Question: Bengt Emmerik Danielsson was a crew memeber on a 1947 expedition led by what explorer?
Context: Oviraptor is a genus of small Mongolian theropod dinosaurs, first discovered by technician George Olsen in an expedition led by Roy Chapman Andrews, and first described by Henry Fairfield Osborn, in 1924.  Its name is Latin for 'egg taker' or "egg seizer", referring to the fact that the first fossil specimen was discovered atop a pile of what were thought to be "Protoceratops" eggs, and the specific name "philoceratops" means "lover of ceratopsians", also given as a result of this find.  In his 1924 paper, Osborn explained that the name was given due to the close proximity of the skull of "Oviraptor" to the nest (it was separated from the eggs by only 4 in of sand).  However, Osborn also suggested that the name "Oviraptor" "may entirely mislead us as to its feeding habits and belie its character".  In the 1990s, the discovery of nesting oviraptorids like "Citipati" proved that Osborn was correct in his caution regarding the name.  These finds showed that the eggs in question probably belonged to "Oviraptor" itself, and that the specimen was actually brooding its eggs, when it died at the nest. The Shackleton–Rowett Expedition, 1921–22, was the last Antarctic expedition led by Sir Ernest Shackleton.  Proposed as an ambitious two-year programme of Antarctic exploration it was curtailed by the death of Shackleton and the inadequacies of the expedition's ship, "Quest".  Under the command of Frank Wild several attempts were made to break through the Antarctic pack ice, but the expedition was never able to proceed further than longitude 20°E. On the crew's return to Cape Town to refit in preparation for the second term they were ordered home.  The crew of the "Quest" comprised 24 members in all, but only 19 were on board for the start of the Antarctic portion (Hussey accompanied Shackleton's body when it was put on board a ship for England, and Eriksen, Mooney and Bee-Mason had left before the ship reached South Georgia).  Gerald Lysaght, a yachtsman, accompanied the crew from Plymouth to Cape Verde. Captain Sir Jameson Boyd Adams {'1': ", '2': ", '3': ", '4': "} (1880 – 1962) was a British Antarctic explorer and Royal Navy officer.  He participated in the Nimrod Expedition, the first expedition led by Ernest Shackleton in an unsuccessful attempt to reach the South Pole. Danger in the Pacific is a 1942 espionage thriller set on a fictional island during World War II.  As a cover for his true government mission, British intelligence agent Leo Marzell (Leo Carrillo) sponsors a scientific expedition led by Dr. David Lynd (Don Terry) to find a source for a wonder drug in the jungles of the South Pacific.  When Lynd agrees to the expedition over the objections of his aviator fiancée Jane Claymore (Louise Allbritton), she breaks the engagement but secretly follows him to the island.  Claymore attempts to halt Lynd's expedition so they can be married, but makes the mistake of recruiting Axis espionage agent Zambesi (Edgar Barrier) to help her.  Native islander Tagani (Turhan Bey) is sent by Zambesi to murder Lynd, and sets loose a tiger that injures Marzell.  Most of Lynd's guides are attacked by crocodiles, but one survives to kill Tagani.  Claymore ends up saving Marzall, Lynd and the remainder of the expedition by contacting the Royal Air Force which sends a rescue squad. Bengt Emmerik Danielsson (6 July 1921 – 4 July 1997) was a Swedish anthropologist and a crew member on the "Kon-Tiki" raft expedition from South America to French Polynesia in 1947. The goal of the Mallory and Irvine Research Expedition of 1999 was to discover evidence of whether George Mallory and Andrew Irvine had been the first to summit Mount Everest in their attempt of 8–9 June 1924.  The expedition was organized by regular Everest expedition leader Eric Simonson and advised by researcher Jochen Hemmleb, with a team of climbers from the U.S., the United Kingdom, and Germany.  Hemmleb's investigations of sketchy reports of earlier sightings and photographs had led him to identify what he believed was the area in which Irvine's body lay, some distance below where his ice axe had been found by Percy Wyn-Harris on the expedition led by Hugh Ruttledge in 1933.  The team hoped in particular to find a camera on Irvine's body which, had the pair been successful, should have contained a picture of the summit.  Within hours of commencing the search on 1 May 1999, Conrad Anker found a body on the North Face, at 8,155 m; but to their surprise it was that of Mallory, not Irvine. The "Kon-Tiki" expedition was a 1947 journey by raft across the Pacific Ocean from South America to the Polynesian islands, led by Norwegian explorer and writer Thor Heyerdahl.  The raft was named "Kon-Tiki" after the Inca sun god, Viracocha, for whom "Kon-Tiki" was said to be an old name. ""  is also the name of Heyerdahl's book; the Academy Award-winning documentary film chronicling his adventures; and the 2012 dramatised feature film nominated for the Academy Award for Best Foreign Language Film. Kon-Tiki is a Norwegian-Swedish documentary film about the Kon-Tiki expedition led by Norwegian explorer and writer Thor Heyerdahl in 1947, released in Sweden, Norway, Finland, and Denmark in 1950, followed by the United States in 1951.  The movie, which was directed by Thor Heyerdahl and edited by Olle Nordemar, received the Academy Award for Best Documentary Feature for 1951 at the 24th Academy Awards.  The Oscar officially went to Olle Nordemar.  It is currently the only feature film from Norway to have won an Academy Award. The Perry Expedition was a diplomatic expedition to Bakumatsu period Japan, involving two separate trips by warships of the United States Navy, which took place during 1853–54.  The goals of this expedition included exploration, surveying, and the establishment of diplomatic relations and negotiation of trade agreements with various nations of the region; opening contact with the government of Japan was considered a top priority of the expedition, and was one of the key reasons for its inception.  The expedition was commanded by Commodore Matthew Calbraith Perry, under orders from American President Millard Fillmore.  Perry’s primary goal was to force an end to Japan’s 220-year-old policy of isolation and to open Japanese ports to American trade, through the use of gunboat diplomacy if necessary.  The Perry Expedition led directly to the establishment of diplomatic relations between Japan and the western "Great Powers", and eventually to the collapse of the ruling Tokugawa shogunate. Hal Lister (1 May 192124 February 2010) was a British geographer and Arctic explorer.  Hal was born Harold Lister in Keighley, West Yorkshire, and was educated at Keighley Grammar School and King’s College (which later became Newcastle University).  In 1948, Hal guided a small group of Newcastle University Geography undergraduates on a pioneering overseas expedition to Iceland.  Hal joined the Merchant Navy, but transferred to the Royal Navy after learning to ﬂy.  He went to Fitzwilliam College, University of Cambridge in 1950 to do research in the Department of Geography, interrupted by his participation as a glaciologist in the British North Greenland Expedition, 1952–1954.  His Ph.D. was awarded in 1956.  Hal was a glaciologist during the Commonwealth Trans-Antarctic Expedition, 1955-1958.  During this expedition led by Sir Vivian Fuchs he helped to develop maps of the Weddell Sea.  Hal's last post was as a reader at the School of Geography, Newcastle University.  Hal formerly retired in 1986, but continued to travel widely and meet in academic circles until the last few years before he died on 24 February 2010.  One of his later interests was Amnesty International.
