3 Forrester, Jay Wright
SUBJECT AREA: Electronics and information technology[br]b. 14 July 1918 Anselmo, Nebraska, USA[br]American electrical engineer and management expert who invented the magnetic-core random access memory used in most early digital computers.[br]Born on a cattle ranch, Forrester obtained a BSc in electrical engineering at the University of Nebraska in 1939 and his MSc at the Massachusetts Institute of Technology (MIT) in Cambridge, Massachusetts, where he remained to teach and carry out research. Becoming interested in computing, he established the Digital Computer Laboratory at MIT in 1945 and became involved in the construction of Whirlwind I, an early general-purpose computer completed in March 1951 and used for flight-simulation by the US Army Air Force. Finding the linear memories then available for storing data a major limiting factor in the speed at which computers were able to operate, he developed a three-dimensional store based on the binary switching of the state of small magnetic cores that could be addressed and switched by a matrix of wires carrying pulses of current. The machine used parallel synchronous fixed-point computing, with fifteen binary digits and a plus sign, i.e. 16 bits in all, and contained 5,000 vacuum tubes, eleven semiconductors and a 2 MHz clock for the arithmetic logic unit. It occupied a two-storey building and consumed 150kW of electricity. From his experience with the development and use of computers, he came to realize their great potential for the simulation and modelling of real situations and hence for the solution of a variety of management problems, using data communications and the technique now known as interactive graphics. His later career was therefore in this field, first at the MIT Lincoln Laboratory in Lexington, Massachusetts (1951) and subsequently (from 1956) as Professor at the Sloan School of Management at the Massachusetts Institute of Technology.[br]Principal Honours and DistinctionsNational Academy of Engineering 1967.

6 Bode, Hendrik Wade
[br]b. 24 December 1905 Madison, Wisconsin, USAd. 21 June 1982 Cambridge, Massachusetts, USA[br]American engineer who developed an extensive theoretical understanding of the behaviour of electronic circuits.[br]Bode received his bachelor's and master's degrees from Ohio State University in 1924 and 1926, respectively, and his PhD from Columbia University, New York, in 1935. In 1926 he joined the Bell Telephone Laboratories, where he made many theoretical contributions to the understanding of the behaviour of electronic circuits and, in particular, in conjunction with Harry Nyquist, of the conditions under which amplifier circuits become unstable.During the Second World War he worked on the design of gun control systems and afterwards was a member of a team that worked with Douglas Aircraft to develop the Nike anti-aircraft missile. A member of the Bell Laboratories Mathematical Research Group from 1929, he became its Director in 1952, and then Director of Physical Sciences. Finally he became Vice-President of the Laboratories, with responsibility for systems engineering, and a director of Bellcomm, a Bell company involved in the Moon-landing programme. When he retired from Bell in 1967, he became Professor of Systems Engineering at Harvard University.[br]Principal Honours and DistinctionsPresidential Certificate of Merit 1946.

7 Black, Harold Stephen
[br]b. 14 April 1898 Leominster, Massachusetts, USAd. 11 December 1983 Summitt, New Jersey, USA[br]American electrical engineer who discovered that the application of negative feedback to amplifiers improved their stability and reduced distortion.[br]Black graduated from Worcester Polytechnic Institute, Massachusetts, in 1921 and joined the Western Electric Company laboratories (later the Bell Telephone Laboratories) in New York City. There he worked on a variety of electronic-communication problems. His major contribution was the discovery in 1927 that the application of negative feedback to an amplifier, whereby a fraction of the output signal is fed back to the input in the opposite phase, not only increases the stability of the amplifier but also has the effect of reducing the magnitude of any distortion introduced by it. This discovery has found wide application in the design of audio hi-fi amplifiers and various control systems, and has also given valuable insight into the way in which many animal control functions operate.During the Second World War he developed a form of pulse code modulation (PCM) to provide a practicable, secure telephony system for the US Army Signal Corps. From 1963–6, after his retirement from the Bell Labs, he was Principal Research Scientist with General Precision Inc., Little Falls, New Jersey, following which he became an independent consultant in communications. At the time of his death he held over 300 patents.[br]Principal Honours and DistinctionsInstitute of Electronic and Radio Engineers Lamme Medal 1957.Bibliography1934, "Stabilised feedback amplifiers", Electrical Engineering 53:114 (describes the principles of negative feedback).21 December 1937, US patent no. 2,106,671 (for his negative feedback discovery.1947, with J.O.Edson, "Pulse code modulation", Transactions of the American Institute of Electrical Engineers 66:895.1946, "A multichannel microwave radio relay system", Transactions of the American Institute of Electrical Engineers 65:798.1953, Modulation Theory, New York: D.van Nostrand.1988, Laboratory Management: Principles \& Practice, New York: Van Nostrand Rheinhold.Further ReadingFor early biographical details see "Harold S.

8 Kennelly, Arthur Edwin
[br]b. 17 December 1871 Colaba, Bombay, Indiad. 18 June 1939 Boston, Massachusetts, USA[br]Anglo-American electrical engineer who predicted the ionosphere and developed mathematical analysis for electronic circuits.[br]As a young man, Kennelly worked as office boy for a London engineering society, as an electrician and on a cable-laying ship. In 1887 he went to work for Thomas Edison at West Orange, New Jersey, USA, becoming his chief assistant. In 1894, with Edwin J.Houston, he formed the Philadelphia company of Houston and Kennelly, but eight years later he took up the Chair of Electrical Engineering at Harvard, a post he held until his retirement in 1930. In 1902 he noticed that the radio signals received by Marconi in Nova Scotia from the transmitter in England were stronger than predicted and postulated a reflecting ionized layer in the upper atmosphere. Almost simultaneously the same prediction was made in England by Heaviside, so the layer became known as the Kennelly-Heaviside layer. Throughout most of his working life Kennelly was concerned with the application of mathematical techniques, particularly the use of complex theory, to the analysis of electrical circuits. With others he also contributed to an understanding of the high-frequency skin-effect in conductors.[br]Principal Honours and DistinctionsPresident, American Institute of Electrical Engineers 1898–1900.

9 Gray, Elisha
SUBJECT AREA: Telecommunications[br]b. 2 August 1835 Barnesville, Ohio, USAd. 21 January 1901 Newtonville, Massachusetts, USA[br]American inventor who was only just beaten by Alexander Graham Bell in the race for the first telephone patent.[br]Initially apprenticed to a carpenter, Gray soon showed an interest in chemistry, but he eventually studied electrical engineering at Oberlin College, Oberlin, Ohio, in the late 1850s. In 1869 he founded the Western Electric Manufacturing Company, where he devised an electric-needle annunciator for use in hotels and lifts and carried out experimental work aimed at the development of a means of distant-speech communication. After successful realization of a liquid-based microphone and public demonstrations of a receiver using a metal diaphragm, on 14 February 1876 he deposited a caveat of intention to file a patent claim within three months for the invention of the telephone, only to learn that Alexander Graham Bell had filed a full patent claim only three hours earlier on the same day. Following litigation, the patent was eventually awarded to Bell. In 1880 Gray was appointed Professor of Dynamic Electricity at Oberlin College, but he appears to have retained his business interests since in 1891 he was both a member of the firm of Gray and Barton and electrician to his old firm, Western Electric. Subsequently, in 1895, he invented the TelAutograph, a form of remote-writing telegraph, or facsimile, capable of operating over short distances. The system used a transmitter in which the x and y movements of a writing stylus were coupled to a pair of variable resistors. In turn, these were connected by two telegraph wires to a pair of receiving coils, which were used to control the position of a pen on a sheet of paper, thus replicating the movement of the original stylus.[br]Bibliography1878, Experimental Research in Electro-Harmonic Telegraph and Telephony, 1867–76.Further ReadingJ.Munro, 1891, Heroes of the Telegraph.D.A.Hounshill, 1975, "Elisha Gray and the telephone.
