Irmgard Gawehn and the topological classification of manifolds. An attempt at rehabilitation.

Teun Koetsier (VU) and Jan van Mill (VU and UVA)


Abstract: The talk is about the life and work of Irmgard Gawehn, a female German topologist.In the 1920s she wrote a brilliant Ph D thesis on the topological characterization of the 2-sphere.From 1928-1930 she was L. E. J. Brouwer's assistant at the University of Amsterdam.In the late 20th century Hans Freudenthal claimed that Gawehn had not written her thesis herself.We will discuss the significance of her topological work and we will critically examine Freudenthal's claim.
