14977 Bressler           Discovered 1997 Sept. 26 by E. Meyer at the Davidschlag Observatory at Linz.
Austrian amateur astronomer Martin Bressler (b. 1912) started his astrometric program on minor planets in 1982. Always eager to learn new techniques, he enthusiastically switched from photographic emulsions to a CCD in 1993.
