Israel Halperin
Israel Halperin (born January 5, 1911 in Westmount , Québec , † March 8, 2007 ) was a Canadian mathematician who dealt with functional analysis and operator algebras. He was also known as a human rights activist.
Halperin was the son of Russian immigrants and studied at the University of Toronto with a degree in 1932 and at Princeton University , where he received his doctorate in 1936 under Salomon Bochner and John von Neumann ( Adjoints and Closures of Linear Differential Operators ). From 1939 he was at Queen's University (Kingston) , interrupted from service in the Canadian Army in World War II in an artillery research department in Ottawa (Canadian Armament Research and Development Establishment, CARDE). Most recently he was a major. After returning to his university, he was arrested for espionage for the Soviet Union in 1946 as part of the investigation after the Russian deciphering officer Igor Gouzenko defected and testified to the authorities, as well as other people such as Gordon Lunan , who incriminated Halperin. Halperin was heard before a commission which in 1947 concluded (influenced by Halperin's uncooperative behavior) that he had violated the Official Secrets Act. He returned to his university thanks to the support of University President Charles Durning (who was supported by submissions from numerous scholars such as Albert Einstein ), where he taught as a professorship until 1966 and then went to the University of Toronto, where he retired in 1976.
He was a Fellow of the Royal Society of Canada (1953), whose Henry Marshall Tory Medal he received in 1967, and an honorary doctorate from Queen's University (1989). He was also a member of the Order of Canada because of his advocacy for human rights. For this he also received the Pagels Award from the New York Academy of Sciences .
He edited various unfinished manuscripts from the estate of John von Neumann (such as his Continuous Geometries ).
Halperin had been married since 1940 and had four children, all of whom became professors: Northwestern University physics professor William Halperin , Connie Eaves (stem cell research), mathematician Stephen Halperin, and Mary Hannah.
George A. Elliott is one of his PhD students .
