Lawrence Edward Grace "Titus" Oates or Captain Lawrence Oates (March 17, 1880 March 16, 1912) was a British cavalry officer and an Antarctic explorer. He died during the Terra Nova Expedition of 1910–13. Oates, who had gangrene and frostbite, walked from his tent into a blizzard. His death is seen as an act of sacrifice. When he knew that his sickness risked the survival of his three crew mates, he chose certain death.
