Professor Hermann Arthur Jahn (b. 31 May 1907, Colchester, England; d. 24 October 1979 Southampton) was an English scientist of German origin.^[1] With Edward Teller, he was responsible for identifying the Jahn-Teller effect.^[2]

[edit] Early life

He was the son of Friedrich Wilhelm Hermann Jahn and Marion May Curtiss. He attended Lincoln School in Lincoln.

Jahn received a BSc in Chemistry at University College, London in 1928. He received his PhD on 14 February 1935 under the supervision of Werner Heisenberg at the University of Leipzig. The title of his dissertation was "The rotation and oscillation of the methane molecule".^[3] From 1935-41 he did research at the Davy Faraday Research Laboratory at the Royal Institution in London.

From 1941-6 he was based at the Royal Aircraft Establishment at Farnborough Airfield. He was (the first) Professor of Applied Mathematics at the University of Southampton from 1949-73. He published scientific papers on quantum mechanics and group theory.

He married Karoline Schuler in 1943 in Hendon. They had a son (born 1944) and a daughter (born 1946). He died in 1979 aged 72.
