David Finlay Breashears (born December 20, 1955) is an American mountaineer, filmmaker, author, and motivational speaker. In 1985, he reached the summit of Mount Everest a second time, becoming the first American to reach the summit of Mount Everest more than once. He is perhaps best known as the director and cinematographer of Everest (1998)—which became the highest-grossing IMAX documentary—and for his assistance in the rescue efforts during the 1996 Everest disaster, which occurred during the film's production.
