Ernest Shackleton

Sir Ernest Henry Shackleton (15 February 1874 – 5 January 1922) was an Anglo-Irish Antarctic explorer who led three British expeditions to the Antarctic. He was one of the principal figures of the period known as the Heroic Age of Antarctic Exploration.

Born in Kilkea, County Kildare, Ireland, Shackleton and his Anglo-Irish family moved to Sydenham in suburban south London when he was ten. Shackleton's first experience of the polar regions was as third officer on Captain Robert Falcon Scott's Discovery expedition of 1901‍–‍1904, from which he was sent home early on health grounds, after he and his companions Scott and Edward Adrian Wilson set a new southern record by marching to latitude 82° S. During the Nimrod Expedition of 1907‍–‍1909, he and three companions established a new record Farthest South latitude of 88°23′ S, only 97 geographical miles (112 statute miles or 180 kilometres) from the South Pole, the largest advance to the pole in exploration history. Also, members of his team climbed Mount Erebus, the most active Antarctic volcano. On returning home, Shackleton was knighted for his achievements by King Edward VII.

After the race to the South Pole ended in December 1911, with Roald Amundsen's conquest, Shackleton turned his attention to the crossing of Antarctica from sea to sea, via the pole. To this end, he made preparations for what became the Imperial Trans-Antarctic Expedition of 1914‍–‍1917. The expedition was struck by disaster when its ship, Endurance, became trapped in pack ice and finally sank in the Weddell Sea off Antarctica on 21 November 1915. The crew escaped by camping on the sea ice until it disintegrated, then by launching the lifeboats to reach Elephant Island and ultimately the South Atlantic island of South Georgia, enduring a stormy ocean voyage of 720 nautical miles (1,330 km; 830 mi) in Shackleton's most famous exploit. He returned to the Antarctic with the Shackleton–Rowett Expedition in 1921 but died of a heart attack while his ship was moored in South Georgia. At his wife's request, he remained on the island and was buried in Grytviken cemetery. The wreck of Endurance was discovered just over a century after Shackleton's death.
