Robert Breusch

Who was Robert Breusch?

Robert Hermann Breusch was a German-American number theorist, the William J. Walker Professor of Mathematics at Amherst College.

Breusch was born in Freiburg, Germany, and studied mathematics both at the University of Freiburg and the University of Berlin. Unable to secure a university position after receiving his doctorate, Breusch became a schoolteacher near Freiburg, where he met his future wife, Kate Dreyfuss; Breusch was Protestant, but Dreyfuss was Jewish, and the two of them left Nazi Germany for Chile in the mid-1930s. They married there, and Breusch found a faculty position at Federico Santa María Technical University in Valparaiso. In 1939, they left Chile for the United States, inviting Robert Frucht to take Breusch's place at Santa María; after some years working again as a schoolteacher, Breusch found a position at Amherst College in 1943. He became the Walker professor in 1970, and retired to become an emeritus professor in 1973. The Robert H. Breusch Prize in Mathematics, for the best senior thesis from an Amherst student, was endowed in his memory.
