Biography

Christiansen studied theology during 1904-1909 and worked as a language teacher for Finnish and Sami for priest sent to Finnmark, but he was not himself ordained as a priest.
Instead, he took an interest in folkloristics under the guidance of Moltke Moe.
He received a scholarship for a half-year's stay in Finland in 1912, where he studied under Kaarle Krohn. During 1914-1916 he studied in Copenhagen, studying under Axel Olrik. He also visited Lund University and studied under Carl Wilhelm von Sydow.
In 1919, Christiansen received money from the Nansen Fund to conduct field studies in Ireland and he published The Vikings and the Viking Wars in Irish and Gaelic Tradition in 1931 drawing on that research. He undertook to learn Irish, in Ballyferriter, Co. Kerry, at the suggestion of Carl Marstrander. In 1920, Osborn Bergin wrote a poem to Christiansen urging him to return to Ireland. He became archivist of the newly-established Norwegian National Archives in 1921.
Christiansen married Karin Lundbad, whom he had met in Lund, in 1921. The couple had five children, living in Blommenholm outside of Oslo.
Christiansen conducted comparative research in fairy tales, comparing the Scandinavian folklore and Irish folklore traditions in particular.
In his The Migratory Legends he proposed a type catalogue for the classification of "migratory legends", by motif, exemplified with examples from Norwegian folklore.
Christiansen became full professor for folkloristics at Oslo University in 1952. He was awarded an honorary doctorate from University College Dublin in 1954.
He retired in 1956 and spent a semester at Indiana University Bloomington at the invitation of Stith Thompson, and 1957/9 returned to Dublin, working with Seán Ó Súilleabháin. In 1958, he became chairman of the Commission International des Arts et Traditions Populaires of UNESCO.
He went on to publish his Studies in Irish and Scandinavian Folktales, European Folklore in America and Folktales of Norway.
