Zworykin Develops an Early Type of Television (Great Events from History II: Science and Technology Series)
Article abstract: Zworykin’s concept of an all-electronic television receiver foreshadowed the development of modern television systems.
Summary of Event
Although Vladimir Zworykin is popularly known as the father of television, his work in the 1920’s actually built upon the contributions of numerous scientists and electrical engineers who began theorizing about possible applications of electricity as early as the 1830’s. Antecedents of all-electronic television can be found in several different, but related, areas in electrical engineering. The invention of the telegraph in the 1830’s demonstrated the possibility of modulating an electrical current to transmit coded signals; the invention of the telephone in 1876 showed that sound waves could be converted into electrical impulses and back again. Heinrich Hertz’s measurements of electromagnetic waves in the late 1880’s provided empirical evidence of earlier theoretical speculations about the nature of electricity. Guglielmo Marconi’s work with radio is reported by Orrin Dunlap as having been a direct response to Marconi’s reading of Hertz’s paper. In any event, engineers and scientists who had been working on the electrical transmission of images by wire responded to the challenge of achieving the wireless projection of visual images almost simultaneously with the development of radio.
