71 Shockley, William Bradford
[br]b. 13 February 1910 London, Englandd. 12 August 1989, Palo Alto, California, USA.[br]American physicist who developed the junction transistor from the point contact transistor and was joint winner (with John Bardeen and Walter H. Brattain) of the 1956 Nobel Prize for physics.[br]The son of a mining engineer, Shockley graduated from the California Institute of Technology in 1932 and in 1936 obtained his PhD at the Massachusetts Institute of Technology. In that year, he joined the staff of Bell Telephone Laboratories.Since the early days of radio, crystals of silicon or similar materials had been used to rectify alternating current supply until these were displaced by thermionic valves or tubes. Shockley, with Bardeen and Brattain, found that crystals of germanium containing traces of certain impurities formed far better rectifiers than crystals of the material in its pure form. The resulting device, the transistor, could also be used to amplify the current; its name is derived from its ability to transfer current across a resistor. The transistor, being so much smaller than the thermionic valve which it replaced, led to the miniaturization of electronic appliances. Another advantage was that a transistorized device needed no period of warming up, such as was necessary with a thermionic valve before it would operate. The dispersal of the heat generated by a multiplicity of thermionic valves such as were present in early computers was another problem obviated by the advent of the transistor.Shockley was responsible for much development in the field of semiconductors. He was Deputy Director of the Weapons Systems Evaluation Group of the US Department of Defense (1954–5), and in 1963 he was appointed the first Poniatoff Professor of Engineering Science at Stanford University, California. During the late 1960s Shockley became a controversial figure for expressing his unorthodox views on genetics, such as that black people were inherently less intelligent than white people, and that the population explosion spread "bad" genes at the expense of "good" genes; he supported the idea of a sperm bank from Nobel Prize winners, voluntary sterilization and the restriction of interracial marriages.[br]Principal Honours and DistinctionsNobel Prize for Physics 1956.Further ReadingI.Asimov (ed.), 1982, Biographical Encyclopedia of Science and Technology, New York: Doubleday \& Co.IMcNBiographical history of technology > Shockley, William Bradford

73 Hetzel, Max
[br]b. 5 March 1921 Basle, Switzerland[br]Swiss electrical engineer who invented the tuning-fork watch.[br]Hetzel trained as an electrical engineer at the Federal Polytechnic in Zurich and worked for several years in the field of telecommunications before joining the Bulova Watch Company in 1950. At that time several companies were developing watches with electromagnetically maintained balances, but they represented very little advance on the mechanical watch and the mechanical switching mechanism was unreliable. In 1952 Hetzel started work on a much more radical design which was influenced by a transistorized tuning-fork oscillator that he had developed when he was working on telecommunications. Tuning forks, whose vibrations were maintained electromagnetically, had been used by scientists during the nineteenth century to measure small intervals of time, but Niaudet- Breguet appears to have been the first to use a tuning fork to control a clock. In 1866 he described a mechanically operated tuning-fork clock manufactured by the firm of Breguet, but it was not successful, possibly because the fork did not compensate for changes in temperature. The tuning fork only became a precision instrument during the 1920s, when elinvar forks were maintained in vibration by thermionic valve circuits. Their primary purpose was to act as frequency standards, but they might have been developed into precision clocks had not the quartz clock made its appearance very shortly afterwards. Hetzel's design was effectively a miniaturized version of these precision devices, with a transistor replacing the thermionic valve. The fork vibrated at a frequency of 360 cycles per second, and the hands were driven mechanically from the end of one of the tines. A prototype was working by 1954, and the watch went into production in 1960. It was sold under the tradename Accutron, with a guaranteed accuracy of one minute per month: this was a considerable improvement on the performance of the mechanical watch. However, the events of the 1920s were to repeat themselves, and by the end of the decade the Accutron was eclipsed by the introduction of quartz-crystal watches.[br]Principal Honours and DistinctionsNeuchâtel Observatory Centenary Prize 1958.
