course at the college during his high school senior year. He became one of Gale's star students and most tireless laboratory workers from that time on. Despite his apparent passion for the scientific grind, Bob Noyce turned out to be that much-vaunted creature, the well-rounded student. He was a trim, muscular boy, five feet eight, with thick dark brown hair, a strong jawline, and a long, broad nose that gave him a rugged appearance. He was the star diver on the college swimming team and won the Midwest Conference championship in 1947. He sang in choral groups, played the oboe, and was an actor with the college dramatic society. He also acted in a radio drama workshop at the college, along with his friend Peter Hackes and some others who were interested in broadcasting, and was the leading man in a soap opera that was broadcast over station WOI in Ames, Iowa.
Perhaps Bob Noyce was a bit too well rounded for local tastes. There were people who still remembered the business with the box kite back in 1941, when he was thirteen. It had been harmless, but it could have been a disaster. Bob had come across some plans for the building of a box kite, a kite that could carry a person aloft, in the magazine Popular Science. So he and Gaylord made a frame of cross-braced pine and covered it with a bolt of muslin. They tried to get the thing up by running across a field and towing it with a rope, but that didn't work terribly well. Then they hauled it up on the roof of a barn, and Bob sat in the seat and Gaylord ran across the roof, pulling the kite. and Bob was lucky he didn't break his neck when he and the thing hit the ground. So then they tied it to the rear bumper of a neighbor's car. With the neighbor at the wheel, Bob rode the kite and managed to get about twelve feet off the ground and glide for thirty seconds or so and come down without wrecking himself or any citizen's house or livestock.
Livestock. . . yes. Livestock was a major capital asset in Grinnell, and livestock was at the heart of what happened in 1948. In May a group of Bob Noyce's friends in one of the dormitory houses at Grinnell decided to have a luau, and he was in on the planning. The Second World War had popularized the exotic ways of the South Pacific, so that in 1948 the luau was an up-to-the-minute social innovation. The centerpiece of a luau was a whole roasted suckling pig with an apple or a pineapple in its mouth. Bob Noyce, being strong and quick, was one of the two boys assigned to procure the pig. That night they sneaked onto a farm just outside of Grinnell and wrestled a twenty-five-pound suckling out of the pigpen and arrived back at the luau to great applause. Within a few hours the pig was crackling hot and had an apple in its mouth and looked good enough for seconds and thirds, which everybody helped himself to, and there was more applause. The next morning came the moral hangover. The two boys decided to go see the farmer, confess, and pay for the pig. They didn't quite understand how a college luau, starring his pig, would score on the laugh meter with a farmer in midland Iowa. In the state of Iowa, where the vast majority of people depended upon agriculture for a livelihood and upon Protestant morality for their standards, not even stealing a watermelon worth thirty-five cents was likely to be written off as a boyish prank. Stealing a pig was larceny. The farmer got the sheriff and insisted on bringing criminal charges. There was only so much that Ralph Noyce, the preacher with the preacher's son, could do. Grant Gale, on the other hand, was the calm, well-respected third party. He had two difficult tasks: to keep Bob out of jail and out of court and to keep the college administration from expelling him. There was never any hope at all of a mere slap on the wrist. The compromise Grant Gale helped work out? a one-semester suspension? was the best deal Bob could have hoped for realistically.
The Night of the Luau Pig was quite a little scandal on the Grinnell Richter scale. So Gale was all the more impressed by the way Bob Noyce took it. The local death-ray glowers never broke his confidence. All the Noyce boys had a profound and, to tell the truth, baffling confidence. Bob had a certain way of listening and staring. He would lower his head slightly and look up with a gaze that seemed to be about one hundred amperes. While he looked at you he never blinked and never swallowed. He absorbed everything you said and then answered very levelly in a soft baritone voice and often with a smile that showed off his terrific set of teeth. The stare, the voice, the smile; it was all a bit like the movie persona of the most famous of all Grinnell College's alumni, Gary Cooper. With his strong face, his athlete's build, and the Gary Cooper manner, Bob Noyce projected what psychologists call the halo effect. People with the halo effect seem to know exactly what they're doing and, moreover, make you want to admire them for it. They make you see the halos over their heads.
Years later people would naturally wonder where Bob Noyce got his confidence. Many came to the conclusion it was as, much from his mother, Harriett Norton Noyce, as from his father. She was a latter-day version of the sort of strong-willed, intelligent, New England-style woman who had made such a difference during Iowa's pioneer days a hundred years before. His mother and father, with the help of Rowland Cross, who taught mathematics at Grinnell, arranged for Bob to take a job in the actuarial department of Equitable Life in New York City for the summer. He stayed on at the job during the fall semester, then came back to Grinnell at Christmas and rejoined the senior class in January as the second semester began. Gale was impressed by the aplomb with which the prodigal returned. In his first three years Bob had accumulated so many extra credits, it would take him only this final semester to graduate. He resumed college life, including the extracurricular activities, without skipping a beat. But more than that, Gale was gratified by the way Bob became involved with the new experimental device that was absorbing so much of Gale's own time: the transistor.
Bob was not the only physics major interested in the transistor, but he was the one who seemed most curious about where this novel mechanism might lead. He went off to the Massachusetts Institute of Technology, in Cambridge, in the fall to begin his graduate work. When he brought up the subject of the transistor at MIT, even to faculty members, people just looked at him. Even those who had heard of it regarded it merely as a novelty fabricated by the telephone company. There was no course work involving transistors or the theory of solid-state electronics. His dissertation was a "Photoelectric Study of Surface States on Insulators," which was at best merely background for solid-state electronics. In this area MIT was far behind Grinnell College. For a good four years Grant Gale remained one of the few people Bob Noyce could compare notes with in this new field.
Well, it had been a close one! What if Grant Gale hadn't gone to school with John Bardeen, and what if Oliver Buckley hadn't been a Grinnell alumnus? And what if Gale hadn't bothered to get in touch with the two of them after he read the little squib about the transistor in the newspaper? What if he hadn't gone to bat for Bob Noyce after the Night of the Luau Pig and the boy had been thrown out of college and that had been that? After all, if Bob hadn't been able to finish at Grinnell, he probably never would have been introduced to the transistor. He certainly wouldn't have come across it at MIT in 1948. Given what Bob Noyce did over the next twenty years, one couldn't help but wonder about the fortuitous chain of events.
Fortuitous. . . well! How Josiah Grinnell, up on the plains of Heaven, must have laughed over that!
GRANT GALE WAS the first important physicist in Bob Noyce's career. The second was William Shockley. After their ambitions had collided one last time, and they had parted company, Noyce had concluded that he and Shockley were two very different people. But in many ways they were alike
For a start, they both had an amateur's hambone love of being on-stage. At MIT Noyce had sung in choral groups. Early in the summer of 1953, after he had received his Ph.D., he went over to Tufts College to sing and act in a program of musicals presented by the college. The costume director was a girl named Elizabeth Bottomley, from Barrington, Rhode Island, who had just graduated from Tufts, majoring in English. They both enjoyed dramatics. Singing, acting, and skiing had become the pastimes Noyce enjoyed most. He had become almost as expert at skiing as he had been at diving. Noyce and Betty, as he called her, were married that fall.
In 1953 the MIT faculty was just beginning to understand the implications of the transistor. But electronics firms were already eager to have graduate electrical engineers who could do research and development in the new field. Noyce was offered jobs by Bell Laboratories, IBM, by RCA, and Philco. He went to work for Philco, in Philadelphia, because Philco was starting from near zero in semiconductor research and chances for rapid advancement seemed good. But Noyce was well aware that the most important work was still being done at Bell Laboratories, thanks in no small part to William Shockley.
Shockley had devised the first theoretical framework for research into solid-state semiconductors as far back as 1939 and was in charge of the Bell Labs team that included John Bardeen and Walter Brattain. Shockley had also originated the "junction transistor," which turned the transistor from an exotic laboratory instrument into a workable item. By 1955 Shockley had left Bell and returned to Palo Alto, California, where he had grown up near Stanford University, to form his own company, Shockley Semiconductor Laboratory, with start up money provided by Arnold Beckman of Beckman Instruments. Shockley opened up shop in a glorified shed on South San Antonio Road in Mountain View, which was just south of Palo Alto. The building was made of concrete blocks with the rafters showing. Aside from clerical and maintenance personnel, practically all the employees were electrical engineers with doctorates. In a field this experimental there was nobody else worth hiring. Shockley began talking about "my Ph.D. production line. "
Meanwhile, Noyce was not finding Philco the golden opportunity he thought it would be. Philco wanted good enough transistors to stay in the game with GE and RCA, but it was not interested in putting money into the sort of avant-garde research Noyce had in mind. In 1956 he resigned from Philco and moved from Pennsylvania to California to join Shockley. The way he went about it was a classic example of the Noyce brand of confidence. By now he and his wife, Betty, had two children: Bill, who was two, and Penny, who was six months old. After a couple of telephone conversations with Shockley, Noyce put himself and Betty on a night flight from Philadelphia to San Francisco. They arrived in Palo Alto at six A.M. By noon Noyce had signed a contract to buy a house. That afternoon he went to Mountain View to see Shockley and ask for a job, projected the halo, and got it.
The first months on Shockley's Ph.D. production line were exhilarating. It wasn't really a production line at all. Everything at this stage was research. Every day a dozen young Ph.D.'s came to the shed at eight in the morning and began heating germanium and silicon, another common element, in kilns to temperatures ranging from 1,472 to 2,552 degrees Fahrenheit. They wore white lab coats, goggles, and work gloves. When they opened the kiln doors weird streaks of orange and white light went across their faces, and they put in the germanium or the silicon, along with specks of aluminum, phosphorus, boron. and arsenic. Contaminating the germanium or silicon with the aluminum, phosphorus, boron, and arsenic was called doping. Then they lowered a small mechanical column into the goo so that crystals formed on the bottom of the column, and they pulled the crystal out and tried to get a grip on it with tweezers, and put it under microscopes and cut it with diamond cutters, among other things, into minute slices, wafers, chips; there were no names in electronics for these tiny forms. The kilns cooked and bubbled away, the doors opened, the pale apricot light streaked over the goggles, the tweezers and diamond cutters flashed, the white coats flapped, the Ph. D.'s squinted through their microscopes, and Shockley moved between the tables conducting the arcane symphony.
In pensive moments Shockley looked very much the scholar, with his roundish face, his roundish eyeglasses, and his receding hairline; but Shockley was not a man locked in the pensive mode. He was an enthusiast, a raconteur, and a showman. At the outset his very personality was enough to keep everyone swept up in the great adventure. When he lectured, as he often did at colleges and before professional groups, he would walk up to the lectern and thank the master of ceremonies and say that the only more flattering introduction he had ever received was one he gave himself one night when the emcee didn't show up, whereupon - bango!- a bouquet of red roses would pop up in his hand. Or he would walk up to the lectern and say that tonight he was getting into a hot subject, whereupon he would open up a book and - whump! -a puff of smoke would rise up out of the pages.
Shockley was famous for his homely but shrewd examples. One day a student confessed to being puzzled by the concept of amplification, which was one of the prime functions of the transistor. Shockley told him: "If you take a bale of hay and tie it to the tail of a mule and then strike a match and set the bale of hay on fire, and if you then compare the energy expended shortly thereafter by the mule with the energy expended by yourself in the striking of the match, you will understand the concept of amplification."
On November 1,1956, Shockley arrived at the shed on South San Antonio Road beaming. Early that morning he had received a telephone call informing him that he had won the Nobel Prize for physics for the invention of the transistor; or, rather, that he was co-winner, along with John Bardeen and Walter Brattain. Shockley closed up shop and took everybody to a restaurant called Dinah's Shack over on El Camino Real, the road to San Francisco that had become Palo Alto's commercial strip. He treated his Ph. D. production line and all the other employees to a champagne breakfast. It seemed that Shockley's father was a mining engineer who spent years out on remote durango terrain, in Nevada, Manchuria and all over the world. Shockley's mother was like Noyce's. She was an intelligent woman with a commanding will. The Shockleys were Unitarians, the Unitarian Church being an offshoot of the Congregational. Shockley Sr. was twenty years older than Shockley's mother and died when Shockley was seventeen. Shockley's mother was determined that her son would someday "set the world on fire," as she once put it. And now he had done it. Shockley lifted a glass of champagne in Dinah's Shack, and it was as if it were a toast back across a lot of hardwrought durango grit Octagon Soap sagebrush Dissenting Protestant years to his father's memory and his mother's determination.
That had been a great day at Shockley Semiconductor Laboratory. There weren't many more. Shockley was magnetic, he was a genius, and he was a great research director? the best, in fact. His forte was breaking a problem down to first principles. With a few words and a few lines on a piece of paper he aimed any experiment in the right direction. When it came to comprehending the young engineers on his Ph.D. production line, however, he was not so terrific.
It never seemed to occur to Shockley that his twelve highly educated elves just might happen to view themselves the same way he had always viewed himself: which is to say, as young geniuses capable of the sort of inventions Nobel Prizes were given for. One day Noyce came to Shockley with some new results he had found in the laboratory. Shockley picked up the telephone and called some former colleagues at Bell Labs to see if they sounded right. Shockley never even realized that Noyce had gone away from his desk seething. Then there was the business of the new management techniques. Now that he was an entrepreneur, Shockley came up with some new ways to run a company. Each one seemed to irritate the elves more than the one before. For a start, Shockley published their salaries. He posted them on a bulletin board. That way there would be no secrets. Then he started having the employees rate one another on a regular basis. These were so-called peer ratings, a device sometimes used in the military and seldom appreciated even there. Everybody regarded peer ratings as nothing more than popularity contests. But the real turning point was the lie detector. Shockley was convinced that someone in the shed was sabotaging the project. The work was running into inexplicable delays, but the money was running out on schedule. So he insisted that one employee roll up his sleeve and bare his chest and let the electrodes be attached and submit to a polygraph examination. No saboteur was ever found.
There were also some technical differences of opinion. Shockley was interested in developing a so-called four-layer diode. Noyce and two of his fellow elves, Gordon Moore and Jean Hoerni, favored transistors. But at bottom it was dissatisfaction with the boss and the lure of entrepreneurship that led to what happened next.
In the summer of 1957 Moore, Hoerni, and five other engineers, but not Noyce, got together and arrived at what became one of the primary business concepts of the young semiconductor industry. In this business, it dawned on them, capital assets in the traditional sense of plant, equipment, and raw materials counted for next to nothing. The only plant you needed was a shed big enough for the worktables. The only equipment you needed was some kilns, goggles, microscopes, tweezers, and diamond cutters. The materials, silicon and germanium, came from dirt and coal. Brainpower was the entire franchise. If the seven of them thought they could do the job better than Shockley, there was nothing to keep them from starting their own company. On that day was born the concept that would make the semiconductor business as wild as show business: defection capital.
The seven defectors went to the Wall Street firm of Hayden Stone in search of start-up money. It was at this point that they realized they had to have someone to serve as administrator. So they turned to Noyce, who was still with Shockley. None of them, including Noyce, had any administrative experience, but they all thought of Noyce as soon as the question came up. They didn't know exactly what they were looking for... but Noyce was the one with the halo. He agreed to join them. He would continue to wear a white lab coat and goggles and do research. But he would also be the coordinator. Of the eight of them, he would be the one man who kept track, on a regular basis, of all sides of the operation. He was twenty-nine years old.
Arthur Rock of Hayden Stone approached twenty-two firms before he finally hooked the defectors up with the Fairchild Camera and Instrument Corporation of New York. Fairchild was owned by Sherman Fairchild, a bachelor bon vivant who lived in a futuristic town house on East Sixty-fifth Street in Manhattan. The house was in two sections connected by ramps. The ramps were fifty feet long in some cases, enclosed in glass so that you could go up and down the ramps in all weather and gaze upon the marble courtyard below. The place looked like something from out of the Crystal Palace of Ming in Flash Gordon. The ramps were for his Aunt May, who lived with him and was confined to a wheelchair and had even more Fairchild money than he did. The chief executive officer of Fairchild was John Carter, who had just come from the Corning Glass Company. He had been the youngest vice president in the history of that old-line, family-owned firm. He was thirty-six. Fairchild Camera and Instrument gave the defectors the money to start up the new company, Fairchild Semiconductor, with the understanding that Fairchild Carnera and Instrument would have the right to buy Fairchild Semiconductor for $3 million at any time within the next eight years.
Shockley took the defections very hard. He seemed as much hurt as angered, and he was certainly angry enough. A friend of Shockley's said to Noyce's wife, Betty: "You must have known about this for quite some time. How on earth could you not tell me?" That was a baffling remark, unless one regarded Shockley as the father of the transistor and the defectors as the children he had taken beneath his mantle of greatness.
If so, one had a point. Years later, if anyone had drawn up a family tree for the semiconductor industry, practically every important branch would have led straight from Shockley's shed on South San Antonio Road. On the other hand, Noyce had been introduced to the transistor not by Shockley but by John Bardeen, via Grant Gale, and not in California but back in his own hometown, Grinnell, Iowa.
For that matter, Josiah Grinnell had been a defector in his day, too, and there was no record that he had ever lost a night's sleep over it.
Noyce, Gordon Moore, Jean Hoerni and the other five defectors set up Fairchild Semiconductor in a two-story warehouse building some speculator had built out of tilt-up concrete slabs on Charleston Avenue in Mountain View, about twelve blocks from Shockley's operation. Mountain View was in the northern end of the Santa Clara Valley. In the business world the valley was known mainly for its apricot, pear, and plum orchards. From the work bays of the light-industry sheds that the speculators were beginning to build in the valley you could look out and see the raggedy little apricot trees they had never bother to buldoze after they bought the land from the farmers. A few well known electronics firms were already in the valley: General Electric and IBM, as well as a company that had started up locally, Hewlett-Packard. Stanford University was encouraging engineering concerns to locate near Palo alto and use the university's research facilities. The man who ran the program was a friend of Shockley's, Frederick E. Terman, whose father had originated the first scientific measurement of human intelligence, the Stanford-Binet IQ test.
IBM had a facility in the valley that was devoted specifically to research rather than production. Both IBM and Hewlett-Packard were trying to develop a highly esoteric and colossally expensive new device, the electronic computer. Shockley had been the first entrepreneur to come to the area to make semiconductors. After the defections his operation never got off the ground. Here in the Santa Clara Valley, that left the field to Noyce and the others at Fairchild.
Fairchild's start-up couldn't have come at a better time. By 1957 there was sufficient demand from manufacturers who merely wanted transistors instead of vacuum tubes, for use in radios and other machines, to justify the new operation. But it was also in 1957 that the Soviet Union launched Sputnik I. In the electronics industry the ensuing space race had the effect of coupling two new inventions?the transistor and the computer?and magnifying the importance of both.
The first American electronic computer known as ENIAC, had been developed by the Army during the Second World War, chiefly as a means of computing artillery and bomb trajectories. The machine was a monster. It was one hundred feet long and ten feet high and required eighteen thousand vacuum tubes. The tubes generated so much heat, the temperature in the room sometimes reached 120 degrees. What the government needed was small computers that could be installed in rockets to provide automatic onboard guidance. Substituting transistors for vacuum tubes was an obvious way to cut down on the size. After Sputnik the glamorous words in the semiconductor business were computers and miniaturization.
Other than Shockley Semiconductor, Fairchild was the only semiconductor company in the Santa Clara Valley, but Texas Instruments had entered the field in Dallas, as had Motorola in Phoenix and Transitron and Raytheon in the Boston area, where a new electronics industry was starting up as MIT finally began to comprehend the new technology. These firms were all racing to refine the production of transistors to the point where they might command the market. So far refinement had not been anybody's long suit. No tourist dropping by Fairchild, Texas Instruments, Motorola, or Transitron would have had the faintest notion he was looking in on the leading edge of the most advanced of all industries, electronics. The work bays, where the transistors were produced looked like slightly sunnier versions of the garment sweatshops of San Francisco's Chinatown. Here were rows of women hunched over worktables, squinting through microscopes doing the most tedious and frustrating sort of manual labor, cutting layers of silicon apart with diamond cutters, picking little rectangles of them up with tweezers, trying to attach wires to them, dropping them, rummaging around on the floor to find them again, swearing, muttering, climbing back up to their chairs, rubbing their eyes, squinting back through the microscopes, and driving themselves crazy some more. Depending on how well the silicon or germanium had been cooked and doped, anywhere from 50 to 90 percent of the transistors would turn out to be defective even after all that, and sometimes the good ones would be the ones that fell on the floor and got ruined.
Even for a machine as simple as a radio the individual transistors had to be wired together, by hand, until you ended up with a little panel that looked like a road map of West Virginia. As for a computer, the wires inside a computer were sheer spaghetti.
Noyce had figured out a solution. But fabricating it was another matter. There was something primitive about cutting individual transistors out of sheets of silicon and then wiring them back together in various series. Why not put them all on a single piece of silicon without wires? The problem was that you would also have to carve, etch, coat, and otherwise fabricate the silicon to perform all the accompanying electrical functions as well, the functions ordinarily performed by insulators, rectifiers, resistors, and capacitors. You would have to create an entire electrical system, an entire circuit, on a little wafer or chip.
Noyce realized that he was not the only engineer thinking along these lines, but he had never even heard of Jack Kilby. Kilby was a thirty-six-year-old engineer working for Texas lnstruments in Dallas. In January, 1959 Noyce made his first detailed notes about a complete solid-state circuit. A month later Texas Instruments announced that Jack Kilby had invented one. Kilby's integrated circuit, as the invention was called, was made of germanium. Six months later Noyce created a similar integrated circuit made of silicon and using a novel insulating process developed by Jean Hoerni. Noyce's silicon device turned out to be more efficient and more practical to produce than Kilby's and set the standard for the industry. So Noyce became known as the co-inventor of the integrated circuit. Nevertheless, Kilby had unquestionably been first. There was an ironic echo of Shockley here. Strictly speaking, Bardeen and Brattain, not Shockley, had invented the transistor, but Shockley wasn't bashful about being known as the co-inventor. And, now eleven years later, Noyce wasn't turning bashful either.
Noyce knew exactly what he possessed in this integrated circuit, or microchip, as the press would call it. Noyce knew that he had discovered the road to El Dorado.
El Dorado was the vast, still-virgin territory of electricity. Electricity was already so familiar a part of everyday life, only a few research engineers understood just how, young and unexplored the terrain actually was. It had been only eighty years since Edison invented the light bulb in 1879. It had been less than fifty years since Lee De Forest, an inventor from Council Bluffs, Iowa had invented the vacuum tube. The vacuum tube was based on the light bulb, but the vacuum tube opened up fields the light bulb did not even suggest: long distance radio and telephone communicatlon. Over the past ten vears, since Bardeen and Brattain invented it in 1948, the transistor had become the modern replacement for the vacuum tube. And now came Kilby's and Noyce's integrated circuit. The integrated circuit was based on the transistor, but the integrated circuit opened up fields the transistor did not even suggest. The integrated circuit made it possible to create miniature computers, to put all the functions of the mighty ENIAC on a panel the size of a playing card. Thereby the integrated circuit opened up every field of engineering imaginable, from voyages to the moon to robots, and many fields that had never been imagined, such as electronic guidance counseling. It opened up so many fields that no one could even come up with a single name to include them all. "The second industrial revolution," "the age of the computer, " "the microchip universe, " "the electronic grid," none of them, not even the handy neologism "high tech. " could encompass all the implications.
The importance of the integrated circuit was certainly not lost on John Carter and Fairchild Camera back un New York. In 1959 they exercised their option to buy Fairchild Semiconductor for $3 million. The next day Noyce, Moore, Hoerni, and the other five former Shockley elves woke up rich, or richer than they had ever dreamed of being. Each received $250,000 worth of Fairchild stock.
Josiah Grinnell grew livid on the subject of alcohol. But he had nothing against money. He would have approved.
Noyce didn't know what to make of his new wealth. He was thirty-one years old. For the past four years, ever since he had gone to work for Shockley, the semiconductor business had not seemed like a business at all but an esoteric game in which young electrical engineers competed for attaboy's and the occasional round of applause after delivering a paper before the IEEE, the Institute of Electrical and Electronics Engineers. It was a game supercharged by the fact that it was being played in the real world, to use a term that annoyed scientists in the universities.
Someone--Arnold Beckman, Sherman Fairchild, whoever--was betting real money, and other bands of young elves, at Texas Instruments, RCA, Bell, were out there competing with you by the real world's rules, which required that you be practical as well as brilliant. Noyce started working for Fairchild Semiconductor in 1957 for twelve thousand dollars a year. When it came to money, he had assumed that he, Like his father, would always be on somebody's payroll. Now, in 1959, when he talked to his father, he told him: "The money doesn't seem real. It's just a way of keeping score."
(continues in Part 2)
America is today in the midst of a great technological revolution. With the advent of the silicon chip, information processing, communications, and the national economy have been strikingly altered. The new technology is changing how we live, how we work, how we think. The revolution didn't just happen; it was engineered by a small number of people, principally Middle Americans, whose horizons were as unlimited as the Iowa sky. collectively, they engineered Tomorrow. Foremost among them is Robert Noyce.

The Tinkerings of Robert Noyce
How the Sun Rose on the Silicon Valley, Part 1
In 1948 there were seven thousand people in Grinnell, Iowa, including more than one who didn't dare take a drink in his own house without pulling the shades down first. It was against the law to sell liquor in Grinnell, but it was perfectly legal to drink it at home. So it wasn't that. It wasn't even that someone might look in through the window and disapprove. God knew Grinnell had more than its share of White Ribbon teetotalers, but by 1948 alcohol was hardly the mark of Cain it had once been. No, those timid souls with their fingers through the shade loops inside the white frame houses on Main Street and Park Street were thinking of something else altogether.
They happened to live on land originally owned by the Congregational minister who had founded the town in 1854, Josiah Grinnell. Josiah Grinnell had sold off lots with covenants, in perpetuity, stating that anyone who allowed alcohol to be drunk on his property forfeited ownership. In perpetuity! In perpetuity was forever, and 1948 was not even a hundred years later. In 1948 there were people walking around Grinnell who had known Josiah Grinnell personally. They were getting old; Grinnell had died in 1891; but they were still walking around. So... why take a chance!
The plain truth was, Grinnell had Middle West written all over it. It was squarely in the middle of Iowa's Midland corn belt, where people on the farms said "crawdad" instead of crayfish and "barn lot" instead of barnyard. Grinnell had been one of many Protestant religious communities established in the mid-nineteenth century after Iowa became a state and settlers from the East headed for the farmlands. The streets were lined with white clapboard houses and elm trees, like a New England village. And today, in 1948, the hard-scrubbed Octagon Soap smell of nineteenth century Protestantism still permeated the houses and Main Street as well. That was no small part of what people in the East thought of when they heard the term "Middle West. " For thirty years writers such as Sherwood Anderson, Sinclair Lewis, and Carl Van Vechten had been prompting the most delicious sniggers with their portraits of the churchy, narrow minded Middle West. The Iowa painter Grant Wood was thinking of farms like the ones around Grinnell when he did his famous painting American Gothic. Easterners recognized the grim, juiceless couple in Wood's picture right away. There were John Calvin's and John Knox's rectitude reigning in the sticks.
In the fall of 1948 Harry Truman picked out Grinnell as one of the stops on his whistle-stop campaign tour, one of the hamlets where he could reach out to the little people, the average Americans of the heartland, the people untouched by the sophisticated opinion-makers of New York and Washington. Speaking from the rear platform of his railroad car, Truman said he would never forget Grinnell, because it was Grinnell College, the little Congregational academy over on Park Street, that had given him his first honorary degree. The President's fond recollection didn't cut much ice, as it turned out. The town had voted Republican in every presidential election since the first time Abraham Lincoln ran, in 1860, and wasn't about to change for Harry Truman.
On the face of it, there you had Grinnell Iowa, in 1948: a piece of mid-nineteenth century American history frozen solid in the middle of the twentieth. It was one of the last towns in America that people back east would have figured to become the starting point of a bolt into the future that would create the very substructure, the electronic grid, of life in the year 2000 and beyond.
On the other hand, it wouldn't have surprised Josiah Grinnell in the slightest.
It was in the summer of 1948 that Grant Gale, a forty-five-year-old physics professor at Grinnell College, ran across an item in the newspaper concerning a former classmate of his at the University of Wisconsin named John Bardeen. Bardeen's father had been dean of medicine at Wisconsin, and Gale's wife Harriet's father had been dean of the engineering school, and so Bardeen and Harriet had grown up as fellow faculty brats, as the phrase went. Both Gale and Bardeen had majored in electrical engineering. Eventually Bardeen had taught physics at the University of Minnesota and had then left the academic world to work for Bell Laboratories, the telephone company's main research center, in Murray Hill, New Jersey. And now, according to the item, Bardeen and another engineer at Bell, Walter Brattain, had invented a novel little device they called a transistor.
It was only an item, however: the invention of the transistor in 1948 did not create headlines. The transistor apparently performed the same function as the vacuum tube, which was an essential component of telephone relay systems and radios. Like the vacuum tube, the transistor could isolate a specific electrical signal, such as a radio wave, and amplify it. But the transistor did not require glass tubing, a vacuum, a plate, or a cathode. It was nothing more than two minute gold wires leading to a piece of processed germanium less than a sixteenth of an inch long. Germanium, an element found in coal, was an insulator, not a conductor. But if the germanium was contaminated with impurities, it became a "semiconductor." A vacuum tube was also a semiconductor; the vacuum itself, like the germanium, was an insulator. But as every owner of a portable radio knew, vacuum tubes drew a lot of current, required a warm-up interval before they would work, and then got very hot. A transistor eliminated all these problems and, on top of that, was about fifty times smaller than a vacuum tube.
So far, however, it was impossible to mass-produce transistors, partly because the gold wires had to be made by hand and attached by hand two thousandths of an inch apart. But that was the telephone company's problem. Grant Gale wasn't interested in any present or future applications of the transistor in terms of products. He hoped the transistor might offer a way to study the flow of electrons through a solid (the germanium), a subject physicists had speculated about for decades. He thought it would be terrific to get some transistors for his physics department at Grinnell. So he wrote to Bardeen at Bell Laboratories. Just to make sure his request didn't get lost in the shuffle, he also wrote to the president of Bell Laboratories, Oliver Buckley. Buckley was from Sloane, Iowa, and happened to be a Grinnell graduate. So by the fall of 1948 Gale had obtained two of the first transistors ever made, and he presented the first academic instruction in solid-state electronics available anywhere in the world, for the benefit of the eighteen students majoring in physics at Grinnell College.
One of Grant Gale's senior physics majors was a local boy named Robert Noyce, whom Gale had known for years. Bob and his brothers, Donald, Gaylord, and Ralph, lived just down Park Street and used to rake leaves, mow the lawn, baby-sit, and do other chores for the Gales. Lately Grant Gale had done more than his share of agonizing over Bob Noyce. Like his brothers, Bob was a bright student, but he had just been thrown out of school for a semester, and it had taken every bit of credit Gale had in the local favor bank, not only with other faculty members but also with the sheriff, to keep the boy from being expelled for good and stigmatized with a felony conviction.
Bob Noyce's father, Ralph Sr. was a Congregational minister. Not only that, both of his grandfathers were Congregational ministers. But that hadn't helped at all. In an odd way, after the thing happened, the boy's clerical lineage had boomeranged on him. People were going around saying, "Well, what do you expect from a preacher's son?" It was as if people in Grinnell unconsciously agreed with Sherwood Anderson that underneath the righteousness the midwestern Protestant preachers urged upon them, and which they themselves professed to uphold, lived demons of weakness, perversion, and hypocrisy that would break loose sooner or later.
No one denied that the Noyce boys were polite and proper in all outward appearances. They were all members of the Boy Scouts. They went to Sunday School and the main Sunday service at the First Congregational Church and were active in the church youth groups. They were pumped full of Congregationalism until it was spilling over. Their father, although a minister, was not the minister of the First Congregational Church. He was the associate superintendent of the Iowa Conference of Congregational Churches, whose headquarters were at the college. The original purpose of the college had been to provide a good academic Congregational education, and many of the graduates became teachers. The Conference was a coordinating council rather than a governing body, since a prime tenet of the Congregational Church embedded in its name, was that each congregation was autonomous. Congregationalists rejected the very idea of a church hierarchy. A Congregational minister was not supposed to be a father or even a shepherd, but, rather, a teacher. Each member of the congregation was supposed to internalize the moral precepts of the church and be his own priest dealing directly with God. So the job of secretary of the Iowa Conference of Congregational Churches was anything but a position of power. It didn't pay much, either.
The Noyces didn't own their own house. They lived in a two-story white clapboard house that was owned by the church at Park Street and Tenth Avenue, at the college.
Not having your own house didn't carry the social onus in Grinnell that it did in the East. There was no upper crust in Grinnell. There were no top people who kept the social score in such matters. Congregationalists rejected the idea of a social hierarchy as fiercely as they did the idea of a religious hierarchy. The Congregationalists, like the Presbyterians, Methodists, Baptists, and United Brethren, were Dissenting Protestants. They were direct offshoots of the Separatists, who had split off from the Church of England in the sixteenth and seventeenth centuries and settled New England. At bottom, their doctrine of the autonomous congregation was derived from their hatred of the British system of class and status, with its endless gradations, topped off by the Court and the aristocracy. Even as late as 1948 the typical small town of the Middle West, like Grinnell, had nothing approaching a country club set. There were subtle differences in status in Grinnell, as in any other place, and it was better to be rich than poor, but there were only two obvious social ranks: those who were devout, educated, and hardworking, and those who weren't. Genteel poverty did not doom one socially in Grinnell. Ostentation did. The Noyce boys worked at odd jobs to earn their pocket money. That was socially correct as well as useful. To have devoted the same time to taking tennis lessons or riding lessons would have been a gaffe in Grinnell.
Donald, the oldest of the four boys, had done brilliantly at the college and had just received his Ph.D. in chemistry at Columbia University and was about to join the faculty of the University of California at Berkeley. Gaylord, the second oldest, was teaching school in Turkey. Bob, who was a year younger than Gaylord, had done so well in science at Grinnell High School that Grant Gale had invited him to take the freshman physics course at the college during his high school senior year. He became one of Gale's star students and most tireless laboratory workers from that time on. Despite his apparent passion for the scientific grind, Bob Noyce turned out to be that much-vaunted creature, the well-rounded student. He was a trim, muscular boy, five feet eight, with thick dark brown hair, a strong jawline, and a long, broad nose that gave him a rugged appearance. He was the star diver on the college swimming team and won the Midwest Conference championship in 1947. He sang in choral groups, played the oboe, and was an actor with the college dramatic society. He also acted in a radio drama workshop at the college, along with his friend Peter Hackes and some others who were interested in broadcasting, and was the leading man in a soap opera that was broadcast over station WOI in Ames, Iowa.
Perhaps Bob Noyce was a bit too well rounded for local tastes. There were people who still remembered the business with the box kite back in 1941, when he was thirteen. It had been harmless, but it could have been a disaster. Bob had come across some plans for the building of a box kite, a kite that could carry a person aloft, in the magazine Popular Science. So he and Gaylord made a frame of cross-braced pine and covered it with a bolt of muslin. They tried to get the thing up by running across a field and towing it with a rope, but that didn't work terribly well. Then they hauled it up on the roof of a barn, and Bob sat in the seat and Gaylord ran across the roof, pulling the kite. and Bob was lucky he didn't break his neck when he and the thing hit the ground. So then they tied it to the rear bumper of a neighbor's car. With the neighbor at the wheel, Bob rode the kite and managed to get about twelve feet off the ground and glide for thirty seconds or so and come down without wrecking himself or any citizen's house or livestock.
Livestock. . . yes. Livestock was a major capital asset in Grinnell, and livestock was at the heart of what happened in 1948. In May a group of Bob Noyce's friends in one of the dormitory houses at Grinnell decided to have a luau, and he was in on the planning. The Second World War had popularized the exotic ways of the South Pacific, so that in 1948 the luau was an up-to-the-minute social innovation. The centerpiece of a luau was a whole roasted suckling pig with an apple or a pineapple in its mouth. Bob Noyce, being strong and quick, was one of the two boys assigned to procure the pig. That night they sneaked onto a farm just outside of Grinnell and wrestled a twenty-five-pound suckling out of the pigpen and arrived back at the luau to great applause. Within a few hours the pig was crackling hot and had an apple in its mouth and looked good enough for seconds and thirds, which everybody helped himself to, and there was more applause. The next morning came the moral hangover. The two boys decided to go see the farmer, confess, and pay for the pig. They didn't quite understand how a college luau, starring his pig, would score on the laugh meter with a farmer in midland Iowa. In the state of Iowa, where the vast majority of people depended upon agriculture for a livelihood and upon Protestant morality for their standards, not even stealing a watermelon worth thirty-five cents was likely to be written off as a boyish prank. Stealing a pig was larceny. The farmer got the sheriff and insisted on bringing criminal charges. There was only so much that Ralph Noyce, the preacher with the preacher's son, could do. Grant Gale, on the other hand, was the calm, well-respected third party. He had two difficult tasks: to keep Bob out of jail and out of court and to keep the college administration from expelling him. There was never any hope at all of a mere slap on the wrist. The compromise Grant Gale helped work out? a one-semester suspension? was the best deal Bob could have hoped for realistically.
The Night of the Luau Pig was quite a little scandal on the Grinnell Richter scale. So Gale was all the more impressed by the way Bob Noyce took it. The local death-ray glowers never broke his confidence. All the Noyce boys had a profound and, to tell the truth, baffling confidence. Bob had a certain way of listening and staring. He would lower his head slightly and look up with a gaze that seemed to be about one hundred amperes. While he looked at you he never blinked and never swallowed. He absorbed everything you said and then answered very levelly in a soft baritone voice and often with a smile that showed off his terrific set of teeth. The stare, the voice, the smile; it was all a bit like the movie persona of the most famous of all Grinnell College's alumni, Gary Cooper. With his strong face, his athlete's build, and the Gary Cooper manner, Bob Noyce projected what psychologists call the halo effect. People with the halo effect seem to know exactly what they're doing and, moreover, make you want to admire them for it. They make you see the halos over their heads.
Years later people would naturally wonder where Bob Noyce got his confidence. Many came to the conclusion it was as, much from his mother, Harriett Norton Noyce, as from his father. She was a latter-day version of the sort of strong-willed, intelligent, New England-style woman who had made such a difference during Iowa's pioneer days a hundred years before. His mother and father, with the help of Rowland Cross, who taught mathematics at Grinnell, arranged for Bob to take a job in the actuarial department of Equitable Life in New York City for the summer. He stayed on at the job during the fall semester, then came back to Grinnell at Christmas and rejoined the senior class in January as the second semester began. Gale was impressed by the aplomb with which the prodigal returned. In his first three years Bob had accumulated so many extra credits, it would take him only this final semester to graduate. He resumed college life, including the extracurricular activities, without skipping a beat. But more than that, Gale was gratified by the way Bob became involved with the new experimental device that was absorbing so much of Gale's own time: the transistor.
Bob was not the only physics major interested in the transistor, but he was the one who seemed most curious about where this novel mechanism might lead. He went off to the Massachusetts Institute of Technology, in Cambridge, in the fall to begin his graduate work. When he brought up the subject of the transistor at MIT, even to faculty members, people just looked at him. Even those who had heard of it regarded it merely as a novelty fabricated by the telephone company. There was no course work involving transistors or the theory of solid-state electronics. His dissertation was a "Photoelectric Study of Surface States on Insulators," which was at best merely background for solid-state electronics. In this area MIT was far behind Grinnell College. For a good four years Grant Gale remained one of the few people Bob Noyce could compare notes with in this new field.
Well, it had been a close one! What if Grant Gale hadn't gone to school with John Bardeen, and what if Oliver Buckley hadn't been a Grinnell alumnus? And what if Gale hadn't bothered to get in touch with the two of them after he read the little squib about the transistor in the newspaper? What if he hadn't gone to bat for Bob Noyce after the Night of the Luau Pig and the boy had been thrown out of college and that had been that? After all, if Bob hadn't been able to finish at Grinnell, he probably never would have been introduced to the transistor. He certainly wouldn't have come across it at MIT in 1948. Given what Bob Noyce did over the next twenty years, one couldn't help but wonder about the fortuitous chain of events.
Fortuitous. . . well! How Josiah Grinnell, up on the plains of Heaven, must have laughed over that!
GRANT GALE WAS the first important physicist in Bob Noyce's career. The second was William Shockley. After their ambitions had collided one last time, and they had parted company, Noyce had concluded that he and Shockley were two very different people. But in many ways they were alike
For a start, they both had an amateur's hambone love of being on-stage. At MIT Noyce had sung in choral groups. Early in the summer of 1953, after he had received his Ph.D., he went over to Tufts College to sing and act in a program of musicals presented by the college. The costume director was a girl named Elizabeth Bottomley, from Barrington, Rhode Island, who had just graduated from Tufts, majoring in English. They both enjoyed dramatics. Singing, acting, and skiing had become the pastimes Noyce enjoyed most. He had become almost as expert at skiing as he had been at diving. Noyce and Betty, as he called her, were married that fall.
In 1953 the MIT faculty was just beginning to understand the implications of the transistor. But electronics firms were already eager to have graduate electrical engineers who could do research and development in the new field. Noyce was offered jobs by Bell Laboratories, IBM, by RCA, and Philco. He went to work for Philco, in Philadelphia, because Philco was starting from near zero in semiconductor research and chances for rapid advancement seemed good. But Noyce was well aware that the most important work was still being done at Bell Laboratories, thanks in no small part to William Shockley.
Shockley had devised the first theoretical framework for research into solid-state semiconductors as far back as 1939 and was in charge of the Bell Labs team that included John Bardeen and Walter Brattain. Shockley had also originated the "junction transistor," which turned the transistor from an exotic laboratory instrument into a workable item. By 1955 Shockley had left Bell and returned to Palo Alto, California, where he had grown up near Stanford University, to form his own company, Shockley Semiconductor Laboratory, with start up money provided by Arnold Beckman of Beckman Instruments. Shockley opened up shop in a glorified shed on South San Antonio Road in Mountain View, which was just south of Palo Alto. The building was made of concrete blocks with the rafters showing. Aside from clerical and maintenance personnel, practically all the employees were electrical engineers with doctorates. In a field this experimental there was nobody else worth hiring. Shockley began talking about "my Ph.D. production line. "
Meanwhile, Noyce was not finding Philco the golden opportunity he thought it would be. Philco wanted good enough transistors to stay in the game with GE and RCA, but it was not interested in putting money into the sort of avant-garde research Noyce had in mind. In 1956 he resigned from Philco and moved from Pennsylvania to California to join Shockley. The way he went about it was a classic example of the Noyce brand of confidence. By now he and his wife, Betty, had two children: Bill, who was two, and Penny, who was six months old. After a couple of telephone conversations with Shockley, Noyce put himself and Betty on a night flight from Philadelphia to San Francisco. They arrived in Palo Alto at six A.M. By noon Noyce had signed a contract to buy a house. That afternoon he went to Mountain View to see Shockley and ask for a job, projected the halo, and got it.
The first months on Shockley's Ph.D. production line were exhilarating. It wasn't really a production line at all. Everything at this stage was research. Every day a dozen young Ph.D.'s came to the shed at eight in the morning and began heating germanium and silicon, another common element, in kilns to temperatures ranging from 1,472 to 2,552 degrees Fahrenheit. They wore white lab coats, goggles, and work gloves. When they opened the kiln doors weird streaks of orange and white light went across their faces, and they put in the germanium or the silicon, along with specks of aluminum, phosphorus, boron. and arsenic. Contaminating the germanium or silicon with the aluminum, phosphorus, boron, and arsenic was called doping. Then they lowered a small mechanical column into the goo so that crystals formed on the bottom of the column, and they pulled the crystal out and tried to get a grip on it with tweezers, and put it under microscopes and cut it with diamond cutters, among other things, into minute slices, wafers, chips; there were no names in electronics for these tiny forms. The kilns cooked and bubbled away, the doors opened, the pale apricot light streaked over the goggles, the tweezers and diamond cutters flashed, the white coats flapped, the Ph. D.'s squinted through their microscopes, and Shockley moved between the tables conducting the arcane symphony.
In pensive moments Shockley looked very much the scholar, with his roundish face, his roundish eyeglasses, and his receding hairline; but Shockley was not a man locked in the pensive mode. He was an enthusiast, a raconteur, and a showman. At the outset his very personality was enough to keep everyone swept up in the great adventure. When he lectured, as he often did at colleges and before professional groups, he would walk up to the lectern and thank the master of ceremonies and say that the only more flattering introduction he had ever received was one he gave himself one night when the emcee didn't show up, whereupon - bango!- a bouquet of red roses would pop up in his hand. Or he would walk up to the lectern and say that tonight he was getting into a hot subject, whereupon he would open up a book and - whump! -a puff of smoke would rise up out of the pages.
Shockley was famous for his homely but shrewd examples. One day a student confessed to being puzzled by the concept of amplification, which was one of the prime functions of the transistor. Shockley told him: "If you take a bale of hay and tie it to the tail of a mule and then strike a match and set the bale of hay on fire, and if you then compare the energy expended shortly thereafter by the mule with the energy expended by yourself in the striking of the match, you will understand the concept of amplification."
On November 1,1956, Shockley arrived at the shed on South San Antonio Road beaming. Early that morning he had received a telephone call informing him that he had won the Nobel Prize for physics for the invention of the transistor; or, rather, that he was co-winner, along with John Bardeen and Walter Brattain. Shockley closed up shop and took everybody to a restaurant called Dinah's Shack over on El Camino Real, the road to San Francisco that had become Palo Alto's commercial strip. He treated his Ph. D. production line and all the other employees to a champagne breakfast. It seemed that Shockley's father was a mining engineer who spent years out on remote durango terrain, in Nevada, Manchuria and all over the world. Shockley's mother was like Noyce's. She was an intelligent woman with a commanding will. The Shockleys were Unitarians, the Unitarian Church being an offshoot of the Congregational. Shockley Sr. was twenty years older than Shockley's mother and died when Shockley was seventeen. Shockley's mother was determined that her son would someday "set the world on fire," as she once put it. And now he had done it. Shockley lifted a glass of champagne in Dinah's Shack, and it was as if it were a toast back across a lot of hardwrought durango grit Octagon Soap sagebrush Dissenting Protestant years to his father's memory and his mother's determination.
That had been a great day at Shockley Semiconductor Laboratory. There weren't many more. Shockley was magnetic, he was a genius, and he was a great research director? the best, in fact. His forte was breaking a problem down to first principles. With a few words and a few lines on a piece of paper he aimed any experiment in the right direction. When it came to comprehending the young engineers on his Ph.D. production line, however, he was not so terrific.
It never seemed to occur to Shockley that his twelve highly educated elves just might happen to view themselves the same way he had always viewed himself: which is to say, as young geniuses capable of the sort of inventions Nobel Prizes were given for. One day Noyce came to Shockley with some new results he had found in the laboratory. Shockley picked up the telephone and called some former colleagues at Bell Labs to see if they sounded right. Shockley never even realized that Noyce had gone away from his desk seething. Then there was the business of the new management techniques. Now that he was an entrepreneur, Shockley came up with some new ways to run a company. Each one seemed to irritate the elves more than the one before. For a start, Shockley published their salaries. He posted them on a bulletin board. That way there would be no secrets. Then he started having the employees rate one another on a regular basis. These were so-called peer ratings, a device sometimes used in the military and seldom appreciated even there. Everybody regarded peer ratings as nothing more than popularity contests. But the real turning point was the lie detector. Shockley was convinced that someone in the shed was sabotaging the project. The work was running into inexplicable delays, but the money was running out on schedule. So he insisted that one employee roll up his sleeve and bare his chest and let the electrodes be attached and submit to a polygraph examination. No saboteur was ever found.
There were also some technical differences of opinion. Shockley was interested in developing a so-called four-layer diode. Noyce and two of his fellow elves, Gordon Moore and Jean Hoerni, favored transistors. But at bottom it was dissatisfaction with the boss and the lure of entrepreneurship that led to what happened next.
In the summer of 1957 Moore, Hoerni, and five other engineers, but not Noyce, got together and arrived at what became one of the primary business concepts of the young semiconductor industry. In this business, it dawned on them, capital assets in the traditional sense of plant, equipment, and raw materials counted for next to nothing. The only plant you needed was a shed big enough for the worktables. The only equipment you needed was some kilns, goggles, microscopes, tweezers, and diamond cutters. The materials, silicon and germanium, came from dirt and coal. Brainpower was the entire franchise. If the seven of them thought they could do the job better than Shockley, there was nothing to keep them from starting their own company. On that day was born the concept that would make the semiconductor business as wild as show business: defection capital.
The seven defectors went to the Wall Street firm of Hayden Stone in search of start-up money. It was at this point that they realized they had to have someone to serve as administrator. So they turned to Noyce, who was still with Shockley. None of them, including Noyce, had any administrative experience, but they all thought of Noyce as soon as the question came up. They didn't know exactly what they were looking for... but Noyce was the one with the halo. He agreed to join them. He would continue to wear a white lab coat and goggles and do research. But he would also be the coordinator. Of the eight of them, he would be the one man who kept track, on a regular basis, of all sides of the operation. He was twenty-nine years old.
Arthur Rock of Hayden Stone approached twenty-two firms before he finally hooked the defectors up with the Fairchild Camera and Instrument Corporation of New York. Fairchild was owned by Sherman Fairchild, a bachelor bon vivant who lived in a futuristic town house on East Sixty-fifth Street in Manhattan. The house was in two sections connected by ramps. The ramps were fifty feet long in some cases, enclosed in glass so that you could go up and down the ramps in all weather and gaze upon the marble courtyard below. The place looked like something from out of the Crystal Palace of Ming in Flash Gordon. The ramps were for his Aunt May, who lived with him and was confined to a wheelchair and had even more Fairchild money than he did. The chief executive officer of Fairchild was John Carter, who had just come from the Corning Glass Company. He had been the youngest vice president in the history of that old-line, family-owned firm. He was thirty-six. Fairchild Camera and Instrument gave the defectors the money to start up the new company, Fairchild Semiconductor, with the understanding that Fairchild Carnera and Instrument would have the right to buy Fairchild Semiconductor for $3 million at any time within the next eight years.
Shockley took the defections very hard. He seemed as much hurt as angered, and he was certainly angry enough. A friend of Shockley's said to Noyce's wife, Betty: "You must have known about this for quite some time. How on earth could you not tell me?" That was a baffling remark, unless one regarded Shockley as the father of the transistor and the defectors as the children he had taken beneath his mantle of greatness.
If so, one had a point. Years later, if anyone had drawn up a family tree for the semiconductor industry, practically every important branch would have led straight from Shockley's shed on South San Antonio Road. On the other hand, Noyce had been introduced to the transistor not by Shockley but by John Bardeen, via Grant Gale, and not in California but back in his own hometown, Grinnell, Iowa.
For that matter, Josiah Grinnell had been a defector in his day, too, and there was no record that he had ever lost a night's sleep over it.
Noyce, Gordon Moore, Jean Hoerni and the other five defectors set up Fairchild Semiconductor in a two-story warehouse building some speculator had built out of tilt-up concrete slabs on Charleston Avenue in Mountain View, about twelve blocks from Shockley's operation. Mountain View was in the northern end of the Santa Clara Valley. In the business world the valley was known mainly for its apricot, pear, and plum orchards. From the work bays of the light-industry sheds that the speculators were beginning to build in the valley you could look out and see the raggedy little apricot trees they had never bother to buldoze after they bought the land from the farmers. A few well known electronics firms were already in the valley: General Electric and IBM, as well as a company that had started up locally, Hewlett-Packard. Stanford University was encouraging engineering concerns to locate near Palo alto and use the university's research facilities. The man who ran the program was a friend of Shockley's, Frederick E. Terman, whose father had originated the first scientific measurement of human intelligence, the Stanford-Binet IQ test.
IBM had a facility in the valley that was devoted specifically to research rather than production. Both IBM and Hewlett-Packard were trying to develop a highly esoteric and colossally expensive new device, the electronic computer. Shockley had been the first entrepreneur to come to the area to make semiconductors. After the defections his operation never got off the ground. Here in the Santa Clara Valley, that left the field to Noyce and the others at Fairchild.
Fairchild's start-up couldn't have come at a better time. By 1957 there was sufficient demand from manufacturers who merely wanted transistors instead of vacuum tubes, for use in radios and other machines, to justify the new operation. But it was also in 1957 that the Soviet Union launched Sputnik I. In the electronics industry the ensuing space race had the effect of coupling two new inventions?the transistor and the computer?and magnifying the importance of both.
The first American electronic computer known as ENIAC, had been developed by the Army during the Second World War, chiefly as a means of computing artillery and bomb trajectories. The machine was a monster. It was one hundred feet long and ten feet high and required eighteen thousand vacuum tubes. The tubes generated so much heat, the temperature in the room sometimes reached 120 degrees. What the government needed was small computers that could be installed in rockets to provide automatic onboard guidance. Substituting transistors for vacuum tubes was an obvious way to cut down on the size. After Sputnik the glamorous words in the semiconductor business were computers and miniaturization.
Other than Shockley Semiconductor, Fairchild was the only semiconductor company in the Santa Clara Valley, but Texas Instruments had entered the field in Dallas, as had Motorola in Phoenix and Transitron and Raytheon in the Boston area, where a new electronics industry was starting up as MIT finally began to comprehend the new technology. These firms were all racing to refine the production of transistors to the point where they might command the market. So far refinement had not been anybody's long suit. No tourist dropping by Fairchild, Texas Instruments, Motorola, or Transitron would have had the faintest notion he was looking in on the leading edge of the most advanced of all industries, electronics. The work bays, where the transistors were produced looked like slightly sunnier versions of the garment sweatshops of San Francisco's Chinatown. Here were rows of women hunched over worktables, squinting through microscopes doing the most tedious and frustrating sort of manual labor, cutting layers of silicon apart with diamond cutters, picking little rectangles of them up with tweezers, trying to attach wires to them, dropping them, rummaging around on the floor to find them again, swearing, muttering, climbing back up to their chairs, rubbing their eyes, squinting back through the microscopes, and driving themselves crazy some more. Depending on how well the silicon or germanium had been cooked and doped, anywhere from 50 to 90 percent of the transistors would turn out to be defective even after all that, and sometimes the good ones would be the ones that fell on the floor and got ruined.
Even for a machine as simple as a radio the individual transistors had to be wired together, by hand, until you ended up with a little panel that looked like a road map of West Virginia. As for a computer, the wires inside a computer were sheer spaghetti.
Noyce had figured out a solution. But fabricating it was another matter. There was something primitive about cutting individual transistors out of sheets of silicon and then wiring them back together in various series. Why not put them all on a single piece of silicon without wires? The problem was that you would also have to carve, etch, coat, and otherwise fabricate the silicon to perform all the accompanying electrical functions as well, the functions ordinarily performed by insulators, rectifiers, resistors, and capacitors. You would have to create an entire electrical system, an entire circuit, on a little wafer or chip.
Noyce realized that he was not the only engineer thinking along these lines, but he had never even heard of Jack Kilby. Kilby was a thirty-six-year-old engineer working for Texas lnstruments in Dallas. In January, 1959 Noyce made his first detailed notes about a complete solid-state circuit. A month later Texas Instruments announced that Jack Kilby had invented one. Kilby's integrated circuit, as the invention was called, was made of germanium. Six months later Noyce created a similar integrated circuit made of silicon and using a novel insulating process developed by Jean Hoerni. Noyce's silicon device turned out to be more efficient and more practical to produce than Kilby's and set the standard for the industry. So Noyce became known as the co-inventor of the integrated circuit. Nevertheless, Kilby had unquestionably been first. There was an ironic echo of Shockley here. Strictly speaking, Bardeen and Brattain, not Shockley, had invented the transistor, but Shockley wasn't bashful about being known as the co-inventor. And, now eleven years later, Noyce wasn't turning bashful either.
Noyce knew exactly what he possessed in this integrated circuit, or microchip, as the press would call it. Noyce knew that he had discovered the road to El Dorado.
El Dorado was the vast, still-virgin territory of electricity. Electricity was already so familiar a part of everyday life, only a few research engineers understood just how, young and unexplored the terrain actually was. It had been only eighty years since Edison invented the light bulb in 1879. It had been less than fifty years since Lee De Forest, an inventor from Council Bluffs, Iowa had invented the vacuum tube. The vacuum tube was based on the light bulb, but the vacuum tube opened up fields the light bulb did not even suggest: long distance radio and telephone communicatlon. Over the past ten vears, since Bardeen and Brattain invented it in 1948, the transistor had become the modern replacement for the vacuum tube. And now came Kilby's and Noyce's integrated circuit. The integrated circuit was based on the transistor, but the integrated circuit opened up fields the transistor did not even suggest. The integrated circuit made it possible to create miniature computers, to put all the functions of the mighty ENIAC on a panel the size of a playing card. Thereby the integrated circuit opened up every field of engineering imaginable, from voyages to the moon to robots, and many fields that had never been imagined, such as electronic guidance counseling. It opened up so many fields that no one could even come up with a single name to include them all. "The second industrial revolution," "the age of the computer, " "the microchip universe, " "the electronic grid," none of them, not even the handy neologism "high tech. " could encompass all the implications.
The importance of the integrated circuit was certainly not lost on John Carter and Fairchild Camera back un New York. In 1959 they exercised their option to buy Fairchild Semiconductor for $3 million. The next day Noyce, Moore, Hoerni, and the other five former Shockley elves woke up rich, or richer than they had ever dreamed of being. Each received $250,000 worth of Fairchild stock.
Josiah Grinnell grew livid on the subject of alcohol. But he had nothing against money. He would have approved.
Noyce didn't know what to make of his new wealth. He was thirty-one years old. For the past four years, ever since he had gone to work for Shockley, the semiconductor business had not seemed like a business at all but an esoteric game in which young electrical engineers competed for attaboy's and the occasional round of applause after delivering a paper before the IEEE, the Institute of Electrical and Electronics Engineers. It was a game supercharged by the fact that it was being played in the real world, to use a term that annoyed scientists in the universities.
Someone--Arnold Beckman, Sherman Fairchild, whoever--was betting real money, and other bands of young elves, at Texas Instruments, RCA, Bell, were out there competing with you by the real world's rules, which required that you be practical as well as brilliant. Noyce started working for Fairchild Semiconductor in 1957 for twelve thousand dollars a year. When it came to money, he had assumed that he, Like his father, would always be on somebody's payroll. Now, in 1959, when he talked to his father, he told him: "The money doesn't seem real. It's just a way of keeping score."
