10 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.

17 Carothers, Wallace Hume
[br]b. 27 April 1896 Burlington, Iowa, USAd. 29 April 1937 Philadelphia, Pennsylvania, USA[br]American chemist, inventor of nylon.[br]After graduating in chemistry, Carothers embarked on academic research at several universities, finally at Harvard University. His earliest published papers, from 1923, heralded the brilliance and originality of his later work. In 1928, Du Pont de Nemours persuaded him to forsake the academic world to lead their new organic-chemistry group in a programme of fundamental research at their central laboratories at Wilmington, Delaware. The next nine years were extraordinarily productive, yielding important contributions to theoretical organic chemistry and the foundation of two branches of chemical industry, namely the production of synthetic rubber and of wholly synthetic fibres.Carothers began work on high molecular weight substances yielding fibres and introduced polymerization by condensation: polymerization by addition was already known. He developed a clear understanding of the relation between the repeating structural units in a large molecule and its physical chemical properties. In 1931, Carothers found that chloroprene could be polymerized much faster than isoprene, the monomer in natural rubber. This process yielded polychloroprene or neoprene, a synthetic rubber with improved properties. Manufacture began the following year, and the material has continued to be used for speciality rubbers.There followed many publications announcing new condensations polymers. On 2 January 1935, he obtained a patent for the formation of new polyamides, including one from adipic acid and hexamethylenediamene. After four years of development work, which cost Du Pont some $27 million, this new polyamide, or nylon, reached the stage of commercial production, beginning on 23 October 1938. Nylon stockings appeared the following year and 64 million were sold during the first twelve months. However, Carothers saw none of this spectacular success: he had died by his own hand in 1937, after a long history of gradually intensifying depression.[br]Principal Honours and DistinctionsElected to the National Academy of Science 1936 (he was the first industrial organic chemist to be so honoured).BibliographyH.M.Whitby and G.S.Whitby, 1940, Collected Papers of Wallace H.Carothers on Polymerisation, New York.Further ReadingR.Adams, 1939, memoir, Biographical Memoirs of the National Academy of Sciences 20:293–309 (includes a complete list of Carothers's sixty-two scientific papers and most of his sixty-nine US patents).LRDBiographical history of technology > Carothers, Wallace Hume

18 De Forest, Lee
SUBJECT AREA: Broadcasting, Electronics and information technology, Photography, film and optics, Recording, Telecommunications[br]b. 26 August 1873 Council Bluffs, Iowa, USAd. 30 June 1961 Hollywood, California, USA[br]American electrical engineer and inventor principally known for his invention of the Audion, or triode, vacuum tube; also a pioneer of sound in the cinema.[br]De Forest was born into the family of a Congregational minister that moved to Alabama in 1879 when the father became President of a college for African-Americans; this was a position that led to the family's social ostracism by the white community. By the time he was 13 years old, De Forest was already a keen mechanical inventor, and in 1893, rejecting his father's plan for him to become a clergyman, he entered the Sheffield Scientific School of Yale University. Following his first degree, he went on to study the propagation of electromagnetic waves, gaining a PhD in physics in 1899 for his thesis on the "Reflection of Hertzian Waves from the Ends of Parallel Wires", probably the first US thesis in the field of radio.He then joined the Western Electric Company in Chicago where he helped develop the infant technology of wireless, working his way up from a modest post in the production area to a position in the experimental laboratory. There, working alone after normal working hours, he developed a detector of electromagnetic waves based on an electrolytic device similar to that already invented by Fleming in England. Recognizing his talents, a number of financial backers enabled him to set up his own business in 1902 under the name of De Forest Wireless Telegraphy Company; he was soon demonstrating wireless telegraphy to interested parties and entering into competition with the American Marconi Company.Despite the failure of this company because of fraud by his partners, he continued his experiments; in 1907, by adding a third electrode, a wire mesh, between the anode and cathode of the thermionic diode invented by Fleming in 1904, he was able to produce the amplifying device now known as the triode valve and achieve a sensitivity of radio-signal reception much greater than possible with the passive carborundum and electrolytic detectors hitherto available. Patented under the name Audion, this new vacuum device was soon successfully used for experimental broadcasts of music and speech in New York and Paris. The invention of the Audion has been described as the beginning of the electronic era. Although much development work was required before its full potential was realized, the Audion opened the way to progress in all areas of sound transmission, recording and reproduction. The patent was challenged by Fleming and it was not until 1943 that De Forest's claim was finally recognized.Overcoming the near failure of his new company, the De Forest Radio Telephone Company, as well as unsuccessful charges of fraudulent promotion of the Audion, he continued to exploit the potential of his invention. By 1912 he had used transformer-coupling of several Audion stages to achieve high gain at radio frequencies, making long-distance communication a practical proposition, and had applied positive feedback from the Audion output anode to its input grid to realize a stable transmitter oscillator and modulator. These successes led to prolonged patent litigation with Edwin Armstrong and others, and he eventually sold the manufacturing rights, in retrospect often for a pittance.During the early 1920s De Forest began a fruitful association with T.W.Case, who for around ten years had been working to perfect a moving-picture sound system. De Forest claimed to have had an interest in sound films as early as 1900, and Case now began to supply him with photoelectric cells and primitive sound cameras. He eventually devised a variable-density sound-on-film system utilizing a glow-discharge modulator, the Photion. By 1926 De Forest's Phonofilm had been successfully demonstrated in over fifty theatres and this system became the basis of Movietone. Though his ideas were on the right lines, the technology was insufficiently developed and it was left to others to produce a system acceptable to the film industry. However, De Forest had played a key role in transforming the nature of the film industry; within a space of five years the production of silent films had all but ceased.In the following decade De Forest applied the Audion to the development of medical diathermy. Finally, after spending most of his working life as an independent inventor and entrepreneur, he worked for a time during the Second World War at the Bell Telephone Laboratories on military applications of electronics.[br]Principal Honours and DistinctionsInstitute of Electronic and Radio Engineers Medal of Honour 1922.

19 Pierce, John Robinson
[br]b. 27 March 1910 Des Moines, Iowa, USA[br]American scientist and communications engineer said to be the "father" of communication satellites.[br]From his high-school days, Pierce showed an interest in science and in science fiction, writing under the pseudonym of J.J.Coupling. After gaining Bachelor's, Master's and PhD degrees at the California Institute of Technology (CalTech) in Pasadena in 1933, 1934 and 1936, respectively, Pierce joined the Bell Telephone Laboratories in New York City in 1936. There he worked on improvements to the travelling-wave tube, in which the passage of a beam of electrons through a helical transmission line at around 7 per cent of the speed of light was made to provide amplification at 860 MHz. He also devised a new form of electrostatically focused electron-multiplier which formed the basis of a sensitive detector of radiation. However, his main contribution to electronics at this time was the invention of the Pierce electron gun—a method of producing a high-density electron beam. In the Second World War he worked with McNally and Shepherd on the development of a low-voltage reflex klystron oscillator that was applied to military radar equipment.In 1952 he became Director of Electronic Research at the Bell Laboratories' establishment, Murray Hill, New Jersey. Within two years he had begun work on the possibility of round-the-world relay of signals by means of communication satellites, an idea anticipated in his early science-fiction writings (and by Arthur C. Clarke in 1945), and in 1955 he published a paper in which he examined various possibilities for communications satellites, including passive and active satellites in synchronous and non-synchronous orbits. In 1960 he used the National Aeronautics and Space Administration 30 m (98 1/2 ft) diameter, aluminium-coated Echo 1 balloon satellite to reflect telephone signals back to earth. The success of this led to the launching in 1962 of the first active relay satellite (Telstar), which weighed 170 lb (77 kg) and contained solar-powered rechargeable batteries, 1,000 transistors and a travelling-wave tube capable of amplifying the signal 10,000 times. With a maximum orbital height of 3,500 miles (5,600 km), this enabled a variety of signals, including full bandwidth television, to be relayed from the USA to large receiving dishes in Europe.From 1971 until his "retirement" in 1979, Pierce was Professor of Electrical Engineering at CalTech, after which he became Chief Technologist at the Jet Propulsion Laboratories, also in Pasadena, and Emeritus Professor of Engineering at Stanford University.[br]Principal Honours and DistinctionsInstitute of Electrical and Electronics Engineers Morris N.Liebmann Memorial Award 1947; Edison Medal 1963; Medal of Honour 1975.
