Joseph Slepian
Joseph Slepian (born February 11, 1891 in Boston , † December 19, 1969 in Swissvale , Pennsylvania ) was an American mathematician and electrical engineer. He became known for theoretical developments and inventions in electrical engineering .
Slepian studied at Harvard University with a bachelor's degree in 1911 and a doctorate in mathematics with George David Birkhoff in 1913 (On the Functions of a Complex Variable Defined by an Ordinary Differential Equation of the First Order and First Degree). As a post-doctoral student he was at the University of Göttingen and the Sorbonne . 1914/15 he was an instructor at Cornell University .
From 1915 Slepian was with Westinghouse Electric , where he was initially in the railway engines department, in 1917 he moved to the research department in Forest Hills (Pennsylvania) , which he headed from 1922 to 1926, where he was a consulting engineer from 1926 and an associate from 1938 to 1956 Research Director. He was involved in the development of over 200 patents. In 1951 he suffered a stroke.
He improved devices in high voltage technology such as the Ignitron , miniature circuit breakers and lightning protection . He invented the English autovalve lightning arrester . He examined the effect of strong thunderstorms on high-voltage cable systems, the spread of electricity in gases and arc - cathode . In 1927 he patented the betatron which is used to accelerate electrons with variable magnetic fields. During the Second World War he worked on isotope enrichment with centrifuges.
He was a member of the National Academy of Sciences (1941). In 1947 he received the IEEE Edison Medal and in 1932 the John Scott Medal. He was an honorary doctor from the Case Institute of Technology and the University of Leeds . In 1928 he became a fellow of the American Physical Society and in 1945 of the Institute of Radio Engineers .
Joseph Slepian was the father of mathematician David Slepian .
