Alfred Clifford
Alfred "Al" Hoblitzelle Clifford (born July 11, 1908 in St. Louis , † December 27, 1992 ) was an American mathematician who mainly dealt with semigroups .
Clifford grew up in California and studied mathematics at Yale University with a bachelor's degree in 1929. He received his doctorate in 1933 with Eric Temple Bell at Caltech with a dissertation on arithmetic and ideal theory of abstract multiplication ( Arithmetic of Ova ). He then spent five years at the Institute for Advanced Study , from 1936 to 1938 as assistant to Hermann Weyl , whom he helped with the publication of The Classical Groups . During this time he mainly dealt with group theory. In 1938 he became an instructor and in 1941 an assistant professor at the Massachusetts Institute of Technology . In 1941 there was an important and influential work on semigroups. After military service as an officer in World War II (in Europe and Washington, during which time he published nothing) he taught as an associate professor at Johns Hopkins University , which was interrupted by military service in the Korean War from 1950 to 1953. From 1955 he was a professor at Tulane University . In retirement, he lived in California again.
He was invited speaker at the International Congress of Mathematicians in 1950 and 1974. He received an honorary doctorate from Tulane University in 1982.
He was a talented pianist who also composed.
