Stephen H. Schanuel (14 July 1933 – 21 July 2014) was an American mathematician working in the fields of abstract algebra and category theory, number theory, and measure theory. [1] [2]

Life

While he was a graduate student at University of Chicago, he discovered Schanuel's lemma, an essential lemma in homological algebra. [2] Schanuel received his Ph.D. in mathematics from Columbia University in 1963, under the supervision of Serge Lang. [2]

Work

Shortly thereafter he stated a conjecture in the field of transcendental number theory, which remains an important open problem to this day. [2] Schanuel was a professor emeritus of mathematics at University at Buffalo. [1]
