Leonard Jimmie Savage
Leonard Jimmie Savage, called Jimmie Savage, but he published as Leonard Savage, (originally Leonard Ogashevitz, born November 20, 1917 in Detroit, † November 1, 1971 in New Haven, Connecticut) was an American statistician and mathematician.
The name change from Ogashevitz to Savage had first his father in 1920 completed, Leonard J. Savage took over this than he did research on secret government projects. Savage studied at Wayne University in Detroit and later at the University of Michigan Chemical Engineering. As he he could because of its extreme refractive error caused a fire in the chemistry lab, the study of chemistry not continue and joined the physics and finally to mathematics. In 1938, he earned his bachelor 's degree as a student of Raymond Wilder. In 1941 he received his doctorate in Sumner Myers (The Application of Vectorial Methods to the Study of Distance Spaces ). After that, he was 1941/42, the Institute for Advanced Study ( IAS). 1942/43, he was instructor at Cornell University and undertook during the Second World War followed war-related research tasks at Brown University and the statistical research group at Columbia University. In the time at the IAS, he was a close colleague of John von Neumann. 1944 began his employment with statistics. In 1945 he was a year with Richard Courant at New York University and then. Using a Rockefeller fellowship at the University of Chicago, where he worked with Milton Friedman ( whom he met already at Columbia University ) in Economics and with Paul Halmos The Friedman - Savage utility function ( utility function) is named after a paper by Friedman and Savage .. In 1949 he was in Chicago with Allen Wallis one of the founders of the Faculty of Statistics. 1951/52, he was a Guggenheim Fellow and Fulbright Scholar in Paris and Cambridge. In 1954 he became a professor in Chicago and was 1956-1959 Board of the Faculty of Statistics. In 1959 he lectured in London, which led to a seminar ( which was attended among others Egon Pearson ), which was published as a book .. In 1960 he became a professor at the University of Michigan and in 1964 at Yale University. There he worked closely with Frank Anscombe.
He dealt inter alia with the basics of statistics (also philosophical points ), Bayesian statistics and statistics in game theory as well as applications in economics. He used the Bayesian statistics for access to its basics of statistics, that is, the subjective view of probabilities as expectations as a player. He was influenced by Bruno de Finetti here.
In 1957/58 he was president of the Institute of Mathematical Statistics. In 1963 he became an honorary doctorate from the University of Rochester. In 1958 he was invited speaker at the International Congress of Mathematicians in Edinburgh ( Recent tendencies in the foundations of statistics ).
He was married twice, his first wife since 1938 to the division in 1964. From this first marriage he had two sons. His son Samuel Linton Savage, who received his doctorate in 1973 at Yale University in computer science, wrote the book The flaw of averages. His brother Richard Savage ( born 1925 ) was also a noted statistician.
