John Nash

John Forbes Nash Jr. was an American mathematician who made fundamental contributions to game theory, real algebraic geometry, differential geometry, and partial differential equations. He served as a senior research mathematician at Princeton University from 1995 until his death in 2015. He is best known for his concept of the Nash equilibrium, which earned him the 1994 Nobel Prize in Economics, and his life was dramatized in the 2001 film A Beautiful Mind.
