Question: Which Norwegian explorer, who crossed Greenland in 1888, was best known for his "Fram" expedition?
Context: Giaever Glacier ( ) is a glacier flowing northwest between Mount Kerckhove de Denterghem and Mount Lahaye in the Belgica Mountains of Antarctica.  It was discovered by the Belgian Antarctic Expedition, 1957–58, under Gaston de Gerlache, who named it for Norwegian explorer John Schjelderup Giæver, counselor for the expedition, and leader of the Norwegian–British–Swedish Antarctic Expedition, 1949–52. Fridtjof Nansen ( ; 10 October 1861 – 13 May 1930) was a Norwegian explorer, scientist, diplomat, humanitarian and Nobel Peace Prize laureate.  In his youth he was a champion skier and ice skater.  He led the team that made the first crossing of the Greenland interior in 1888, traversing the island on cross-country skis.  He won international fame after reaching a record northern latitude of 86°14′ during his North Pole expedition of 1893–96.  Although he retired from exploration after his return to Norway, his techniques of polar travel and his innovations in equipment and clothing influenced a generation of subsequent Arctic and Antarctic expeditions. Andrew Kirkpatrick (born 24 June 1971 in Stafford , England), is a British mountaineer, author, motivational speaker and monologist.  He is best known as a big wall climber, having scaled Yosemite's El Capitan 29 times, including three solo ascents, and two one day ascents, as well as climbing in Patagonia, Alaska, Antarctica and the Alps.  He has also crossed Greenland by ski.  In 2014 he guided Alex Jones up Moonlight Buttress, Zion National Park, raising £1.9 million for Sport Relief. Nansen's "Fram" expedition was an 1893–1896 attempt by the Norwegian explorer Fridtjof Nansen to reach the geographical North Pole by harnessing the natural east–west current of the Arctic Ocean.  In the face of much discouragement from other polar explorers, Nansen took his ship "Fram" to the New Siberian Islands in the eastern Arctic Ocean, froze her into the pack ice, and waited for the drift to carry her towards the pole.  Impatient with the slow speed and erratic character of the drift, after 18 months Nansen and a chosen companion, Hjalmar Johansen, left the ship with a team of dogs and sledges and made for the pole.  They did not reach it, but they achieved a record Farthest North latitude of 86°13.6′N before a long retreat over ice and water to reach safety in Franz Josef Land.  Meanwhile, "Fram" continued to drift westward, finally emerging in the North Atlantic Ocean. Kristian Kristiansen (16 February 1865 - 30 June 1943) was a Norwegian explorer who participated in the Greenland expedition of 1888 arranged by Fridtjof Nansen.  This was the first documented crossing of Greenland. Fram (Norwegian for "Forward") is a 2008 play by Tony Harrison.  It uses the story of the Norwegian explorer Fridtjof Nansen's attempt to reach the North Pole, and his subsequent campaign to relieve famine in the Soviet Union to explore the role of art in a world beset by seemingly greater issues.  It is named after "Fram", the ship built for Nansen for his Arctic journey, and subsequently used by Roald Amundsen to reach the South Pole. Roald Engelbregt Gravning Amundsen (] ; 16 July 1872 – c. 18 June 1928) was a Norwegian explorer of polar regions.  As the leader of the Antarctic expedition of 1910–12, which was the first to reach the South Pole, on 14 December 1911, he was a key expedition leader during the Heroic Age of Antarctic Exploration.  In 1926, he was the first expedition leader for the air expedition to the North Pole, making him the first person, without dispute, to reach both poles.  He is also known as having the first expedition to traverse the Northwest Passage (1903–06) in the Arctic. Hong, Sung Taek (Hangul: 홍성택 ; Hanja: 洪成澤 ; born 13 March 1966) is a mountaineer, adventurer, explorer and author from South Korea.  He is currently a National Geographic Explorers supported by a National Geographic explorers program and a principal of KSAF Mountaineers Academy.  He is renowned for reaching all the Three Poles and crossing the Bering Strait and Greenland for the first time.  He summited Everest in 1995, skied to the South Pole in 1994 and walked to the North Pole in 2005.  He also crossed Bering Strait by foot in 2012 (official) and crossed Greenland by dog sledding in 2011.  He was thus the first in the world to reach all the five poles (Everest, North and South Poles, Bering Straits, Greenland). Oluf Christian Dietrichson (3 May 1856 – 20 February 1942) was a Norwegian explorer and military officer.  He was a member of the Greenland expedition of 1888 led by Fridtjof Nansen, the first documented crossing of Greenland. Eivind Astrup (] ; 17 September 1871 – 27 December 1895) was a Norwegian explorer and writer.  Astrup participated in Robert Peary's expedition to Greenland in 1891–92 and mapped northern Greenland.  In the follow-up Greenland expedition by Peary during 1893–94 he explored and mapped Melville Bay on the north-west coast of Greenland.  Among his works is "Blandt Nordpolens Naboer" from 1895 (English edition "With Peary near the Pole", 1898).  He was awarded the Knight of the Order of St. Olav in 1892.
