Vladimir
Zworykin was
born in Murom, Russia in 1889. He studied
at the St Petersburg Institute of Technology and during the First
World War served as a radio officer.
Zworykin emigrated to the United States in 1919. He joined the Westinghouse
Corporation in Pittsburgh, Pennsylvania, and in 1923 took out a patent
for the iconoscope that could be used as a TV camera tube. The following
year he added the kinescope (a TV receiver tube). After becoming director
of electronic research for the Radio Corporation of America (RCA)
he continued to work on producing an effective television set.
Working with James Hiller, Zworykin developed an electron microscope
in 1939. During the Second World War he produced
an electronic image tube that was sensitive to infrared light. This
was used for several inventions that enabled soldiers in the war to
see in the dark.
In 1957 Zworykin patented a device that used ultraviolet light and
television to throw a colour picture of living cells on a screen.
This paved the way for new biological investigations to take place.
Vladimir Zworykin died in 1982.
