Hel Braun

[1][2] Her autobiography, The Beginning of A Scientific Career, described her experience as a female scientist working in a male-dominated field at the time, in the Third Reich.

In 1937 she worked with Carl Ludwig Siegel in Frankfurt to study the decomposition of quadratic forms into sums of squares.

[6] In 1951, Braun moved and became a professor at the University of Hamburg where she supervised many doctoral students including Eberhard Becker, Manfred Knebusch and Karl Mathiak and while there worked with Emil Artin and other internationally acclaimed mathematicians.

[7] Braun never married, but in the 1960s while she was a professor at the University of Hamburg, she shared an apartment with Emil Artin, and their relationship was equivalent to marriage according to everyone who knew them.

A list of the publications by Hel Braun was published by Helmut Strade in the Communications of the Mathematical Society in Hamburg, Volume XI, Issue 4, 1987.
