Shackleton, Sir Ernest Henry (1874-1922), an Irish explorer, led a British expedition from the Ross Sea that came within 97 nautical miles (180 kilometers) of the south geographic pole in 1908 (see Antarctica). In 1914, he led an expedition into the Weddell Sea, where ice crushed his ship, the Endurance. His party escaped in boats to Elephant Island. Shackleton and five companions then made a daring journey by boat to South Georgia Island and crossed the island's glacier-covered mountainous ridge to summon rescuers. As a result, his entire party was saved. Shackleton was born on Feb. 15, 1874, in County Kildare. He wrote Heart of the Antarctic (1909) and South (1919). He died on Jan. 5, 1922.
