11061 Lagerlöf           Discovered 1991 Sept. 10 by F. Borngen at Tautenburg.
Swedish novelist Selma Lagerlöf (1858-1940) wrote beautiful stories, using popular tales of her Vaermlandian homeland. She dealt with social problems, questions of fault and responsibility from a religious-ethical point of view. Awarded the Nobel prize for literature in 1909, she was the first female member of the Swedish Academy.
