2 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.

3 Noyce, Robert
SUBJECT AREA: Electronics and information technology[br]b. 12 December 1927 Burlington, Iowa, USA[br]American engineer responsible for the development of integrated circuits and the microprocessor chip.[br]Noyce was the son of a Congregational minister whose family, after a number of moves, finally settled in Grinnell, some 50 miles (80 km) east of Des Moines, Iowa. Encouraged to follow his interest in science, in his teens he worked as a baby-sitter and mower of lawns to earn money for his hobby. One of his clients was Professor of Physics at Grinnell College, where Noyce enrolled to study mathematics and physics and eventually gained a top-grade BA. It was while there that he learned of the invention of the transistor by the team at Bell Laboratories, which included John Bardeen, a former fellow student of his professor. After taking a PhD in physical electronics at the Massachusetts Institute of Technology in 1953, he joined the Philco Corporation in Philadelphia to work on the development of transistors. Then in January 1956 he accepted an invitation from William Shockley, another of the Bell transistor team, to join the newly formed Shockley Transistor Company, the first electronic firm to set up shop in Palo Alto, California, in what later became known as "Silicon Valley".From the start things at the company did not go well and eventually Noyce and Gordon Moore and six colleagues decided to offer themselves as a complete development team; with the aid of the Fairchild Camera and Instrument Company, the Fairchild Semiconductor Corporation was born. It was there that in 1958, contemporaneously with Jack K. Wilby at Texas Instruments, Noyce had the idea for monolithic integration of transistor circuits. Eventually, after extended patent litigation involving study of laboratory notebooks and careful examination of the original claims, priority was assigned to Noyce. The invention was most timely. The Apollo Moon-landing programme announced by President Kennedy in May 1961 called for lightweight sophisticated navigation and control computer systems, which could only be met by the rapid development of the new technology, and Fairchild was well placed to deliver the micrologic chips required by NASA.In 1968 the founders sold Fairchild Semicon-ductors to the parent company. Noyce and Moore promptly found new backers and set up the Intel Corporation, primarily to make high-density memory chips. The first product was a 1,024-bit random access memory (1 K RAM) and by 1973 sales had reached $60 million. However, Noyce and Moore had already realized that it was possible to make a complete microcomputer by putting all the logic needed to go with the memory chip(s) on a single integrated circuit (1C) chip in the form of a general purpose central processing unit (CPU). By 1971 they had produced the Intel 4004 microprocessor, which sold for US$200, and within a year the 8008 followed. The personal computer (PC) revolution had begun! Noyce eventually left Intel, but he remained active in microchip technology and subsequently founded Sematech Inc.[br]Principal Honours and DistinctionsFranklin Institute Stuart Ballantine Medal 1966.
