Warren Ambrose

Warren Arthur Ambrose (October 25, 1914 – December 4, 1995) was Professor Emeritus of Mathematics at the Massachusetts Institute of Technology and at the University of Buenos Aires.

He was born in Virden, Illinois in 1914. He received his bachelor of science degree in 1935, his master's in 1936 and his Ph.D. in 1939, all from the University of Illinois at Urbana–Champaign.

Personal life Warren Ambrose was a food and wine connoisseur, and also a fan of jazz saxophone player, Charlie "Bird" Parker. He is noted for his work with MIT colleague, Isadore Singer, both of whom helped to shape the pure mathematics department at MIT. He retired from teaching at MIT in 1985, thereafter moving to France. Ambrose died in 1995 in Paris. He was survived by his wife, Jeannette (Grillet) Ambrose of Paris, two children from an earlier marriage, Adam Ambrose of Bisbee, AZ, and Ellen Ambrose of Laurel, MD, and four grandchildren, Ambrose is often considered one of the fathers of modern geometry. He is noted for making changes in the pure mathematics undergraduate curriculum at MIT to reflect recent findings in differential geometry. For example, less than ten years after André Weil presented the differential form, Ambrose was using it in his undergraduate differential geometry courses. In the 1950s, Ambrose (together with I. M. Singer) made MIT into the only center in geometry in the United States outside the University of Chicago.

In 1967, Ambrose signed a letter declaring his intention to refuse to pay taxes in protest against the U.S. war against Vietnam, and urging other people to also take this stand.
