Schottky; Walter Hans Schottky (23 July 1886, Zürich, Switzerland - 4 March 1976, Pretzfeld, Germany) was a German physicist who played a major early role in developing the theory of electron and ion emission phenomena, invented the screen-grid vacuum tube in 1915 while working at Siemens, co-invented the ribbon microphone and ribbon loudspeaker along with Dr. Erwin Gerlach in 1924, and later made many significant contributions in the areas of semiconductor devices, technical physics, and technology; Schottky's father was mathematician Friedrich Hermann Schottky (1851-1935); he completed his B.S. degree in physics at the University of Berlin in 1908 and his Ph. D. in physics at the Humboldt University of Berlin in 1912, studying under Max Planck and Heinrich Rubens; he was a professor of theoretical physics at the University of Rostock from 1923 to 1927; he worked at the Siemens Research laboratories from 1914 to 1919 and again from 1927 to 1958)
