Ernest Shackleton
Ernest Shackleton, Anglo-Irish explorer of the Heroic Age from 1874 to 1922, marched to within 112 miles of the South Pole on the Nimrod expedition in 1909, moving Amundsen to declare in 1911 that his name would stand 'in letters of fire' in the annals of Antarctic exploration. When pack ice crushed the Endurance in the Weddell Sea, he sailed 800 miles in the 22-foot James Caird to bring rescue to his stranded crew.
