Dale Husemöller (also spelled Husemoller) is an American mathematician specializing in algebraic topology and homological algebra who is known for his books on fibre bundles, elliptic curves, and, in collaboration with John Milnor, symmetric bilinear forms.
His dissertation topic was Mappings, Automorphisms and Coverings of Riemann Surfaces.
During Husemöller's career, he spent several sabbatical years as a visiting scholar at the Institut des Hautes Études Scientifiques (IHES) and at the University of Bonn.
Professor Husemöller's five children Carl, Anna, Erich, Kurt, and Greta grew up on the Haverford College campus, and spent sabbatical years and subsequent summers with him at the Résidence de l'Ormaille at the IHES in France, and for another year at the Ernst-Moritz-Arndt Gymnasium in Bonn while he was at the University there.
Professor Husemöller has 10 grandchildren, Colette, Adrian, Ingrid, Paloma, Atena, Alexei, Annika, Jacob, Rose, and Mbali.
