Bernhard Hermann Neumann AC FRS (15 October 1909 – 21 October 2002) was a German-born British-Australian mathematician who was one of the leading figures in group theory, greatly influencing the direction of the subject.
Early life and education
He earned a PhD at the University of Cambridge in 1935 and a Doctor of Science at the University of Manchester in 1954. His students included Gilbert Baumslag, László Kovács, Michael Newman, and James Wiegold. His wife, Hanna Neumann, and son, Peter M. Neumann, are also notable for their contributions to group theory.
The group-theoretic notion of HNN extension (where HNN stands for Higman–Neumann–Neumann) is named in (second) part after him.
