In 1897 Braun built the first cathode ray tube or "Braun Tube" as it is referred to 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."
