Vladimir Kosma Zworykin (1889-1982) a Russian-American physicist and inventor who, in 1928, patented the idea of using magnetic fields to guide cathode rays in order to produce images on a fluorescent screen. This mechanism is the basis for all conventional television sets and computer monitors. He became director of research at Radio Corporation of America (RCA), where he also developed the first practical television camera, which he named the iconoscope. In 1939, Zworykin invented the first electron microscope.
