John Nash, the Nobel Prize-winning mathematician whose life inspired the acclaimed 2001 film A Beautiful Mind, was killed in a car accident in New Jersey on Saturday. He was 86 years old.
Nash's wife, Alicia, was also killed in the crash.
Police say the couple was riding in a taxi without seatbelts and were thrown from the vehicle when it struck a guardrail.
Nash was best known for his work with game theory and he was awarded the Nobel Prize for Economics in 1994.
The Ron Howard-directed biopic about Nash's life depicted not only his mathematical brilliance, but also his lifelong struggle with schizophrenia.
A Beautiful Mind went on to win four Academy Awards, including Best Picture.
Moments ago, Russell Crowe, who portrayed Nash in the film, tweeted, "Stunned...my heart goes out to John & Alicia & family. Beautiful minds, beautiful hearts."
In their later years, the Nashes devoted themselves to working with mental health advocacy groups.
Jennifer Connelly won an Oscar for her her portrayal of Alicia Nash in the movie that made the couple household names outside of the mathematics community.
