Elisabeth Hagemann (born 6 Mar 1906 in Essen,[2] died 1989)[3] was among the first female German mathematicians to obtain a Doctor of Philosophy degree.

Life

Her parents were Otto Hagemann, a department director at Friedrich Krupp AG, and Else Hagemann, née Clausius. Elisabeth Hagemann got her abitur from the Victoria school Essen (de) on 6 March 1926. She enlisted at Munich University in spring 1926, then at Bonn University in spring 1928, where she got her Staatsexamen in mathematics, physics, and geography on 4 March 1932.[2]

Then she worked as a school teacher in Bad Godesberg, Bonn, and Rhine Province. In May 1935, she became a research fellow (Wissenschaftlicher Assistent) of Otto Toeplitz at Bonn University. On 28 Apr 1937, she obtained her Ph.D.[2][4][5] At that time, her main advisor, Otto Toeplitz, had already been dismissed due to the Nazi Civil Service Law.[6]
