Vladimir Kosma ZworykinBorn 30 Jul 1889; died 29 Jul 1982 at age 92.Russian-American physicist and electronics engineer who is known as “the Father of Television.” Concurrent with the start of radio broadcasting, Zworykin was developing a system of transmitting sound and pictures. Other inventors were using a motorized, mechanical scanning system with rotating disks capable of a picture about one inch square. It was heavy, bulky and impractical for home use. Zworykin, at Westinghouse, instead developed an electronic scanning television system using his innovations, the iconoscope and kinescope, the forerunners of today's television camera. He also invented the electron microscope. |
