1869-1933

Russian engineer who invented the first cathode ray tube to reproduce television images. In 1907 Rosing was able to transmit black and white silhouettes of simple shapes using a mechanical mirror-drum as a camera and a cathode ray tube as a receiver. He was the first to suggest that electrical signals from a mechanical transmitter might be transformed into visual images when sent to a cathode ray receiver.
