William Karush (1 March 1917 – 22 February 1997) was an American professor of mathematics at California State University at Northridge and was a mathematician best known for his contribution to Karush–Kuhn–Tucker conditions. In his master's thesis he was the first to publish these necessary conditions for the inequality-constrained problem, although he became renowned after a seminal conference paper by Harold W. Kuhn and Albert W. Tucker. He also worked as a physicist for the Manhattan Project, although he signed the Szilárd petition and became a peace activist afterwards.
