Trenton (US): John Forbes Nash Jr, a mathematical genius whose struggle with schizophrenia was chronicled in the  2001 movie "A Beautiful Mind," has died along with his wife in a car crash on the New Jersey Turnpike. He was 86.

Nash and Alicia Nash, 82, of Princeton Township, were killed in a taxi crash yesterday, state police said. A colleague  who had received an award with Nash in Norway earlier in the week said they had just flown home and the couple had taken a cab home from the airport.
