57868 Pupin           Discovered 2001 Dec. 17 by NEAT at Palomar.
Mihajlo Pupin (1858-1935) was a Serbian-American physicist and humanitarian. He greatly improved long-distance telephone transmission and the sensitivity of X-ray detection, and worked for Serbian emigres. Name suggested by V. Benishek and F. Pilcher, who obtained the first rotational lightcurves for this object.
