Sir Ernest Henry Shackleton

Shackleton, Sir Ernest Henry (1874–1922), Irish explorer who commanded 3 Antarctic expeditions (1907, 1914, 1921), the first of which came within 97 mi (156 km) of the South Pole and located the south magnetic pole. His 1914 expedition was marked by an open-boat crossing from Elephant Island to South Georgia Island and a winter traverse of that island's crest after his ship was crushed by ice. Written works include Heart of the Antarctic (1909), South: The Story of Shackleton's 1914–1917 Expedition (1919), and Adventure (1928).
