William Bradford Shockley (Template:IPAc-en Template:Respell;<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> February 13, 1910 – August 12, 1989) was an American solid-state physicist, electrical engineer, and inventor. He was the manager of a research group at Bell Labs that included John Bardeen and Walter Houser Brattain. The three scientists were jointly awarded the 1956 Nobel Prize in Physics for "their researches on semiconductors and their discovery of the transistor effect".<ref name=":7">Template:Cite journal</ref>

Partly as a result of Shockley's attempts to commercialize a new transistor design in the 1950s and 1960s, California's Silicon Valley became a hotbed of electronics innovation. He recruited brilliant employees, but quickly alienated them with his autocratic and erratic management; they left and founded major companies in the industry.<ref name=":10" />

In his later life, while a professor of electrical engineering at Stanford University and afterward, Shockley became known as a racist and eugenicist.<ref name="latimesobit" /><ref name="NYTimesobit" /><ref name="PhysicsTodayobit" /><ref name=":6">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref>Template:Cite journal</ref> Template:TOClimit

Early life and educationEdit

Shockley was born to American parents in London on February 13, 1910, and was raised in his family's hometown of Palo Alto, California, from the age of three.<ref name="IREProceedings1952" /> His father, William Hillman Shockley, was a mining engineer who speculated in mines for a living and spoke eight languages. His mother, May (née Bradford), grew up in the American West, graduated from Stanford University and became the first female U.S. Deputy mining surveyor.<ref name="Shurkin2006p3" /> Shockley was homeschooled up to the age of eight, due to his parents' dislike of public schools as well as Shockley's habit of violent tantrums.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> Shockley learned a little physics at a young age from a neighbor who was a Stanford physics professor.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> Shockley spent two years at Palo Alto Military Academy, then briefly enrolled in the Los Angeles Coaching School to study physics and later graduated from Hollywood High School in 1927.<ref name=":1">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref>Template:Cite book</ref>

Shockley earned his Bachelor of Science degree from Caltech in 1932 and a PhD from MIT in 1936. The title of his doctoral thesis was Electronic Bands in Sodium Chloride, a topic suggested by his thesis advisor, John C. Slater.<ref name="Shurkin2006pp38–39" />

CareerEdit

Shockley was one of the first recruits to Bell Labs by Mervin Kelly, who became director of research at the company in 1936 and focused on hiring solid-state physicists.<ref name=":5" /> Shockley joined a group headed by Clinton Davisson in Murray Hill, New Jersey.<ref>Template:Cite book</ref> Executives at Bell Labs had theorized that semiconductors may offer solid-state alternatives to the vacuum tubes used throughout Bell's nationwide telephone system. Shockley conceived a number of designs based on copper-oxide semiconductor materials, and with Walter Brattain unsuccessfully attempted to create a prototype in 1939.<ref name=":5">Transistor – Innovation at Bell Labs Encyclopedia Britannica</ref>

Shockley published a number of fundamental papers on solid state physics in Physical Review. In 1938, he received his first patent, "Electron Discharge Device", on electron multipliers.<ref name="Shurkin2006p48" />

When World War II broke out, Shockley's prior research was interrupted and he became involved in radar research in Manhattan (New York City). In May 1942, he took leave from Bell Labs to become a research director at Columbia University's Anti-Submarine Warfare Operations Group.<ref>Broken Genius p. 65–67</ref> This involved devising methods for countering the tactics of submarines with improved convoying techniques, optimizing depth charge patterns, and so on. Shockley traveled frequently to the Pentagon and Washington to meet high-ranking officers and government officials.<ref>Template:Cite book</ref>

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 for Merit on October 17, 1946.<ref name="Shurkin2006p85"/>

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 report influenced the decision of the United States to drop atomic bombs on Hiroshima and Nagasaki, which preceded the surrender of Japan.<ref>Template:Cite journal</ref>

Shockley was the first physicist to propose a log-normal distribution to model the creation process for scientific research papers.<ref>The Artful Universe by John D. Barrow, Clarendon Press, Oxford, 1995, p. 239</ref>

Development of the transistorEdit

Shortly after the war ended in 1945, Bell Labs formed a solid-state physics group, led by Shockley and chemist Stanley Morgan, which included John Bardeen, Walter Brattain, physicist Gerald Pearson, chemist Robert Gibney, electronics expert Hilbert Moore, and several technicians. Their assignment was to seek a solid-state alternative to fragile glass vacuum tube amplifiers. First attempts were based on Shockley's ideas about using an external electrical field on a semiconductor to affect its conductivity. These experiments failed every time in all sorts of configurations and materials. The group was at a standstill until Bardeen suggested a theory that invoked surface states that prevented the field from penetrating the semiconductor. The group changed its focus to study these surface states and they met almost daily to discuss the work. The group had excellent rapport and freely exchanged ideas.<ref>Brattain quoted in Crystal Fire p. 127</ref>

By the winter of 1946 they had enough results that Bardeen submitted a paper on the surface states to Physical Review. Brattain started experiments to study the surface states through observations made while shining a bright light on the semiconductor's surface. This led to several more papers (one of them co-authored with Shockley), which estimated the density of the surface states to be more than enough to account for their failed experiments. The pace of the work picked up significantly when they started to surround point contacts between the semiconductor and the conducting wires with electrolytes. Moore built a circuit that allowed them to vary the frequency of the input signal easily. Finally they began to get some evidence of power amplification when Pearson, acting on a suggestion by Shockley, put a voltage on a droplet of glycol borate placed across a p–n junction.<ref name="Crystal Fire p. 132">Crystal Fire p.132</ref>

Bell Labs' attorneys soon discovered Shockley's field effect principle had been anticipated and devices based on it patented in 1930 by Julius Lilienfeld, who filed his MESFET-like patent in Canada on October 22, 1925.<ref>Template:Patent</ref><ref>Lilienfeld Template:Webarchive</ref> 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 first) covered the electrolyte-based transistors with Bardeen, Gibney and Brattain as the inventors.Template:Citation needed

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.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

Shockley, angered by not being included on the patent applications, 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 commercially viable. The point contact transistor, he believed, would prove to be fragile and difficult to manufacture. Shockley was also dissatisfied with certain parts of the explanation for how the point contact transistor worked and conceived of the possibility of minority carrier injection.

On February 13, 1948, another team member, John N. Shive, built a point contact transistor with bronze contacts on the front and back of a thin wedge of germanium, proving that holes could diffuse through bulk germanium and not just along the surface as previously thought.<ref name="crystal-fire">Template:Cite book</ref>Template:Rp<ref name="True Genius">Template:Cite book

  • Template:Cite magazine</ref>Template:Rp Shive's invention sparked<ref name="Brittain1984p1695" /> Shockley's invention of the junction transistor.<ref name="crystal-fire"/>Template:Rp A few months later he invented an entirely new, considerably more robust, type of transistor with a layer or 'sandwich' structure. This structure went on to be used for the vast majority of all transistors into the 1960s, and evolved into the bipolar junction transistor. Shockley later described the workings of the team as a "mixture of cooperation and competition". He also said that he kept some of his own work secret until his "hand was forced" by Shive's 1948 advance.<ref name=":3">Template:Cite news</ref> Shockley worked out a rather complete description of what he called the "sandwich" transistor, and a first proof of principle was obtained on April 7, 1949.

Meanwhile, Shockley worked on his magnum opus, Electrons and Holes in Semiconductors which was published as a 558-page treatise in 1950. The tome included Shockley's 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 reference text for other scientists working to develop and improve new variants of the transistor and other devices based on semiconductors.<ref>Broken Genius, p 121-122</ref>

This resulted in his invention of the bipolar "junction transistor", which was announced at a press conference on July 4, 1951.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

In 1951, he was elected to 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<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> 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. Though Shockley would correct the record where reporters gave him sole credit for the invention,<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> he 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.<ref>Crystal Fire p. 278</ref>

Shockley left Bell Labs around 1953 and took a job at Caltech.<ref name=":4" />

Shockley, Bardeen and Brattain received the Nobel Prize in Physics in 1956.<ref name=":7" />

Shockley SemiconductorEdit

{{#invoke:Labelled list hatnote|labelledList|Main article|Main articles|Main page|Main pages}} In 1956, Shockley started Shockley Semiconductor Laboratory in Mountain View, California, which was close to his elderly mother in Palo Alto, California.<ref>Template:Cite news</ref><ref>Template:Cite news</ref> The company, a division of Beckman Instruments, Inc., was the first establishment working on silicon semiconductor devices in what came to be known as Silicon Valley.

Shockley recruited brilliant employees to his company, but alienated them by undermining them relentlessly.<ref name=":10">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref name=":9">Template:Cite news</ref> "He may have been the worst manager in the history of electronics", according to his biographer Joel Shurkin.<ref name=":9" /><ref name=":10" /> Shockley was autocratic, domineering, erratic, hard-to-please, and increasingly paranoid.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref name=":8" /> In one well-known incident, he demanded lie detector tests to find the "culprit" after a company secretary suffered a minor cut.<ref name=":8">Crystal Fire p. 247</ref> In late 1957, eight of Shockley's best researchers, who would come to be known as the "traitorous eight", resigned after Shockley decided not to continue research into silicon-based semiconductors.<ref name="Goodheart2006" /><ref name=":4" /> They went on to form Fairchild Semiconductor, a loss from which Shockley Semiconductor never recovered and which led to its purchase by another company three years later. Over the course of the next 20 years, more than 65 new enterprises would end up having employee connections back to Fairchild.<ref name="NetValley">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

A group of about thirty colleagues have met on and off since 1956 to reminisce about their time with Shockley, "the man who brought silicon to Silicon Valley", as the group's organizer said in 2002.<ref>Template:Cite press release</ref>

Racist and eugenicist viewsEdit

Template:See also After Shockley left his role as director of Shockley Semiconductor, he joined Stanford University, where he was appointed the Alexander M. Poniatoff Professor of Engineering and Applied Science in 1963, a position which he held until he retired as a professor emeritus in 1975.<ref>Crystal Fire p. 277</ref>

In the last two decades of his life, Shockley, who had no degree in genetics, became widely known for his extreme views on race and human intelligence, and his advocacy of eugenics.<ref name="latimesobit" /><ref name=":6" /> As described by his Los Angeles Times obituary, "He went from being a physicist with impeccable academic credentials to amateur geneticist, becoming a lightning rod whose views sparked campus demonstrations and a cascade of calumny". He thought his work was important to the future of humanity and he also described it as the most important aspect of his career. He argued that a higher rate of reproduction among purportedly less intelligent people was having a dysgenic effect, and argued that a drop in average intelligence would lead to a decline in civilization. He also claimed that black people were genetically and intellectually inferior to white people.<ref name="latimesobit" />

Shockley's biographer Joel Shurkin notes that for much of Shockley's life in the racially segregated United States of the time, he had almost no contact with black people.Template:Sfn In a debate with psychiatrist Frances Cress Welsing and on Firing Line with William F. Buckley Jr., Shockley argued, "My research leads me inescapably to the opinion that the major cause of the American Negro's intellectual and social deficits is hereditary and racially genetic in origin and, thus, not remediable to a major degree by practical improvements in the environment".<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}Template:Cbignore</ref>

Shockley was one of the race theorists who received money from the Pioneer Fund, and at least one donation to him came from its founder, the eugenicist Wickliffe Draper.<ref name=":2">Template:Cite book</ref>Template:Sfn Shockley proposed that individuals with IQs below 100 should be paid to undergo voluntary sterilization, $1,000 for each of their IQ points under 100.<ref name="latimesobit">Template:Cite news</ref> This proposal led to the University of Leeds to withdraw its offer of an honorary degree to him.<ref name="latimesobit" /> Anthropologist and far-right activist Roger Pearson defended Shockley in a self-published book co-authored with Shockley.<ref>Pearson, Roger (1992). Shockley on Eugenics and Race, pg. 15–49. Scott-Townsend Publishers. Template:ISBN</ref> In 1973, University of Wisconsin–Milwaukee professor Edgar G. Epps argued that "William Shockley's position lends itself to racist interpretations".<ref name=":12">Template:Cite journal</ref> The Southern Poverty Law Center describes Shockley as a white nationalist who failed to produce evidence for his eugenic theories amidst "near-universal acknowledgement that his work was that of a racist crank".<ref name=":0" /> The science writer Angela Saini describes Shockley as having been "a notorious racist".<ref name=":2" />

Shockley insisted that he was not a racist.<ref name=":12" /><ref>Template:Cite news</ref> He wrote that his findings do not support white supremacy, instead claiming that East Asians and Jews fare better than whites intellectually.<ref name=":12" /> In 1973, Edgar Epps wrote that "I am pleased that Professor Shockley is not an Aryan supremacist, but I would remind him that a theory espousing hereditary superiority of Orientals or Jews is just as racist in nature as the Aryan supremacy doctrine".<ref name=":12" />

Shockley's advocacy of eugenics triggered protests. In one incident, the science society Sigma Xi, fearing violence, canceled a 1968 convocation in Brooklyn where Shockley was scheduled to speak.Template:Sfn

In Atlanta in 1981, Shockley filed a libel suit against the Atlanta Constitution after a science writer, Roger Witherspoon, compared Shockley's advocacy of a voluntary sterilization program to Nazi human experimentation. The suit took three years to go to trial. Shockley won the suit but he only received one dollar in damages<ref>Template:Cite news</ref> and he did not receive any punitive damages. Shockley's biographer Joel Shurkin, a science writer on the staff of Stanford University during those years, sums this statement up by saying that it was defamatory, but Shockley's reputation was not worth much by the time the trial reached a verdict.<ref name="Shurkin2006pp259–260" /> Shockley taped his telephone conversations with reporters, transcribed them, and sent the transcripts to the reporters by registered mail. At one point, he toyed with the idea of making the reporters take a simple quiz on his work before he would discuss the subject matter of it with them. His habit of saving all of his papers (including laundry lists) provides abundant documentation on his life for researchers.<ref name="Shurkin2006p286" />

Shockley was a candidate for the Republican nomination in the 1982 United States Senate election in California. He ran on a single-issue platform of opposing the "dysgenic threat" that he alleged African-Americans and other groups posed.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref name=":0">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref>Template:Cite news</ref> He came in eighth place in the primary, receiving 8,308 votes and 0.37% of the vote.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> According to Shurkin, by this time, "His racism destroyed his credibility. Almost no one wanted to be associated with him, and many of those who were willing did him more harm than good".Template:Sfn

Foundation for Research and Education on Eugenics and DysgenicsEdit

Foundation for Research and Education on Eugenics and Dysgenics (FREED) was a non-profit organization founded in March 1970 in the United States formed to support the research of Shockley, who was the president of the foundation and R. Travis Osborne, a member.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref>Template:Cite journal</ref><ref name="Tucker 1994">Template:Cite book</ref> The foundation released newsletter 'FREED' and research papers at Stanford University.

The organization was founded according to its mission "solely for scientific and educational purposes related to human population and quality problems".<ref name="Tucker 1994" />

From 1969 to 1976, the Pioneer Fund allocated about $2.5 million (adjusted-for-inflation in 2023) to support Shockley's endeavors. This funding was distributed through grants to Stanford University for the exploration of "research into the factors which affect genetic potential" and also directly to FREED.<ref name="fighting-hate/extremist">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref>Template:Cite news</ref>

Via FREED, Shockley promoted his concept of a "Voluntary Sterilization Bonus Plan", proposing to compensate economically disadvantaged women for undergoing sterilization procedures.<ref name="fighting-hate/extremist" />

In 1970, Shockley listed former senator of Alaska Ernest Gruening as a director of FREED.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

Personal lifeEdit

At age 23 and while still a student, Shockley married Jean Bailey in August 1933. The couple had two sons and a daughter.<ref>A Science Odyssey: People and Discoveries: William Shockley PBS</ref> Shockley separated from her in 1953.<ref name=":4" /> He married Emily Lanning, a psychiatric nurse, in 1955; she helped him with some of his theories.<ref name=":4" /><ref>Template:Cite book</ref> Although one of his sons earned a PhD at Stanford University and his daughter graduated from Radcliffe College, Shockley believed his children "represent a very significant regression ... my first wife – their mother – had not as high an academic-achievement standing as I had".<ref name=latimesobit/>

Shockley was an accomplished rock climber, going often to the Shawangunks in the Hudson River Valley. His route across an overhang, known as "Shockley's Ceiling", is one of the classic climbing routes in the area.<ref name="Crystal Fire p. 132"/><ref>{{#invoke:citation/CS1|citation |CitationClass=web }} </ref> Mountain Project, a web-based climbing guidebook, changed the route's name to "The Ceiling" in 2020 due to Shockley's eugenics controversies.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> He was popular as a speaker, lecturer, and amateur magician. He once "magically" produced a bouquet of roses at the end of his address before the American Physical Society. He was also known in his early years for elaborate practical jokes.<ref>Crystal Fire p. 45</ref> He had a longtime hobby of raising ant colonies.<ref name=":1" />

Shockley 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 involvement.<ref>Template:Cite news</ref> However, Shockley's controversial views brought the Repository for Germinal Choice a degree of notoriety and may have discouraged other Nobel Prize winners from donating sperm.<ref>Template:Cite news</ref>

Shockley was unhappy in his life and was often psychologically and sometimes physically abusive toward his sons.<ref>Broken Genius p. 91–92</ref> On one occasion, he reportedly played Russian roulette on himself as part of a suicide attempt.<ref name=":4">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref>Broken Genius pp. 78</ref>

DeathEdit

Shockley died of prostate cancer in 1989 at the age of 79.<ref name="obit">Template:Cite news</ref> At the time of his death, he was estranged from most of his friends and family, except his second wife, the former Emmy Lanning (1913–2007). His children reportedly learned of his death by reading his obituary in the newspaper.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>Template:Bcn Shockley is interred at Alta Mesa Memorial Park in Palo Alto, California.
