Karl Ferdinand Braun ([6 June 1850 in Fulda, Germany – 20 April 1918 in New York City, United States) was a Germany inventor, physicist and Nobel Prize in Physics laureate.
Biography Braun was educated at the University of Marburg and received a Ph.D from the University of Berlin in 1872. In 1874 he discovered that a point-contact semiconductor rectifier alternating current. He became director of the Physical Institute and professor of physics at the University of Strasbourg in 1895.
In 1897 he built the first Cathode ray tube oscilloscope. CRT technology is to this day used by most television sets and computer monitors. The cathode ray tube is still called the "Braun tube" (Braunsche Röhre) in German language-speaking countries (and in Japan: Buraun-kan).
During the History of radio, he also worked on wireless telegraphy. Around 1898, he invented a Diode 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."
Braun went to the United States at the beginning of World War I to help defend the German wireless station at Sayville, N.Y. (on Long Island) against attacks by the British controlled Marconi Corporation. (At this time the U.S. had not yet entered the war). Braun died in his house in Brooklyn (New York City) before the war ended in 1918.
