Biography

Nelli Neumann was born in Breslau, Prussia, the only child of Jewish parents Max and Sophie Neumann. Her father was a judicial officer, while her mother died when Nelli was two years old.{{r|jewishwomen}} After ten years in the private Höhere Töchterschule in Breslau, Neumann attended grammar courses and graduated from the König-Wilhelm-Gymnasium boys' school in 1905.{{r|jewishwomen}} Her father promoted her mathematical talent by arranging private mathematics lessons given by Richard Courant. The two went on to study together at the Universities of Breslau and Zürich. Neumann would return to Breslau for her doctorate, for which she completed her thesis in 1909 under the supervision of Rudolf Sturm.{{r|mgp}} After Courant received his post-doctoral degree at Göttingen University, they married in the summer of 1912.{{r|yadvashem}}
Turning down a post-doctoral position at the University of Breslau, Neumann then took courses that qualified her to become a secondary school teacher. She also worked in the career counselling centre for female students at Göttingen, which had been set up by the Frauenbildung-Frauenstudium association.{{r|yadvashem}}
Nelli's marriage became increasingly difficult, and she and Courant divorced on 16 February 1916. After the First World War she moved to Essen, where she taught mathematics, physics and chemistry at the {{ill|lt=Luisenschule|Luisenschule (Essen)|de|Luisenschule Essen}}.{{r|yadvashem}} Soon after the Nazis took power, on 27 September 1933, she lost her position under the Law for the Restoration of the Professional Civil Service.{{cite book|title=A Richer Picture of Mathematics: The Göttingen Tradition and Beyond|first=David E.|last=Rowe|author-link=David E.
