Undset was born in Kalundborg, Denmark, but her family moved to Norway when she was two years old. In 1924, she converted to Catholicism. She fled Norway for the United States in 1940 because of her opposition to Nazi Germany and the German invasion and occupation of Norway, but returned after World War II ended in 1945.
