Karl Braun

Karl Braun was a German physicist known for inventing the Braun tube, an early display device that used cathode-ray technology. This invention laid the groundwork for the development of oscilloscopes and television screens. Braun’s work was fundamental in understanding electron beams and their behavior in vacuum tubes, which advanced electronics and communication technology. His contributions helped transform how we visualize and transmit electronic signals, making complex information more accessible through visual displays.
