John Nash, the much famed American mathematician was killed along with his wife in a car crash in New Jersey on Sunday. The struggles with his mental health and his achievements became the subject of Sylvia Nasar's book titled "A Beautiful Mind", which was later adapted by Ron Howard into a motion picture of the same name. The film released in 2002 and Nash was portrayed by actor Russell Crowe. His death was condoled by many including the actor and director of his biopic. Our very own Prime Minister Narendra Modi also tweeted his sympathies for Nash and his wife's death.
