Raymond Redheffer

from Wikipedia, the free encyclopedia

Raymond "Ray" M. Redheffer (born April 17, 1921 in Chicago , Illinois - † May 13, 2005 ) was an American mathematician .

Redheffer went to school in North Carolina and studied from 1939 at the Massachusetts Institute of Technology (MIT), where he received his doctorate in 1948 under Norman Levinson ( Separation of Laplace's Equation ). During the war he was at the MIT Radiation Laboratory. From 1948 to 1950 he taught as a Peirce Fellow at Harvard University . In 1950 he came to the University of California, Los Angeles , where he was given a full professorship in 1960 and stayed for the rest of his career until his retirement in 1991. He was known for his excellent teaching, which won the University's Distinguished Teacher Award in 1969 . He was visiting professor in Germany several times for a long time (he spoke fluent German), for example in Hamburg and Karlsruhe .

He dealt with analysis (partial and ordinary differential equations, differential inequalities, function theory) and applications, for example in electrical engineering. He has published over 200 scientific articles.

Redheffer has lectured on mathematics to a wide variety of audiences from deaf students to glassblowers, and has produced educational films with designers Charles and Ray Eames . With Charles Eames (on behalf of IBM ) he developed a chronological table of the history of mathematics ( Men of Mathematics ), which hung in numerous university rooms, as well as portraits of important mathematicians in the IBM series Mathematica .

In 1976 and 1985 he was Senior Fellow of the Alexander von Humboldt Foundation and in 1957 and 1961 Fulbright Research Scholar. In 1977 he became a member of the Leopoldina . In 1991 he received an honorary doctorate from the University of Karlsruhe .

He was a passionate mountaineer and piano player.
