8847 Huch           Discovered 1990 Oct. 12 by F. Borngen and L. D. Schmadel at Tautenburg.
Named in honor of the German novelist and poet Ricarda Huch (1864-1947). Born into a prosperous commercial family, she earned a doctorate in history in Zurich in 1891, afterwards working as a librarian and teacher. In 1897 she decided to become a writer. Her novels and stories depict historical figures and events. She was a critic of the fascist regime, and her last unfinished work was to portray the German resistance movement. In 1933, she retired from the Prussian Academy of Arts. Name proposed by the first discoverer.
