Knud Rasmussen

Danish explorer and anthropologist

The Fifth Thule Expedition, a massive research endeavor launched in 1921, stands as the crowning achievement of Knud Rasmussen, who sought to understand the origins of the Eskimo race. As an explorer and anthropologist of Danish and Greenlandic descent, he spent his life bridging the gap between Arctic cultures and the Western scientific establishment through rigorous, firsthand fieldwork.

Early Life and Education

Born in 1879 in Ilulissat, Greenland, Rasmussen was the son of a Danish missionary and an Inuk-Danish mother. His upbringing allowed him to gain fluency in the Kalaallisut language while mastering the skills necessary for Arctic survival, including hunting and dog sled operation. He later moved to Denmark to study at the University of Copenhagen, briefly attempting careers in opera and acting between 1898 and 1900 before dedicating his life to research.

Founding Thule

In 1910, Rasmussen founded the Thule Trading Station in North Star Bay near Mount Dundas with Peter Freuchen. This site served as the primary base for seven distinct Thule Expeditions conducted between 1912 and 1933. The first expedition in 1912 successfully disproved the theory that a channel separated Peary Land from the rest of Greenland, a feat of navigation across the inland ice that earned high praise from the Royal Geographical Society.

The Great Sled Journey

During the Fifth Thule Expedition, Rasmussen undertook an ambitious 16-month journey by dog sled across North America, eventually reaching Nome, Alaska. This expedition, which also included a brief period in Russia, established him as the first European to cross the Northwest Passage using a dog sled. He documented these experiences in the 1927 classic Across Arctic America, gathering extensive ethnographic data along the way.

Final Years and Legacy

Rasmussen’s career concluded with the Seventh Thule Expedition in 1933. While working on the screenplay for the film The Wedding of Palo, he contracted pneumonia following food poisoning caused by eating kiviaq. He died in Copenhagen at the age of 54. His extensive body of work, ranging from linguistic analysis to archaeological excavation, remains a foundational resource for Inuit studies, recognized by numerous honors including the Charles P. Daly Medal and the Hans Egede Medal.
