Crazy scientist Nash  
http://en.wikipedia.org/wiki/Nash_equilibrium#History
The contribution of John Forbes Nash, Jr. in his 1951 article Non-Cooperative Games was to define a mixed strategy Nash Equilibrium for any game with a finite set of actions and prove that at least one (mixed strategy) Nash Equilibrium must exist in such a game.

They married in February 1957 at a Catholic ceremony, although Nash was an atheist.
Nash experienced the first symptoms of mental illness in early 1959, when his wife was pregnant with their child. He resigned his position as member of the M.I.T. mathematics faculty in the spring of 1959.

Nash began to show signs of extreme paranoia, and his wife later described his behavior as erratic. Nash seemed to believe that all men who wore red ties were part of a communist conspiracy against him. Nash mailed letters to embassies in Washington, D.C., declaring that they were establishing a government.

Nash's wife admitted Nash to the McLean Hospital for schizophrenia in 1959; their son, John Charles Martin Nash, was born soon afterward.
Nash and de Lardé divorced in 1963, though after his final hospital discharge in 1970, Nash lived in de Lardé's house. They remarried in 2001.

Before his marriage, Nash also had a son named John David Stier from a relationship with Eleanor Stier, a nurse he met while she was caring for him as a patient.

In 1954, Nash was arrested for indecent exposure in a police trap in Santa Monica, California. Although the charges were dropped, he was stripped of his top-secret security clearance and fired from RAND Corporation where he had spent a few summers as a consultant.

Nash dates the start of what he terms "mental disturbances" to the early months of 1959 when his wife was pregnant.

Nash has suggested his delusional thinking was related to his unhappiness and his striving to feel important and be recognized, and to his characteristic way of thinking, saying, "I wouldn't have had good scientific ideas if I had thought more normally."

Nash reports that he did not hear voices until around 1964, later engaging in a process of rejecting them.

He reports that he was always taken to hospitals against his will, and only temporarily renounced his "dream-like delusional hypotheses" after being in a hospital long enough to decide to superficially conform – to behave normally or to experience "enforced rationality".
Only gradually on his own did he "intellectually reject" some of the "delusionally influenced" and "politically oriented" thinking as a waste of effort. However, by 1995, although he was "thinking rationally again in the style that is characteristic of scientists," he says he also felt more limited.


Writing in 1994, Nash stated:
"I spent times of the order of five to eight months in hospitals in New Jersey, always on an involuntary basis and always attempting a legal argument for release. And it did happen that when I had been long enough hospitalized that I would finally renounce my delusional hypotheses and revert to thinking of myself as a human of more conventional circumstances and return to mathematical research. In these interludes of, as it were, enforced rationality, I did succeed in doing some respectable mathematical research.
...
Then gradually I began to intellectually reject some of the delusionally influenced lines of thinking which had been characteristic of my orientation. This began, most recognizably, with the rejection of politically oriented thinking as essentially a hopeless waste of intellectual effort. So at the present time I seem to be thinking rationally again in the style that is characteristic of scientists.
