Karl Ferdinand Braun (German: [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 when he invented the phased array antenna in 1905,[1][2] which led to the development of radar, smart antennas and MIMO. He built the first cathode-ray tube, which led to the development of television. He also built the first semiconductor.

Braun shared the 1909 Nobel Prize in Physics with Guglielmo Marconi "for their contributions to the development of wireless telegraphy". He was a founder of Telefunken, one of the pioneering communications and television companies,[3] and has been called the "father of television" (shared with inventors like Paul Gottlieb Nipkow), the "great grandfather of every semiconductor ever manufactured"[4] and a co-father of radio telegraphy, together with Marconi.[5][6][7][8]
