Sir Ernest Shackleton
Sir Ernest Henry Shackleton, CVO, OBE FRGS (15 February 1874 – 5 January 1922) was a polar explorer who led three British expeditions to the Antarctic, and one of the principal figures of the period known as the Heroic Age of Antarctic Exploration.
Born in County Kildare, Ireland, Shackleton and his Anglo-Irish family moved to Sydenham in suburban London when he was ten. His first experience of the polar regions was as third officer on Captain Robert Falcon Scott's Discovery Expedition, 1901–04, from which he was sent home early on health grounds. Determined to make amends for this perceived personal failure, he returned to Antarctica in 1907 as leader of the Nimrod Expedition. In January 1909, he and three companions made a southern march which established a record Farthest South latitude at 88° 23′ S, 97 geographical miles (112 statute miles, 180 km) from the South Pole, by far the closest convergence in exploration history up to that time. For this achievement, Shackleton was knighted by King Edward VII on his return home.
