Karl Ferdinand Braun (German pronunciation: [ˈfɛʁdinant ˈbʁaʊn] ; 6 June 1850 – 20 April 1918) was a German electrical engineer, inventor, physicist and Nobel laureate in physics. Braun contributed significantly to the development of radio and television technology and built the first semiconductor. He shared the 1909 Nobel Prize in Physics with Guglielmo Marconi "for their contributions to the development of wireless telegraphy", was a founder of Telefunken, one of the pioneering communications and television companies,[1] and has been both called the "father of television" (shared with inventors like Paul Gottlieb Nipkow), "great grandfather of every semiconductor ever manufactured"[2] and the co-father of the radio telegraphy, together with Marconi.[3][4][5][6]
