Theodore Holstein
Theodore Holstein (18 September 1915– 8. May 1985) was an American theoretical physicist, specialized in solid-state physics and atomic physics. With Henry Primakoff in 1940 he introduced the Holstein-Primakoff transformation, of importantance for the theory of spin waves. Other significant papers included the polaron (introduction of the small polaron), infrared absorption of metals, a microscopic theory of the collision drag phenomenon by Brian Pippard, Bloch electrons in magnetic fields (Hall effect) and his review on the transport properties in an electron-phonon gas. He corrected the Förster-Dexter theory of photoinduced energy transfer between molecules and found new mechanisms for energy transfer in disordered systems. He is also known for introducing the Holstein–Herring method. Life Theodore David Holstein was born in 1915 in New York City, United States. Holstein studied at New York University, earning a bachelor's degree in 1935 and his Master's degree was earned at Columbia University in 1936. For his PhD studies he returned to New York University. His thesis Passage of Neutrons through Ferromagnetic Materials was supervised by , and he earned his degree in 1940. From 1941 he worked in a research lab at Westinghouse Electric Corporation. In 1960, he left Westinghouse and became a professor at
