Lange was born in Cloquet, Minnesota, on April 20, 1949. Her father, Albert John Lange (1913–1989), was a teacher and traveling salesman, and her mother, Dorothy Florence (née Sahlman; 1913–1998), was a housewife. Third of four children, she has two older sisters, Jane and Ann, and a younger brother named George. Her paternal ancestry originates in Germany and the Netherlands, while her maternal ancestry originates in Finland. Due to the nature of her father’s professions, her family moved over a dozen times to various towns and cities in Minnesota before settling back down in her hometown, where she graduated from Cloquet High School.
In 1967, she received a scholarship to study art and photography at the University of Minnesota, where she met and began dating Spanish photographer Paco Grande. After the two married in 1971, Lange left college to pursue a more bohemian lifestyle, traveling in the United States and Mexico in a minivan with Grande. The couple then moved to Paris, where they drifted apart. While in Paris, Lange studied mime theatre under the supervision of Étienne Decroux, and joined the Opéra-Comique as a dancer. She later studied acting at HB Studio in New York City.
