**Stephen H. Schanuel** (1933—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]}
