# Dale Husemoller

**Dale Husemoller** (also spelled Husemöller) is an American mathematician specializing in algebraic topology and homological algebra who is known for his work on fibre bundles, elliptic curves, and, in collaboration with John Milnor, the book, Symmetric Bilinear Forms.

## Life and Career

Husemoller was born in 1933 in Austin, Minnesota, USA. He earned his BA in mathematics at the University of Minnesota (December 1952). He began his graduate career there as a physicist and transferring to Harvard University. There, he switched from physics to the PhD program in mathematics in November 1953.

He completed his Ph.D. at Harvard University in 1959. His doctoral supervisor was Lars Ahlfors. His dissertation topic was *Mappings, Automorphisms and Coverings of Riemann Surfaces*.[1]

After the PhD his interests shifted to topology as a faculty member at Pennsylvania State University from 1960 to 1962 and at Haverford College[2] from 1963 until his retirement in 1996. He is currently professor emeritus at Haverford. He spent several sabbatical years as a visiting scholar at the IHES and at the University of Bonn. After retirement, he was visiting lecturer at both of these places as well as at the Universities of Munich, Heidelberg, and Münster, the Tata Institute in Bombay, the Institute of Physics and Mathematics in Tehran, and the Max Planck Institute in Bonn.
