4525 Johnbauer           Discovered 1982 May 15 by E. F. Helin, E. M. Shoemaker and P. D. Wilder at Palomar.
John Bauer (1932-2003), who taught astronomy and physics at San Diego City College for 37 years, dedicated his life, not to making discoveries himself, but to inspiring hundreds of students to pursue astronomical careers, helping them succeed and supporting their scientific goals. The name was suggested by N. Butler.
