Caitlyn Marie Jenner (born William Bruce Jenner; October 28, 1949) is an American television personality and retired Olympic gold medal–winning decathlete.
Jenner played college football for the Graceland Yellowjackets before incurring a knee injury that required surgery. Convinced by Olympic decathlete Jack Parker's coach, L. D. Weldon, to try the decathlon, Jenner won the men's decathlon event at the 1976 Summer Olympics in Montreal, setting a third successive world record and gaining fame as "an all-American hero".
Given the unofficial title of "world's greatest athlete", Jenner established a career in television, film, writing, auto racing, business, and as a Playgirl cover model.
