Leonard Mascot Blumenthal (February 27, 1901 - August 1984) was a Jewish[1] American mathematician.
He received his Ph.D. in 1927 from Johns Hopkins University, under the supervision of Frank Morley; his dissertation was titled Lagrange Resolvents in Euclidean Geometry. He taught for the majority of his professional career at the University of Missouri and was the author of A Modern View of Geometry.[2]
He was a visiting scholar at the Institute for Advanced Study from 1933 to 1936.[3] According to the Mathematics Genealogy Project, he had 18 Ph.D. students at Missouri, among them Leroy Milton Kelly and William Arthur Kirk; he is the academic ancestor of over 80 mathematicians.[4]
The Leonard M. Blumenthal Distinguished Professorship in Mathematics at the University of Missouri was established in 1992 in honor of Blumenthal. This endowed chair is given on a five-year rotating basis to Missouri mathematics professors; the Blumenthal Professors at Missouri have included John Beem, Mark Ashbaugh, Alex Koldobsky, and Zhenbo Qin.[5] The American Mathematical Society also issued the Blumenthal Award in his honor.
