Bernhard Hermann Neumann AC FRS (15 October 1909 – 21 October 2002) was a German-born British-Australian mathematician who was a leader in the study of group theory.
Early life and education
After gaining a D.Phil. from Friedrich-Wilhelms Universität in Berlin in 1932 he earned a Ph.D. at the University of Cambridge in 1935 and a Doctor of Science at the University of Manchester in 1954. His doctoral students included Gilbert Baumslag, László Kovács, Michael Newman, and James Wiegold. After war service with the British Army, he became a lecturer at University College, Hull, before moving in 1948 to the University of Manchester, where he spent the next 14 years. In 1954 he received a DSc from the University of Cambridge.
In 1962 he migrated to Australia to take up Foundation Chair of the Department of Mathematics within the Institute of Advanced Studies of the Australian National University (ANU), where he served as head of the department until retiring in 1974. In addition he was a senior research fellow at the CSIRO Division of Mathematics and Statistics from 1975 to 1977 and then honorary research fellow from 1978 until his death in 2002.
He was an invited speaker of the International Congress of Mathematicians in 1936 at Oslo and in 1970 at Nice. He was elected a Fellow of the Royal Society in 1959. In 1994, he was appointed a Companion of the Order of Australia (AC).
The Australian Mathematical Society awards a student prize named in his honour. The group-theoretic notion of HNN extension (where HNN stands for Higman–Neumann–Neumann) is named in (second) part after him.
