Sir '''[[Ernest Shackleton|Ernest Henry Shackleton]]''' was a polar explorer who led three British expeditions to the [[Antarctica|Antarctic]], and one of the principal figures of the period known as the Heroic Age of Antarctic Exploration. His first experience of the polar regions was as third officer on Captain [[Robert Falcon Scott]]'s Discovery Expedition 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.

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, 1914–17. Disaster struck this expedition when its ship, ''[[Endurance]]'', became trapped in [[pack ice]] and was slowly crushed before the shore parties could be landed. The crew escaped by camping on the sea ice until it disintegrated.

Away from his expeditions, Shackleton's life was generally restless and unfulfilled. In his search for rapid pathways to wealth and security, he launched business ventures which failed to prosper, and he died heavily in debt.

Wesley E. LeMasurier is an igneous petrologist/volcanologist who specializes in the study of Cenozoic volcanoes in the Marie Byrd Land region of Antarctica. He was responsible for geological research around many of Westarctica's volcanic mountains. Mount LeMasurier was named in his honor.
