William Bradford Shockley (February 13, 1910 – August 12, 1989) was a British-born American physicist and inventor.
Along with John Bardeen and Walter Houser Brattain, Shockley co-invented the transistor, for which all three were awarded the 1956 Nobel Prize in Physics. Shockley's attempts to commercialize a new transistor design in the 1950s and 1960s led to California's "Silicon Valley" becoming a hotbed of electronics innovation. In his later life, Shockley was a professor at Stanford, and he also became a staunch advocate of eugenics.
When World War II broke out, Shockley became involved in radar research at the labs in Whippany, New Jersey. In May 1942 he took leave from Bell Labs to become a research director at Columbia University's Anti-Submarine Warfare Operations Group. This involved devising methods for countering the tactics of submarines with improved convoying techniques, optimizing depth charge patterns, and so on. This project required frequent trips to the Pentagon and Washington, where Shockley met many high ranking officers and government officials. In 1944 he organized a training program for B-29 bomber pilots to use new radar bomb sights. In late 1944 he took a three month tour to bases around the world to assess the results. For this project, Secretary of War Robert Patterson awarded Shockley the Medal of Merit on October 17, 1946.
In July 1945, the War Department asked Shockley to prepare a report on the question of probable casualties from an invasion of the Japanese mainland. Shockley concluded:
This prediction influenced the decision for the atomic bombings of Hiroshima and Nagasaki to force Japan to surrender without an invasion.
December 1947 was Bell Labs' "Miracle Month," when Bardeen and Brattain -- working without Shockley -- succeeded in creating a point-contact transistor that achieved amplification. By the next month, Bell Lab's patent attorneys started to work on the patent applications.
Bell Labs attorneys soon discovered that Shockley's field effect principle had been anticipated and patented in 1930 by Julius Lilienfeld, who filed his MESFET-like patent in Canada already on October 22, 1925. Although the patent appeared "breakable" (it could not work) the patent attorneys based one of its four patent applications only on the Bardeen-Brattain point contact design. Three others submitted at the same time covered the electrolyte-based transistors with Bardeen, Gibney and Brattain as the inventors. Shockley's name was not on any of these patent applications. This angered Shockley, who thought his name should also be on the patents because the work was based on his field effect idea. He even made efforts to have the patent written only in his name, and told Bardeen and Brattain of his intentions.
At the same time he secretly continued his own work to build a different sort of transistor based on junctions instead of point contacts; he expected this kind of design would be more likely to be viable commercially. Shockley worked furiously on his magnum opus, Electrons and Holes in Semiconductors which was finally published as a 558 page treatise in 1950. In it, Shockley worked out the critical ideas of drift and diffusion and the differential equations that govern the flow of electrons in solid state crystals. Shockley's diode equation is also described. This seminal work became the "bible" for an entire generation of scientists working to develop and improve new variants of the transistor and other devices based on semiconductors.
Shockley was dissatisfied with certain parts of the explanation for how the point contact transistor worked and conceived of the possibility of minority carrier injection. This led Shockley to ideas for what he called a "sandwich transistor." This resulted in the junction transistor, which was announced at a press conference on July 4, 1951. Shockley obtained a patent for this invention on September 25, 1951. Different fabrication methods for this device were developed but the "diffused-base" method became the method of choice for many applications. It soon eclipsed the point contact transistor, and it and its offspring became overwhelmingly dominant in the marketplace for many years. Shockley continued as a group head to lead much of the effort at Bell Labs to improve it and its fabrication for two more years.
In 1951, he was elected a member of the National Academy of Sciences (NAS). He was forty-one years old; this was rather young for such an election. Two years later, he was chosen as the recipient of the prestigious Comstock Prize for Physics by the NAS, and was the recipient of many other awards and honors.
The ensuing publicity generated by the "invention of the transistor" often thrust Shockley to the fore, much to the chagrin of Bardeen and Brattain. Bell Labs management, however, consistently presented all three inventors as a team. Shockley eventually infuriated and alienated Bardeen and Brattain, and he essentially blocked the two from working on the junction transistor. Bardeen began pursuing a theory for superconductivity and left Bell Labs in 1951. Brattain refused to work with Shockley further and was assigned to another group. Neither Bardeen nor Brattain had much to do with the development of the transistor beyond the first year after its invention.
Shockley's abrasive management style caused him to be passed over for executive promotion at Bell Labs, which also felt he was a greater asset as a research scientist and theorist. Shockley wanted the power and profit he felt he deserved. He took a leave from Bell Labs in 1953 and moved back to the California Institute of Technology (Caltech) for four months as a visiting professor.
"His way" could generally be summed up as "domineering and increasingly paranoid". In one famous incident, he claimed that a secretary's cut thumb was the result of a malicious act and he demanded lie detector tests to find the culprit. It was later demonstrated the cut was due to a broken thumbtack on the office door, and from that point the research staff was increasingly hostile. Meanwhile, his demands to create a new and technically difficult device (originally called a Shockley diode and now known as the thyristor), meant that the project was moving very slowly.
Shockley separated from his wife Jean in the spring of 1954, finally divorcing her in the summer of 1954. Shortly after forming the company, on November 23, 1955, Shockley married Emmy Lanning, a teacher of psychiatric nursing from upstate New York. They had a very happy marriage that lasted until his death in 1989.
Shockley was a co-recipient of the Nobel Prize in physics in 1956, along with Bardeen and Brattain. In his Nobel lecture, he gave full credit to Brattain and Bardeen as the inventors of the point-contact transistor. The three of them, together with wives and guests, had a rather raucous late-night champagne-fueled party to celebrate together.
In late 1957, eight of Shockley's researchers, who called themselves "the Traitorous Eight," resigned after Shockley decided not to continue research into silicon-based semiconductors.
Several of the eight met with Sherman Fairchild and described the situation, and the eight started Fairchild Semiconductor after being given seed capital from Fairchild Camera and Instrument Corporation to form a semiconductor division. Among the "Traitorous Eight" were Robert Noyce and Gordon E. Moore, who themselves would leave Fairchild to create Intel. Other offspring companies of Fairchild Semiconductor include National Semiconductor and Advanced Micro Devices.
While Shockley was still trying to get his three-state device to work, Fairchild and Texas Instruments both introduced the first integrated circuits, making Shockley's work in that area essentially superfluous.
He was an atheist, and never attended church.
Shockley's last patent was granted in 1968, for a rather complex semiconductor device.
Late in his life, Shockley became intensely interested in questions of race, intelligence and eugenics. He thought this work was important to the genetic future of the human species, and came to describe it as the most important work of his career, even though expressing such politically unpopular views risked damaging his reputation. When asked why he seemed to take positions associated with both the political right and left, Shockley explained that his goal was "the application of scientific ingenuity to the solution of human problems.
Shockley believed that the higher rate of reproduction among the less intelligent was having a dysgenic effect, and that a drop in average intelligence would ultimately lead to a decline in civilization. Shockley advocated that the scientific community should seriously investigate questions of heredity, intelligence and demographic trends, and suggest policy changes if he was proven right.
Although Shockley was concerned about both black and white dysgenic effects, he found the situation among blacks more disastrous. While unskilled whites had 3.7 children on average versus an average of 2.3 children for skilled whites, Shockley found from the 1970 Census Bureau reports that unskilled blacks had 5.4 children versus 1.9 for the skilled blacks. Shockley reasoned that because intelligence (like most traits) is inherited, the black population would, over time, become much less intelligent countering all the gains that had been made by the Civil Rights movement. Shockley's published writings and lectures to scientific organizations on this topic, such as the National Academy of Sciences, were partly based on the research of Berkeley psychologist Arthur Jensen, Cyril Burt and H. J. Eysenck. Shockley also proposed that individuals with IQs below 100 be paid to undergo voluntary sterilization.
He donated sperm to the Repository for Germinal Choice, a sperm bank founded by Robert Klark Graham in hopes of spreading humanity's best genes. The bank, called by the media the "Nobel Prize sperm bank," claimed to have three Nobel Prize-winning donors, though Shockley was the only one to publicly acknowledge his donation to the sperm bank. However, Shockley's views about the genetic superiority of whites over blacks brought the Repository for Germinal Choice notable negative publicity and discouraged other Nobel Prize winners from donating sperm.
In 1981 he filed a libel suit against the Atlanta Constitution after a reporter called him a "Hitlerite" and compared his racial views to the Nazis. Shockley won the suit, but received only US$1 in damages. He was represented by Murray M. Silver, Esq., Attorney at Law, Atlanta, Georgia. See: Time Magazine, September 24, 1984, Page 62.
In his later years Shockley took several precautions to improve his interactions with the media, to little avail. He taped his telephone conversations with reporters, and then sent the transcript to the reporter by registered mail. At one point he toyed with the idea of making them take a simple quiz on his work before discussing the subject with them.
Shockley has been described as a racist, white supremacist, and scientific racist. Eugenics advocate Ernst Mayr, in a letter to Francis Crick, wrote:
If I may summarize my own viewpoint, it is that positive eugenics is of great importance for the future of mankind and that all roadblocks must be removed that stand in the way of intensifying research in this area. Shockley with his racist views is unfortunately the worst roadblock at this time, at least in this country; hence, his sharp rejection by some of us who are very much in favor of positive eugenics. I do hope I have been able to shed light on our side of the argument.Epps argued that William Shockley's position lends itself to racist interpretations. Scully called him William Shockley, the notorious eugenicist and scientific racist. Daniel J. Kevles mentioned he invited ridicule as a racist and biological ignoramus. Roger Pearson, another eugenicist, has defended Shockley, arguing that Shockley, being one of the first to break the taboo on frank discussion of racial differences, has been demonized by the popular media who created an unbalanced picture of his beliefs and opinions.
By the time of his death he was almost completely estranged from most of his friends and family, except his wife. His children are reported to have learned of his death only through the print media.
A group of about 30 colleagues, who have met on and off since 1956, met at Stanford in 2002 to reminisce about their time with Shockley and his central role in sparking the information technology revolution, its organizer saying "Shockley is the man who brought silicon to Silicon Valley.
