Who dated Emil Artin?

Emil Artin (German: [ˈaʁtiːn]; March 3, 1898 – December 20, 1962) was an Austrian mathematician of Armenian descent.

Artin was one of the leading mathematicians of the twentieth century. He is best known for his work on algebraic number theory, contributing largely to class field theory and a new construction of L-functions. He also contributed to the pure theories of rings, groups and fields.

Along with Emmy Noether, he is considered the founder of modern abstract algebra.

Helene (Hel) Braun (June 3, 1914 – May 15, 1986) was a German mathematician who specialized in number theory and modular forms. 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.

She is known for proving the convergence of the Eisenstein series in the space of Siegel modular forms. She also developed the foundations of the theory of Hermitian modular forms.
