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]
