U.S. social scientist.
He received his Ph.D. from the University of Chicago in 1943. At Carnegie-Mellon University (from 1949), he taught psychology and later computer science. In Administrative Behavior (1947) Simon argued for recognizing a multiplicity of factors (including psychological ones) in corporate decision making rather than emphasizing the achievement of maximum profits as the primary motivation. He was awarded the Nobel Prize in Economics in 1978. He subsequently worked in the field of artificial intelligence using computer technology.
