The evolution of electrical and electronics engineering and the Proceedings of the IRE: 1913-1937

Article Abstract:

The period of 1913 to 1937, as chronicled and influenced by the Proceedings of the IRE (Institute of Radio Engineers) journal, is documented. The preeminent technology at the time was radio communications and early long wave systems. The impact of the US Navy and World War I, the development of the Poulsen arc transmitter, the audion, the regenerative oscillator, the magnetic amplifier, the dynatron, the Alexanderson radio alternator, and other work at RCA, GE, and AT&T are described. Early radio broadcasting, short wave radio, microwave communications, television, and FM broadcasting are also briefly reviewed. The Proceedings offered 1586 technical papers on these subjects in the first 25 years and was found to be the leading source of relevant technical information.

Scanning the past: Browder J. Thompson

Article Abstract:

Browder J. Thompson first suggested that electron multiplication could be applied to a grid-controlled vacuum-tube amplifier in a paper published in Proceedings of the IRE (Institute of Radio Engineers) in 1941. The paper showed that the tube would be suitable in ultrahigh-frequency applications where input capacitance was a problem. According to Thompson, electron multiplication could substantially reduce input capacitance. The commercial version of these tubes became known as 'acorn tubes,' and Thompson was recognized for his contribution in the field in 1936 when he received the Morris Liebmann Prize from IRE. Thompson was killed in a plane crash in 1944. The Browder J. Thompson Memorial Prize Award was established to recognize outstanding authors of IRE papers.

The Faraday Bicentennial

Article Abstract:

September 1991 marks the 200th anniversary of the birth of Michael Faraday, the British natural philosopher. Faraday made several contributions to electrical science. In 1831, Faraday showed that relative motion between a magnet and a conductor placed nearby produced an electromotive force in the conductor, which led to the development of magneto-electric generators and the dynamo. In the 1840's, Faraday discussed a theory of the electromagnetic field and discovered that a magnet could make the plane of polarization of a beam of light rotate. Faraday died in 1867.
