He was world-renowned for his work in logic, particularly as the founder of recursion theory. He was elected to the National Academy of Science in 1969; was awarded the American Mathematical Society Steele Prize in 1983 for his seminal papers of 1955 on recursion theory and descriptive set theory; and and in 1990 won the National Medal of Science, the country's highest scientific honour. Kleene was born in 1909 in Hartford Connecticut, received a Bachelor of Arts degree from Amherst in 1930, and a Ph.D. from Princeton in 1934 under the tutelage of Alonzo Church. Kleene first came to Madison in 1935 as an instructor and in 1937 was promoted to assistant professor. During the next several years he spent time at the Institute for Advanced Study in Princeton, taught at Amherst College, and served in the U. S. Navy, earning the rank of lieutenant commander during World War II. He returned to Madison in 1946, was promoted to full professor in 1948, and remained on the faculty for the remainder of his career. He became the C.C. MacDuffee Professor in 1964. He built a widely accclaimed logic group in the Mathematics Department, and served as chair of the Mathematics and Numerical Analysis (now Computer Science) departments. He also served as the Dean of the College of Letters and Science during the years 1969 to 1974. The Mathematics Department has established a Stephen Cole Kleene Memorial Fund in his honor. It is planned to have an invited Kleene Lecture approximately once a year and to sponsor other activities which Professor Kleene supported, such as scholarships and travel grants for graduate students. His colleagues in the Mathematics Department welcome your support in this endeavor and the support of your employer, should it have a policy of matching funds. * Contributions. Contributions can be sent to Stephen Cole Kleene Memorial Fund, UW Foundation, 1848 University Ave., Madison, WI 53705.
