Bio/Description
Inventor of the cathode-ray tube, Braun built the first such device in 1897 — known as the "Braun Tube" in German-speaking countries. During the development of radio, he also worked on wireless telegraphy. Around 1898, he invented a crystal diode rectifier, or Cat's whisker diode.
Guglielmo Marconi used Braun's patents, among others. Braun's British patent on tuning was used by Marconi in many of his tuning patents. Marconi would later admit to Braun himself that he had "borrowed" portions of Braun's work.
In 1909 Braun shared the Nobel Prize for physics with Marconi for "contributions to the development of wireless telegraphy."
