Boris Lvovich Rosing (Russian: Бори́с Льво́вич Ро́зинг) (1869 – 1933) was a Russian scientist and inventor in the field of television. In 1907, he envisioned a TV system using the CRT that was practically demonstrated in 1911. By 1907, Rosing had developed a television system which employed a mechanical disc system as a camera, and a very early cathode ray tube (developed in Germany by Karl Ferdinand Braun) as a receiver. The system was primitive, but it was more electronic than mechanical. Rosing and Vladimir Zworykin exhibited a television system in 1910, using a mechanical scanner in the transmitter and the electronic Braun tube in the receiver. 1869 is a common year starting on Friday (link will take you to calendar). ... 1933 was a common year starting on Sunday (link will take you to calendar). ...
