Braun Invents the Cathode Ray Tube

Karl Ferdinand Braun, a German physicist, invents the first cathode-ray tube, the basis of all modern television cameras and receivers. Braun has the idea of placing two electromagnets around the neck of the tube to make the electron beam move horizontally and vertically. On the fluorescent screen the movement of the electron beam has the effect of tracing visible lines on the screen.
