Clark N. Glymour, born in 1942, is an American philosopher currently serving as the Alumni University Professor Emeritus in the Department of Philosophy at Carnegie Mellon University. He also holds the position of Senior Research Scientist at the Florida Institute for Human and Machine Cognition. Glymour earned undergraduate degrees in chemistry and philosophy from the University of New Mexico before obtaining his Ph.D. in History and Philosophy of Science from Indiana University Bloomington in 1969. He is recognized as the founder of the Philosophy Department at Carnegie Mellon University. His academic achievements include being a Guggenheim Fellow, a Fellow of the Center for Advanced Study in Behavioral Sciences, and a Phi Beta Kappa lecturer. Glymour's significant contributions include the causal interpretation of Bayes nets and the development of the TETRAD algorithm for causal inference, which he co-developed with Peter Spirtes and Richard Scheines. His research interests span epistemology, machine learning, automated reasoning, and the psychology of judgment. A notable contribution is his analysis of the Bayesian "problem of old evidence." The PC algorithm, used in learning the structure of Bayesian networks, is named in part after him.
