Zworykin, Vladimir (Kosma)

(born July 30, 1889, Murom, Russia—died July 29, 1982, Princeton, N.J., U.S.) Russian-born U.S. electronic engineer and inventor. He immigrated to the U.S. in 1919. While with Westinghouse Electric Corp. (1920–29), he filed patent applications for his inventions of the iconoscope (a TV transmission tube, 1923) and the kinescope (TV receiver, 1924), which formed the first all-electronic TV system. He patented a colour TV system in 1928. In 1929 he became director of electronic research at RCA. His electron image tube, sensitive to infrared light, was the basis for devices first used in World War II for seeing in the dark.

Zworykin, Vladimir (Kosma) (1889–1982) physicist, inventor; born in Murom, Russia. Trained in physics in Russia and France, he emigrated to the U.S.A. in 1919 and worked for the Westinghouse Corp. until 1929. In that year he demonstrated a television receiver with a cathode ray tube of his invention that contained the main features of modern picture tubes.
