Saunders Mac Lane was a University of Chicago mathematics professor known for his pioneering work in category theory and leadership in the mathematics community.
R.P. Boas wrote in Mac Lane's Gung and Hu Distinguished Service to Mathematics Award citation,
His presidency made an enduring impression on those who were active in the Association at that time. He saw the office less as an honor than as an opportunity, attacked the problems of collegiate mathematics with characteristic imagination and energy, and set the Association on the active course that it has followed ever since.
Here are some of the activities that began under Mac Lane's presidency: the first steps were taken toward forming CUPM, and in particular toward improving the training of school teachers in mathematics; the Hedrick Lectures were invented; what is now the Employment Register was begun (by the MAA alone); the MAA and AMS began to cooperate in producing a Combined Membership List.
Mac Lane taught at Yale, Harvard, Cornell, and the University of Chicago before returning to Harvard in 1938 as an assistant professor. He then became a professor at the University of Chicago (1947-82; chair, 1952-58). After he retired, he advised two graduate students (1995 and 1997).
The Fiftieth Anniversary Issue of the American Mathematical Monthly included Saunders' remarks on "The Future Role of the Federal Government in Mathematics."
Mac Lane was a governor of the MAA in 1943-45 and vice president in 1948-49. He was also president of the AMS in 1973-74, vice president of the National Academy of Sciences, vice president of the American Philosophical Society, and a board member of the National Science Foundation. He was honored with the MAA Chauvenet Prize (1941), an AMS Colloquium Lecture (1963), the MAA Gung and Hu Distinguished Service to Mathematics Award (1975) the AMS Steele Prize for Lifetime Achievement (1986), and the National Medal of Science in 1989.
