Sixty years ago, on September 30, 1955, on a lonely stretch of two-lane highway in Northern California, James Dean was killed in a head-on collision. The Porsche Spyder 550 he was driving slammed into a Ford sedan when its driver did not see Dean coming and made a left-hand turn in front of him. In the violent wreck, Dean’s neck was broken. He died on impact. He was 24 years old.
