Bernhard Hermann Neumann (15 October 1909 – 21 October 2002) was a German-born British-Australian mathematician, who was a leader in the study of
group theory In abstract algebra, group theory studies the algebraic structures known as groups. The concept of a group is central to abstract algebra: other well-known algebraic structures, such as rings, fields, and vector spaces, can all be seen as ...

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 Doctor of Science ( la, links=no, Scientiae Doctor), usually abbreviated Sc.D., D.Sc., S.D., or D.S., is an academic research degree awarded in a number of countries throughout the world. In some countries, "Doctor of Science" is the degree used f ...
at the University of Manchester in 1954. His doctoral students included Gilbert Baumslag, László Kovács, Michael Newman, and
James Wiegold James "Jim" Wiegold (15 April 1934 – 4 August 2009) was a Welsh mathematician. Born in Trecenydd, Caerphilly, he earned a Ph.D. at the University of Manchester, England in 1958, studying under Bernhard Neumann, and is most notable for h ...
. 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 the Foundation Chair of the Department of Mathematics within the Institute of Advanced Studies of the

(ANU), where he served as head of the department until retiring in 1975. 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. His wife,
Hanna Neumann Johanna (Hanna) Neumann (née von Caemmerer; 12 February 1914 – 14 November 1971) was a German-born mathematician who worked on group theory. Biography Neumann was born on 12 February 1914 in Lankwitz, Steglitz-Zehlendorf (today a distr ...
, and sons, Peter M. Neumann and Walter Neumann, are also notable for their contributions to group theory. 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 (Higman-Neumann-Neumann) extension bears the names of Bernard and his wife Hanna, from their joint paper with Graham Higman (who later supervised the PhD of their son Peter).
