"Zworykin was born in Murom, 200 miles east of Moscow, and studied electrical engineering at the Imperial Institute of Technology. Boris Rosing, a professor in charge of laboratory projects, tutored Zworykin and introduced his student to his experiments of transmitting pictures by wire. Together they experimented with a very early cathode-ray tube, developed in Germany by Karl Ferdinand Braun. Rosing and Zworykin exhibited a television system in 1910, using a mechanical scanner in the transmitter and the electronic Braun tube in the receiver. Rosing disappeared during the Bolshevik Revolution of 1917. Zworykin escaped and briefly studied X-rays under Paul Langevin in Paris, before moving to the United States in 1919, to work at the Westinghouse laboratory in Pittsburgh. On November 18, 1929, at a convention of radio engineers, Zworykin demonstrated a television receiver containing his kinescope."
