Rasmussen, Knud Johan Victor (1879-1933), a Danish explorer of Greenland. He was born in Greenland, and attended Copenhagen University. A trip to Lapland in 1901 helped prepare him for later expeditions across Greenland, to study the country and Eskimo life. Rasmussen founded Thule in 1910, and between 1912 and 1914 traveled more than 1,300 miles (2,100 km) over the ice, discovering a large area of ice-free land with much game. During his expedition of 1921-24, he made a thorough ethnological survey of Eskimo tribes.
