This man invented the board games So Long Sucker and Hex, which was based on Go. With Moser, he generalized the inverse function theorem on Banach spaces to Frechet spaces. He also stated that any Riemannian manifold can be isometrically embedded in a Euclidean space in his namesake embedding theorem. Selten and Harsanyi shared a Nobel Prize with this man, which they won for developing the concept of a state in which no player in a game has anything to gain by unilaterally changing their strategy, this man's namesake equilibrium. For 10 points, identify this game theorist, whose schizophrenia was the subject of A Beautiful Mind.
