Biography

In 1931, Magnus received his PhD from the University of Frankfurt, in Germany. His thesis, written under the direction of Max Dehn, was entitled Über unendlich diskontinuierliche Gruppen von einer definierenden Relation (der Freiheitssatz).[1]

In 1932, while working on the word problem for groups, Magnus showed that groups with one relation always have a decidable word problem.[2]

Magnus was a faculty member in Frankfurt from 1933 until 1938. He refused to join the Nazi Party and, as a consequence, was not allowed to hold an academic post during World War II. In 1947 he became a professor at the University of Göttingen.

In 1948 he emigrated to the

Polytechnic Institute of New York, before retiring in 1978. Among his doctoral students are Joan Birman, Martin Greendlinger, Edna Grossman, Herbert Keller, and Seymour Lipschutz
