Michael D. Morley

Morley was born in Youngstown, Ohio, on September 29, 1930.[1][2] He obtained his BS in mathematics from Case Institute of Technology in 1951 and his PhD in mathematics from the University of Chicago in 1962. Morley's formal PhD advisor at the University of Chicago was Saunders Mac Lane, but he completed his thesis under the guidance of Robert Vaught at the University of California, Berkeley.[1] His dissertation was titled Categoricity in Power.[3]

Morley was an assistant professor at the University of Wisconsin–Madison from 1963 to 1967. He joined the faculty at Cornell University in 1967 as an associate professor, was promoted to professor in 1970, and became a professor emeritus in 2003.[1] He served as president of the Association for Symbolic Logic from 1986 to 1989.[1]

Morley received the 2003 Leroy P. Steele Prize for Seminal Contribution to Research from the American Mathematical Society for his 1965 paper "Categoricity in Power". This paper, his doctoral dissertation, introduced Morley rank and proved Morley's categoricity theorem.[1][2]

Morley died on October 11, 2020, in Sayre, Pennsylvania.[1]
