Professional Experience: Bell Telephone Laboratories: member, Technical Staff, 1936- 1942 and 1945-1954, director, Transistor Physics Research Facility, 1954; director of research, Antisubmarine Warfare Operations Research Group, US Navy, 1942-1944; founder, Shockley Semiconductor Laboratory, 1954-1989; Stanford University: lecturer, 1958-1963, Alexander M. Poniatoff Professor of Engineering Science and Applied Science, 1963-1975, professor emeritus, 1975-1989. Honors and Awards: Nobel Prize in physics,1 1956. Co-inventor of the transistor in 1947 with John Bardeen and Walter Brattian, Shockley participated in one of the most important discoveries of the century. They applied for a patent in 1948; this device was described as a germanium “transfer resistance” unit, from which the name “transistor” was derived. Shockley continued his research on the device to create the germanium junction transfer transistor, which was much more reliable than the first unit. From this start he founded Shockley Semiconductor Laboratories in Santa Clara Valley in 1954. After he received the Nobel Prize in 1956, disenchantment with Shockley's management style and his propensity for pure research led to the defection of the “Fairchild Eight” in 1957, and the deterioration of his company. His controversial views on genetics and his racist theories have shocked the society around him, but he has continued his research into “grave world problems.” QUOTATION “The only heritage I can leave to Billy is the feeling of power and joy of responsibility for setting the world right on something.” (Shockley's mother, about her 8-year-old son) BIBLIOGRAPHY Biographical 1 Jointly with John Bardeen and Walter H.

  • 1947 Invention of the Point-Contact Transistor (Bell Telephone Laboratories) ~ Discrete Semiconductor/Others ~
    Semiconductor History Museum of Japan To search page 1947 Invention of the point-contact transistor (Bell Telephone Laboratories) ~ Discrete Semiconductor/Others ~ In December 1947, John Bardeen (1908-1991) and Walter Houser Brattain (1902-1987) of BTL (Bell Telephone Laboratories) found a phenomenon of current amplification in a pure Ge(germanium) single crystal, with a configuration of two gold needles placed in point contacts to the surface, closely with each other. When an electric current was passed in one needle, then an amplified current flow in the other needle was observed with the amplification of 100 times. This device was named "Transistor" by J.R. Pierce. This transistor invented at the beginning was called a point-contact transistor (Fig. 1). William Shockley (1910-1989) also at BTL found that the operation of this transistor was due to minority carrier injection and diffusion, and he developed this to the invention of the junction transistor (Fig. 2). It was in January 1948, five weeks after the invention of the point-contact transistor. Compared with the point-contact type, the junction transistor was capable of stable operation and was easy to mass-produce. After that, in April 1949 he further invented a transistor with a sandwich structure. It was a bipolar transistor (publicized in July 1951). Shockley, Bardeen, Brattain received the Nobel Prize in Physics in 1956. The group of Shockley, Bardeen, Brattain and others confirmed the operation of the point contact transistor using a Ge single crystal in December 1947. BTL published this invention in June 1948, and at the same time Western Electric, the manufacturing department of BTL, announced the plan to mass- produce transistors.

  • Playboy, but None So Adversarially As Physicist William Shockley
    WILLIAM SHOCKLEY August 1980 Interviewer: Syl Jones There have been a numberof Nobel Prize winners interviewed by pLayBoy, but none so adversarially as physicist William Shockley. One of the most controversial scien- tists of the twentieth century, Shockley was awarded the Nobel for his work in creat- ing the transistor, but spent most of the 1960s and 1970sin a field in which he was not educated—genetics—advancing theories thatin effect stipulate that blacks are infer- ior to whites. Even during the progressive Sixties, when radicals of every stripe were welcome to speak at American campuses, Shockley was one of the few whose very name could cause bannings and boycotts. Shockley’s notoriety would seem to have made him a perfect subject for a forum of last resort such as the Playboy Interview. But Shockley was in fact a problem to the magazine’s editors. It wasn’t just that the feature had a strong tradition in favor of civil rights (the first Playboy Interview was with a black man, Miles Davis, conducted by a black man, Alex Haley); it was that Shockley, unlike a cretin like Klan leader Shelton, made racist points that were not obviously refutable by laymen. Ordinary journalists were unpreparedto interrogate Shockley with enough expertise to put the complexities of race and genetics into perspective. Whena writer, journalist, and young playwright from Minneapolis named Syl Jones contacted Golson at PLAYBOY with the newsthat he not only wrote aboutscience but had made Shockley’s theories a personalfield of study, Golson felt a good oppor- tunity had arrived.
