15 Strachey, Christopher
SUBJECT AREA: Electronics and information technology[br]b. 16 November 1916 Englandd. 18 May 1975 Oxford, England[br]English physicist and computer engineer who proposed time-sharing as a more efficient means of using a mainframe computer.[br]After education at Gresham's School, London, Strachey went to King's College, Cambridge, where he completed an MA. In 1937 he took up a post as a physicist at the Standard Telephone and Cable Company, then during the Second World War he was involved in radar research. In 1944 he became an assistant master at St Edmunds School, Canterbury, moving to Harrow School in 1948. Another change of career in 1951 saw him working as a Technical Officer with the National Research and Development Corporation, where he was involved in computer software and hardware design. From 1958 until 1962 he was an independent consultant in computer design, and during this time (1959) he realized that as mainframe computers were by then much faster than their human operators, their efficiency could be significantly increased by "time-sharing" the tasks of several operators in rapid succession. Strachey made many contributions to computer technology, being variously involved in the design of the Manchester University MkI, Elliot and Ferranti Pegasus computers. In 1962 he joined Cambridge University Mathematics Laboratory as a senior research fellow at Churchill College and helped to develop the programming language CPL. After a brief period as Visiting Lecturer at the Massachusetts Institute of Technology, he returned to the UK in 1966 as Reader in Computation and Fellow of Wolfeon College, Oxford, to establish a programming research group. He remained there until his death.[br]Principal Honours and DistinctionsDistinguished Fellow of the British Computer Society 1972.Bibliography1961, with M.R.Wilkes, "Some proposals for improving the efficiency of Algol 60", Communications of the ACM 4:488.1966, "Systems analysis and programming", Scientific American 25:112. 1976, with R.E.Milne, A Theory of Programming Language Semantics.Further ReadingJ.Alton, 1980, Catalogue of the Papers of C.

16 Kompfner, Rudolph
[br]b. 16 May 1909 Vienna, Austriad. 3 December 1977 Stanford, California, USA[br]Austrian (naturalized English in 1949, American in 1957) electrical engineer primarily known for his invention of the travelling-wave tube.[br]Kompfner obtained a degree in engineering from the Vienna Technische Hochschule in 1931 and qualified as a Diplom-Ingenieur in Architecture two years later. The following year, with a worsening political situation in Austria, he moved to England and became an architectural apprentice. In 1936 he became Managing Director of a building firm owned by a relative, but at the same time he was avidly studying physics and electronics. His first patent, for a television pick-up device, was filed in 1935 and granted in 1937, but was not in fact taken up. In June 1940 he was interned on the Isle of Man, but as a result of a paper previously sent by him to the Editor of Wireless Engineer he was released the following December and sent to join the group at Birmingham University working on centimetric radar. There he worked on klystrons, with little success, but as a result of the experience gained he eventually invented the travelling-wave tube (TWT), which was based on a helical transmission line. After disbandment of the Birmingham team, in 1946 Kompfner moved to the Clarendon Laboratory at Oxford and in 1947 he became a British subject. At the Clarendon Laboratory he met J.R. Pierce of Bell Laboratories, who worked out the theory of operation of the TWT. After gaining his DPhil at Oxford in 1951, Kompfner accepted a post as Principal Scientific Officer at Signals Electronic Research Laboratories, Baldock, but very soon after that he was invited by Pierce to work at Bell on microwave tubes. There, in 1952, he invented the backward-wave oscillator (BWO). He was appointed Director of Electronics Research in 1955 and Director of Communications Research in 1962, having become a US citizen in 1957. In 1958, with Pierce, he designed Echo 1, the first (passive) satellite, which was launched in August 1960. He was also involved with the development of Telstar, the first active communications satellite, which was launched in 1962. Following his retirement from Bell in 1973, he continued to pursue research, alternately at Stanford, California, and Oxford, England.[br]Principal Honours and DistinctionsPhysical Society Duddell Medal 1955.

17 Townes, Charles Hard
SUBJECT AREA: Electronics and information technology[br]b. 28 July 1915 Greenville, South Carolina, USA[br]American physicist who developed the maser and contributed to the development of the laser.[br]Charles H.Townes entered Furman University, Greenville, at the early age of 16 and in 1935 obtained a BA in modern languages and a BS in physics. After a year of postgraduate study at Duke University, he received a master's degree in physics in 1936. He then went on to the California Institute of Technology, where he obtained a PhD in 1939. From 1939 to 1947 he worked at the Bell Telephone Laboratories, mainly on airborne radar, although he also did some work on radio astronomy. In 1948 he joined Columbia University as Associate Professor of Physics and in 1950 was appointed a full professor. He was Director of the University's Radiation Laboratory from 1950 to 1952, and from 1952 to 1955 he was Chairman of the Physics Department.To meet the need for an oscillator generating very short wavelength electromagnetic radiation, Townes in 1951 realized that use could be made of the different natural energy levels of atoms and molecules. The practical application of this idea was achieved in his laboratory in 1953 using ammonia gas to make the device known as a maser (an acronym of microwave amplification by stimulated emission of radiation). The maser was developed in the next few years and in 1958, in a joint paper with his brother-in-law Arthur L. Schawlow, Townes suggested the possibility of a further development into optical frequencies or an optical maser, later known as a laser (an acronym of light amplification by stimulated emission of radiation). Two years later the first such device was made by Theodore H. Maiman.In 1959 Townes was given leave from Columbia University to serve as Vice-President and Director of Research at the Institute for Defense Analyses until 1961. He was then appointed Provost and Professor of Physics at the Massachusetts Institute of Technology. In 1967 he became University Professor of Physics at the University of California, where he has extended his research interests in the field of microwave and infra-red astronomy. He is a member of the National Academy of Sciences, the Institute of Electrical and Electronics Engineers and the American Astronomical Society.[br]Principal Honours and DistinctionsNobel Prize for Physics 1964. Foreign Member, Royal Society of London. President, American Physical Society 1967. Townes has received many awards from American and other scientific societies and institutions and honorary degrees from more than twenty universities.BibliographyTownes is the author of many scientific papers and, with Arthur L.Schawlow, ofMicrowave Spectroscopy (1955).1980, entry, McGraw-Hill Modern Scientists and Engineers, Part 3, New York, pp. 227– 8 (autobiography).1991, entry, The Nobel Century, London, p. 106 (autobiography).Further ReadingT.Wasson (ed.), 1987, Nobel Prize Winners, New York, pp. 1,071–3 (contains a short biography).RTS -
18 Randall, Sir John Turton
SUBJECT AREA: Medical technology[br]b. 23 March 1905 Newton-le-Willows, Lancashire, Englandd. 16 June 1984 Edinburgh, Scotland[br]English physicist and biophysicist, primarily known for the development, with Boot of the cavity magnetron.[br]Following secondary education at Ashton-inMakerfield Grammar School, Randall entered Manchester University to read physics, gaining a first class BSc in 1925 and his MSc in 1926. From 1926 to 1937 he was a research physicist at the General Electric Company (GEC) laboratories, where he worked on luminescent powders, following which he became Warren Research Fellow of the Royal Society at Birmingham University, studying electronic processes in luminescent solids. With the outbreak of the Second World War he became an honorary member of the university staff and transferred to a group working on the development of centrimetric radar. With Boot he was responsible for the development of the cavity magnetron, which had a major impact on the development of radar.When Birmingham resumed its atomic research programme in 1943, Randall became a temporary lecturer at the Cavendish Laboratory in Cambridge. The following year he was appointed Professor of Natural Philosophy at the University of St Andrews, but in 1946 he moved again to the Wheatstone Chair of Physics at King's College, London. There his developing interest in biophysical research led to the setting up of a multi-disciplinary group in 1951 to study connective tissues and other biological components, and in 1950– 5 he was joint Editor of Progress in Biophysics. From 1961 until his retirement in 1970 he was Professor of Biophysics at King's College and for most of that time he was also Chairman of the School of Biological Sciences. In addition, for many years he was honorary Director of the Medical Research Council Biophysics Research Unit.After he retired he returned to Edinburgh and continued to study biological problems in the university zoology laboratory.[br]Principal Honours and DistinctionsKnighted 1962.

19 Williams, Sir Frederic Calland
SUBJECT AREA: Electronics and information technology[br]b. 26 June 1911 Stockport, Cheshire, Englandd. 11 August 1977 Prestbury, Cheshire, England[br]English electrical engineer who invented the Williams storage cathode ray tube, which was extensively used worldwide as a data memory in the first digital computers.[br]Following education at Stockport Grammar School, Williams entered Manchester University in 1929, gaining his BSc in 1932 and MSc in 1933. After a short time as a college apprentice with Metropolitan Vickers, he went to Magdalen College, Oxford, to study for a DPhil, which he was awarded in 1936. He returned to Manchester University that year as an assistant lecturer, gaining his DSc in 1939. Following the outbreak of the Second World War he worked for the Scientific Civil Service, initially at the Bawdsey Research Station and then at the Telecommunications Research Establishment at Malvern, Worcestershire. There he was involved in research on non-incandescent amplifiers and diode rectifiers and the development of the first practical radar system capable of identifying friendly aircraft. Later in the war, he devised an automatic radar system suitable for use by fighter aircraft.After the war he resumed his academic career at Manchester, becoming Professor of Electrical Engineering and Director of the University Electrotechnical Laboratory in 1946. In the same year he succeeded in developing a data-memory device based on the cathode ray tube, in which the information was stored and read by electron-beam scanning of a charge-retaining target. The Williams storage tube, as it became known, not only found obvious later use as a means of storing single-frame, still television images but proved to be a vital component of the pioneering Manchester University MkI digital computer. Because it enabled both data and program instructions to be stored in the computer, it was soon used worldwide in the development of the early stored-program computers.[br]Principal Honours and DistinctionsKnighted 1976.

20 Varian, Russell Harrison
[br]b. 24 April 1898 Washington, DC, USAd. 28 July 1959 Juneau, Alaska, USA[br]American physicist who, with his brother Sigurd Varian and others, developed the klystron.[br]After attending schools in Palo Alto and Halcyon, Russell Varian went to Stanford University, gaining his BA in 1925 and his MA in 1927 despite illness and being dyslexic. His family being in need of financial help, he first worked for six months for Bush Electric in San Francisco and then for an oil company in Texas, returning to San Francisco in 1930 to join Farnsworth's Television Laboratory. After a move to Philadelphia, in 1933 the laboratory closed and Russell tried to take up a PhD course at Stanford but was rejected, so he trained as a teacher. However, although he did some teaching at Stanford it was not to be his career, for in 1935 he joined his brothers Sigurd and Eric in the setting up of a home laboratory.There, with William Hansen, a former colleague of Russell's at Stanford, they worked on the development of microwave oscillators, based on some of the latter's ideas. By 1937 they had made sufficient progress on an electron velocity-bunching tube, which they called the klystron, to obtain an agreement with the university to provide laboratory facilities in return for a share of any proceeds. By August that year they were able to produce continuous power at a wavelength of 13 cm. Clearly needing greater resources to develop and manufacture the tube, and with a possible war looming, a deal was struck with the Sperry Gyroscope Company to finance the work, which was transferred to the East Coast.In 1946, after the death of his first wife, Russell returned to Palo Alto, and in 1948 the brothers and Hansen founded Varian Associates to make microwave tubes for transmitters and linear accelerators and nuclear magnetic-resonance detectors. Subsequent research also resulted in the development of a satellite-borne magnetometer for measuring the earth's magnetic field.[br]Principal Honours and DistinctionsHonorary DSc Brooklyn Polytechnic Institute 1943.
