George Harold Brown

Died 11 Dec 1987 at age 79 (born 14 Oct 1908).American electrical engineer, a pioneer in radio-thermics, who made major contributions to the development of radio and television broadcast antennas. In 1936, Brown invented the so-called turnstyle antenna for television broadcasting. Because of this, the Federal Communications Commission (FCC) adopted a TV system of 441 lines. In 1938, Brown developed the vestigial sideband filter for use in television transmission, doubling the horizontal resolution of television pictures at any given bandwith. During WW II, with RCA's researchers, George Brown's group used radio-frequency heating in the bulk dehydration of penicillin at E.R. Squibb, a "sewing machine" for thermoplastics, and more consistent riveting and welding techniques.Image: Modern weather satellite receiving turnstyle antenna.
