Encyclopedia
Leonard Mascot Blumenthal (February 27, 1901 – August 1984) was an 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.
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.
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.
