He is sometimes called the Father of Television!
Vladimir Zworykin was born in Russia in 1889. He studied science and engineering and worked on early television at St. Petersburg Institute of Technology. He came to the U.S. in 1918, during the Russian Civil War, by joining a scientific expedition in Siberia and continuing on to Alaska. Once in the U.S., Zworykin worked at the Westinghouse laboratories in Pittsburgh, Pennsylvania. He continued to work on improvements for television and earned his PhD from the University of Pittsburgh (the university that features that wonderful Cathedral of Learning I mentioned in yesterday's post!).
Zworykin helped develop cathode ray tubes, infrared image tubes, and the electron microscope.

Have you tried out the Virtual Electron Microscope?
