Frank A. Worsley was the captain of the H.M.S. Endurance, the ship used by the legendary explorer Sir Ernest Shackleton in his 1914-16 expedition to the Antarctic. On its way to the Antarctic continent the Endurance became trapped and then crushed by ice, and the ship's party of twenty-eight drifted on an ice floe for five months. Finally reaching an uninhabited island, Shackleton, Worsley, and four others sailed eight hundred miles in a small boat to the island of South Georgia, an astounding feat of navigation and courage. All hands survived this ill-fated expedition; as Worsley writes, "By self-sacrifice and throwing his own life into the balance, [Shackleton] saved every one of his men…although at times it had looked unlikely that one could be saved."
