Michael D. Morley

Michael Darwin Morley ( b. 1930 in Youngstown, Ohio) is an American mathematician who deals with mathematical logic (model theory).

Morley studied at the Case Institute of Technology ( bachelor's degree in 1951 ) and worked from 1955 to 1961 at the Laboratory for Applied Sciences of the University of Chicago. In 1962 he received his doctorate at the University of Chicago with Robert Vaught and then was Instructor at the University of California, Berkeley. In 1963 he was Assistant Professor at the University of Wisconsin and from 1966 at Cornell University, where he 's Director of Undergraduate Studies was in mathematics from 1984 to 1995 and 2002 was Professor Emeritus.

In his thesis he proved an important set of Morley model theory: A countable theory has a unique model in an uncountably infinite cardinality, has a unique model in any other uncountably infinite cardinality. For this he received the 2003 Leroy P. Steele Prize. 1986 and 1989 he was president of the Association for Symbolic Logic.
