Braun, Ferdinand

Karl Ferdinand Braun was born on June 6, 1850. He was a German electrical engineer, physicist, and inventor. Braun contributed significantly to the development of radio with his 2 circuit system, which made long range radio transmissions and modern telecommunications possible, and with his invention of the phased array antenna in 1905, which led to the development of radar, smart antennas, and MIMO. Before that, he built the first cathode-ray tube in 1897, which led to the development of television, and the first semiconductor device in 1874, which led to the development of electronics, electronics engineering and the Information Age.

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, and has been called the "father of television" (shared with inventors like Paul Gottlieb Nipkow), the "great grandfather of every semiconductor ever manufactured", and a co-father of radio telegraphy, together with Marconi, laying the foundation for all modern wireless systems.
