James Robert Slagle (March 1, 1934 – December 3, 2023) was an American computer scientist notable for his many achievements in Artificial Intelligence. Since 1984 he has been the Distinguished Professor of Computer Science at the University of Minnesota, Minneapolis, with former appointments at Johns Hopkins University, the National Institutes of Health (Bethesda, Maryland), the Naval Research Laboratory, Lawrence Radiation Laboratory, University of California and the Massachusetts Institute of Technology.

In 1961 in his dissertation at the Massachusetts Institute of Technology with Marvin Minsky, Slagle developed the first expert system, SAINT (Symbolic Automatic INTegrator), which is a heuristic program that solves symbolic integration problems in freshman calculus.^[1] Remarkably, among other recognitions, President Dwight D. Eisenhower awarded him $500 for his outstanding work as a blind student.^[1]

Slagle died in Bethesda, Maryland on December 3, 2023, at the age of 89.^[2]
