Herbert A. Simon
Herbert Alexander Simon (June 15, 1916 – February 9, 2001), a Nobel laureate, was an American political scientist, economist, sociologist, psychologist, and computer scientist whose research ranged across the fields of cognitive psychology, cognitive science, computer science, public administration, economics, management, philosophy of science, sociology, and political science, unified by studies of decision-making. With almost a thousand highly cited publications, he was one of the most influential social scientists of the twentieth century. For many years he held the post of Richard King Mellon Professor at Carnegie Mellon University
Simon was among the founding fathers of several of today's important scientific domains, including artificial intelligence, information processing, decision-making, problem-solving, organization theory, complex systems, and computer simulation of scientific discovery.
He coined the terms bounded rationality and satisficing, and was among the earliest to analyze the architecture of complexity and to propose a preferential attachment mechanism to explain power law distributions.
