Artur Winternitz
Artur Winternitz (born June 16, 1893 in Oxford , † July 9, 1961 in Scuol , Switzerland ) was a British mathematician who studied geometry .
Winternitz, a son of the Indologist Moriz Winternitz , studied mathematics at the German University in Prague , where he received his doctorate in 1917 ( on a class of linear functional inequalities and on convex functionals ) and completed his habilitation in 1921. In 1931 he became an associate professor there. As a Jew, he and his family were threatened by the National Socialists. In 1939 he went to England, where he quickly obtained British citizenship because he was born in Oxford. Originally he wanted to go to the USA and therefore wrote to Hermann Weyl in November 1938 . He lectured at Oxford and was supported by the Leverhulme Foundation.
Winternitz dealt with differential geometry, affine and projective geometry and topology (like the Jordan curve theorem ). According to Pinl, his strengths lay in critical reconsideration of known theories and finding gaps in these theories.
He gave a new treatment of the differential geometry of the space curves (with an accompanying tripod named after him) and the axiomatic structure of projective three-dimensional geometry.
Josef Winternitz was his brother.
He had been married to Anna Steinherz (1897–1961) since 1925, whose father was a professor of Austrian history and close friends with Moriz Winternitz. They had a son John (born 1931).
