John Nash Dead: 'A Beautiful Mind' Mathematician Killed In Car Accident

Nobel Prize-winning mathematician John Nash was killed in a car accident on Saturday, New Jersey State Police told The Huffington Post.

The Princeton University scholar was 86 years old. His wife, Alicia, was also killed in the crash.

According to police, they were riding in a taxi on the New Jersey Turnpike and were ejected from the vehicle. NJ.com reports that Nash and his wife were not wearing seatbelts.

Nash was the subject of the Academy Award-winning film "A Beautiful Mind." The film depicted his groundbreaking work in game theory, for which he won the Nobel Prize in Economic Sciences in 1994. He also received the Abel Prize, one of mathematics' most prestigious honors, in March.

"A Beautiful Mind, " which starred Russell Crowe, also depicted Nash's struggles with mental illness. Nash suffered from schizophrenia and later in life became an advocate for improving mental health care.

"Stunned ... my heart goes out to John & Alicia & family," Crowe tweeted on Sunday. "An amazing partnership. Beautiful minds, beautiful hearts."
