Jaroslav Šafránek

Jaroslav Šafránek (May 23, 1890, in Pilsen – August 22, 1957, in Prague) was a Czechoslovak physicist who, in the second half of the 1930s, designed a system for the transmission of visual images by low-line mechanical television, which made the production of an authentic spatial impression of the picture, transmitted on the screen, possible. His discovery was, unfortunately, largely ignored by the Czechoslovakian community. Provided by Wikipedia
