Felix Adalbert Behrend (23 April 1911 – 27 May 1962) was a German mathematician of Jewish descent who escaped Nazi Germany and settled in Australia. His research interests included combinatorics, number theory, and topology. Behrend's theorem and Behrend sequences are named after him.
Behrend was born on 23 April 1911 in Charlottenburg, a suburb of Berlin. He was one of four children of Dr. Felix W. Behrend, a politically liberal mathematics and physics teacher. Although of Jewish descent, their family was Lutheran. Behrend followed his father in studying both mathematics and physics, both at Humboldt University of Berlin and the University of Hamburg, and completed a doctorate in 1933 at Humboldt University.[1][2][3][4] His dissertation, Über numeri abundantes [On abundant numbers] was supervised by Erhard Schmidt.[1][5]
With Adolf Hitler's rise to power in 1933, Behrend's father lost his job, and Behrend himself moved to Cambridge University in England to work with Harold Davenport and G. H. Hardy. After taking work with a life insurance company in Zürich in 1935 he was transferred to Prague, where he earned a habilitation at Charles University in 1938 while continuing to work as an actuary. He left Czechoslovakia in 1939, just before the war reached that country, and returned through Switzerland to England, but was deported on the HMT Dunera to Australia as an enemy alien in 1940.[1][2][3][4]
Although both Hardy and J. H. C. Whitehead intervened for an early release, he remained in the prison camps in Australia, teaching mathematics there to the other internees. After Thomas MacFarland Cherry added to the calls for his release, he gained his freedom in 1942 and began working at the University of Melbourne. He remained there for the rest of the career, and married a Hungarian dance teacher in 1945 in the Queen's College chapel; they had two children.[1][2][3] Although his highest rank was associate professor, Bernhard Neumann writes that "he would have been made a (personal) professor" if not for his untimely death.[2] He died of brain cancer on 27 May 1962 in Richmond, Victoria, a suburb of Melbourne.[1][2][3]
