Louise Hay: 1935-1989, Robert I. Soare. Association for Women
in Mathematics Newsletter 20:1 (January-February 1990) 3-4.
The life and work of logician Louise Hay are described in this article.
Born in France in 1935, she came to America in 1946 and received a B.A. from Swarthmore College and her M.A. and Ph.D. from Cornell University.
Her doctoral dissertation dealt with recursive function theory. Initially on the faculty at Mount Holyoke College, she moved to the University of Illinois at Chicago in 1968 where she combined an active research career with teaching and administrative work. She succumbed to cancer in 1989.
Her research dealt with index sets connected with recursively enumerable sets
as well as with computational complexity theory. She was very influential in
encouraging women to pursue mathematical careers.
Apparently the Logic Seminar in Chicago is called the Louise Hay Seminar, if I'm not imagining things..
