John Nash, formally John Forbes Nash Jr., was an American mathematician who gave non cooperative game theory a rigorous mathematical foundation. In his 1950 Princeton PhD thesis he defined what is now called the Nash equilibrium and proved, using Kakutani's fixed point theorem, that every finite non cooperative game has at least one such equilibrium. He also did celebrated work in pure mathematics on real algebraic manifolds and nonlinear partial differential equations, winning the 1994 Nobel Memorial Prize in Economic Sciences for his game theory work and the 2015 Abel Prize for his mathematics.
