King and Queen of Norway, the University of Christiania, and the Danish Carlsberger Institute. His work was compiled in the Danish Folklore Archives, and was later transferred to the Royal Danish Library. Some of his recordings are housed at the Musée d'ethnographie de Neuchâtel. Leden wrote several articles that were published in journals, including "Christmas Among the Eskimos", "Trapping Salmon in the Far North", "A Chapter from my Eskimo Travels", and "Mobilizing the Arctic". The books he wrote, detailing his research, were published in German: Uber Kiwatins Eisfelder—Drei Jahre Unter Kanadischen Eskimos ("Across the Keewatin Icefields: Three Years Among the Canadian Eskimos, 1913-1916") Über die Musik der Smith Sund Eskimos und ihre Verwandtschaft mit der Musik der Amerikanischen Indianer Über die Musik der Ostgrönländer Bei den Indianern Kanadas Nanuk tauscht seine Frau When he finished his field work, the analysis and book writing, he traveled around the world, giving a series of lectures about his work. In the 1930s Leden became involved in Nazi German racial research, meeting with amongst others the leading Nazi racial theorist Hans F. K. Günther in Berlin. Leden joined the racial theorist organization Nordischer Ring c. 1930. He also had contacts with national socialist organizations both in Germany and Norway, including the SS Ahnenerbe think tank. He also worked for the Völkischer Beobachter, and in 1940 joined the foreign branch of the Norwegian national socialist party Nasjonal Samling. His Nazi connections is part of the reason his work is relatively unknown in Norway. Personal life Leden lost his autobiography twice. The first time, his pre-written manuscript was taken as evidence during the war because he had lived in Germany and had married a German woman. The second time, in the 1950s, his suitcase was stolen. When he sat down to write his autobiography for the third time, he did not complete it. He married Liselotte Steinicke (born 1904, Danzig, Germany - died 1998, Nesodden, Norway) in 1934 and they made their home in Berlin and Oslo. They had six children. Leden died in 1957.
