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]
