Karl Ferdinand Braun was a German applied physicist who shared the 1909 Nobel Prize in Physics with Guglielmo Marconi for their contributions to the development of radio. With his two circuit system, long range radio transmissions and modern telecommunications were made possible. His invention of the phased array antenna in 1905 led to the development of radar, smart antennas, and MIMO. Braun built the first cathode-ray tube in 1897, which led to the development of television, and the first semiconductor diode in 1874, which co-started the development of electronics and electronic engineering.
