RENEE MONTAGNE, HOST:
And now a remembrance. The mathematician and Nobel Laureate John Nash has died. He and his wife, Alicia, were killed in a car crash over the weekend. Nash's struggle with schizophrenia inspired the Oscar-winning film "A Beautiful Mind."

JOHN NASH: I was disturbed in this way for a very long period of time, like 25 years. And the movie gives an insight into how this sort of thing can go.
MONTAGNE: That's John Nash in 2004. He is best known for his work in game theory, considered one of the most influential economic ideas of the 20th century.

NASH: I don't think exactly like a professional economist. I think about economics and economic ideas but somewhat like an outsider.
MONTAGNE: When they died, John and Alicia Nash were returning from Norway where he received a mathematics prize. He was 86 years old. Transcript provided by NPR, Copyright NPR.
