12568 Kuffner           Discovered 1998 Nov. 11 by K. Korlevic at Visnjan.
Moriz von Kuffner (1854-1939) was a brewer, alpinist and the founder of a private observatory in Vienna. The Kuffner Observatory was a leading scientific institution in the late nineteenth century and is now used for public education. It is serving as host for the May 2006 Meeting on Asteroids and Comets in Europe.
