11847 Winckelmann           Discovered 1988 Jan. 20 by F. Borngen at Tautenburg.
The German art historian Johann Joachim Winckelmann (1717-1768) was the founder of classic archaeology. His passionate interpretation of Greek art defined the ideal of the beauty of classicism. His extensive knowledge of ancient art and culture is stated in his main work Geschichte der Kunst des Altertums.
