Lawrence Edward Grace “Titus” Oates [1880 – 1912] was a British army officer, and later an Antarctic explorer, who died from hypothermia during Robert Falcon Scott’s ill-fated expedition to the South Pole in 1911–1912. Oates walked from his tent into a blizzard on his 32nd birthday, in what is seen as an act of self-sacrifice. Oates was suffering from gangrene and frostbite, compromising his three companions’ chances of survival. According to the diary of Commander Robert Falcon Scott, CVO, [1868–1912], as Oates left the tent he said, “I am just going outside and may be some time.” The three other members of the party also perished over the next few days; Edgar Evans [1876-1912] had died previously.

Three mountains in the Whirlpool River valley were named in 1913 to commemorate men lost in the expedition. See Mount Scott.
