Jaroslav Šafránek

Jaroslav Šafránek (23 May 1890 in Plzeň – 22 August 1957 in Prague) was a Czech physicist. n the second half of the 1930s, he 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 Czechoslovak community. Provided by Wikipedia
