'''[[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.
'''[[Ernest 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.


Dr. LeMasurier's work includes studying the origin and evolution of Cenozoic volcanic rocks, the nature of the tectonic environment of volcanism, and the volcanic record of glacial history.
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, then by launching the lifeboats to reach Elephant Island and ultimately the inhabited island of South Georgia, a stormy ocean voyage of 720 nautical miles and Shackleton's most famous exploit.


In 1990, after conducting a survey of [[Mount Berlin]], he declared the volcano to be "potentially active." Later, in 1994, during field work around [[Mount Siple]], Dr. LeMasurier knocked off a piece of rock from the mountain and sent it to Ruth Siple, the widow of [[Paul A. Siple]], for whom the mountain was named.
