Harold W. Kuhn

Harold William Kuhn (born 1925) is an American mathematician who studied game theory. He won the 1980 John von Neumann Theory Prize along with David Gale and Albert W. Tucker. A Professor-Emeritus of Mathematics at Princeton University, he is known for the Karush–Kuhn–Tucker conditions, for developing Kuhn poker as well as the description of the Hungarian method for the assignment problem. Recently, though, a paper by Carl Gustav Jacobi, published posthumously in 1890 in Latin, has been discovered that anticipates by many decades the Hungarian algorithm.

He is known for his association with John Forbes Nash, as a fellow graduate student, a lifelong friend and colleague, and a key figure in getting Nash the attention of the Nobel Prize committee that led to Nash's 1994 Nobel Prize in Economics. Kuhn and Nash both had long associations and collaborations with Albert W. Tucker, who was Nash's dissertation advisor. Kuhn co-edited The Essential John Nash, and is credited as the mathematics consultant in the 2001 movie adaptation of Nash's life, A Beautiful Mind.

His oldest son is historian Clifford Kuhn, noted for his scholarship on the American South and for collecting oral history. Another son, Nick Kuhn, is a professor of mathematics at the University of Virginia. His youngest son, Jonathan Kuhn, is Director of Art and Antiquities for the New York City Department of Parks & Recreation.
