Oswald Teichmuller (
1913-
1943) introduced quasi-conformal mappings and
differential geometric methods into
complex analysis. His work was published in
Deutsche Mathematik, a journal in
synthetic mathematics[?] founded by
Bieberbach[?] and has been neglected for a while for political reasons. "Rediscovered" few years after his death, theory of
Teichmuller spaces[?] was further developed by
Lars Ahlfors,
Lipman Bers[?] and others.
Teichmuller was a passionate Nazi, who joined the German army in 1939 and died fighting on a Russian front[?].
