Hartley Rogers Jr. (July 6, 1926 – July 17, 2015) was an American mathematician who worked in computability theory, and was a professor in the Mathematics Department of the Massachusetts Institute of Technology.
Early life and education
[edit | edit source]Born in 1926 in Buffalo, New York, Rogers studied English as an undergraduate at Yale University, graduating in 1946. After visiting the University of Cambridge under a Henry Fellowship, he returned to Yale for a master's degree in physics, which he completed in 1950. He studied mathematics under Alonzo Church at Princeton, earned a second master's degree in 1951,[1] and received his Ph.D. there in 1952.[2]
Career
[edit | edit source]He was a Benjamin Peirce Lecturer at Harvard University from 1952 to 1955. After holding a visiting position at MIT, he became a professor in the MIT Mathematics Department in 1956.[1] His doctoral students included Patrick Fischer, Louis Hodes, Carl Jockusch, Andrew Kahr, David Luckham, Rohit Parikh, David Park, and John Stillwell.[2] He chaired the MIT faculty senate from 1971 to 1973 and served as associate provost of the university from 1974 to 1980.[1]
Personal life
[edit | edit source]Beyond teaching and research, Rogers was an avid rower and rowing competitor.[1]
He retired as a professor emeritus in 2009, and died on July 17, 2015.[1]
Mathematical work
[edit | edit source]Rogers worked in mathematical logic, particularly recursion theory, and wrote the classic text Theory of Recursive Functions and Effective Computability.[3] The Rogers equivalence theorem is named after him.
Rogers won the Lester R. Ford Award in 1965 for his expository article Information Theory.[4]
