James Byron Dean (February 8, 1931 – September 30, 1955) was an American actor. He is remembered as a cultural icon of teenage disillusionment and social estrangement, as expressed in the title of his most celebrated film, Rebel Without a Cause (1955), in which he starred as troubled teenager Jim Stark. The other two roles that defined his stardom were loner Cal Trask in East of Eden (1955) and surly ranch hand Jett Rink in Giant (1956). After his death in a car crash, Dean became the first actor to receive a posthumous Academy Award nomination for Best Actor, and remains the only actor to have had two posthumous acting nominations. In 1999, the American Film Institute ranked him the 18th best male movie star of Golden Age Hollywood in AFI's 100 Years...100 Stars list.

In 1954, Dean became interested in developing an auto racing career. He purchased various vehicles after filming for East of Eden had concluded, including a Triumph Tiger T110 and a Porsche 356. Just before filming began on Rebel Without a Cause, he competed in his first professional event at the Palm Springs Road Races, which was held in Palm Springs, California on March 26–27, 1955. Dean achieved first place in the novice class, and second place at the main event. His racing continued in Bakersfield a month later, where he finished first in his class and third overall. Dean hoped to compete in the Indianapolis 500, but his busy schedule made it impossible.

Dean's final race occurred in Santa Barbara on Memorial Day, May 30, 1955. He was unable to finish the competition due to a blown piston. His brief career was put on hold when Warner Brothers barred him from all racing during the production of Giant. Dean had finished shooting his scenes and the movie was in post-production when he decided to race again.
