8827 Kollwitz           Discovered 1988 Aug. 13 by F. Borngen at Tautenburg.
Named for the distinguished German graphic artist and sculptor Käthe Kollwitz (1867-1945). She studied art in Berlin and Munich and was married to a physician. She became a professor and a member of the Prussian Academy of Arts in 1919 but was ousted in 1933. In her pictures, woodcuts, lithographs and sculptures, Kollwitz represented the destitution and misery of the poor, the unhappy fate of poor mothers and children, and the death of young men in war. She was deeply influenced by the tragedies of both world wars and the horrors of fascism, always hoping for a peaceful and humane society.
