Walter H. Schottky
Walter Schottky was a German physicist and electrical engineer who played a major early role in developing the theory of thermionic emission, invented the screen-grid vacuum tube in 1915, co-invented the ribbon microphone and ribbon loudspeaker along with Erwin Gerlach in 1924, and later made many significant contributions in the areas of semiconductor devices, technical physics, and technology.
