Ascher Wagner

Ascher Otto Wagner (12 October 1930, in Vienna – 27 May 2000, in London) was an Austrian and British mathematician, specializing in the theory of finite groups and finite projective planes. He is known for the Dembowski–Wagner theorem [de].^[1]

Ascher Wagner received his Ph.D. in 1958 with dissertation Some Problems on Projective Planes and Related Topics in the Theory of Algebraic Operations supervised by Kurt Hirsch.^[2] Wagner was a faculty member at the University of London and then at the University of Birmingham.

In 1958 he married Gillian Mary Jaidka (1929–1993) in Hampstead, London.
