Biography
Karl Ferdinand Braun was a German physicist, electrical engineer, 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 co-started the development of electronics and electronics engineering.
