US Patent No. Born July 30, - Died July 29, Like many European intellectuals of the 20th century, Zworykin was driven to the United States by the recurrent religious persecution and political repression which rocked Europe and Russia. He came to America in , 3 years after the Russian Revolution, and joined the research staff of Westinghouse Electric and Manufacturing Company in Pittsburgh.
In he went to the Radio Corporation of America RCA , where he was made director of the electronics research laboratory.
Zworykin was one of the earliest pioneers in the development of television. Before he left the St. Petersburg laboratory of Boris Rosing in , he had the germ of an idea for an improved television system. When he joined Westinghouse in , he hoped to be able to continue his work but soon discovered that firm was interested only in radio research. He left Pittsburgh to join a small development company in Kansas but returned to Westinghouse in , this time with the agreement that he could continue work on television.
According to an interview conducted for the RCA Engineers Collection, July 4, , Zworykin details early developments with primitive geometric pictures generated as early as In that year he applied for a patent on his "Iconoscope," a device which transmitted television images quickly and sharply.

In , another German, Karl Braun, invented the cathode ray oscilloscope, in which magnetic fields directed the rays onto a fluorescent material at the end of a tube. Rosing went into exile and died. In , Zworykin's wife Tatania Vasilieff, from whom he had been separated for better than a decade, divorced him, and he married long-time friend Katherine Polevitsky.
He was forced to retire at 65 from RCA in but continued supporting and developing research, serving as director of the Medical Electronics Center at the Rockefeller Institute in New York.
