Oswald Teichmuller

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.
