Who is shackelton?

Answer 1

Shackleton organized and led the "British Antarctic Expedition" (1907-1909) to Antarctica. The primary and stated goal was to reach the South Pole. The expedition is also called the Nimrod Expedition after its ship, and the "Farthest South" expedition. Shackleton's base camp was built on Ross Island at Cape Royds, approximately 20 miles (40 km) north of the Scott's Hut of the 1901-1904 expedition; the hut built at this camp in 1908 is on the list of the World Monuments Watch's 100 most endangered sites. Because of poor success with dogs during Scott's 1901-1904 expedition, Shackleton used Manchurian ponies for transport, which did not prove successful.

also,

Shackleton, with Wild, Marshall, and Adams, reached 88°23'S: a point only 180 km (97 nautical miles) from the South Pole. While the expedition did not make it to the pole, nonetheless, Shackleton, Adams, Marshall, and Wild were the first humans to not only cross the Trans-Antarctic mountain range, but also the first humans to set foot on the South Polar Plateau.

cool, huh.
