9399 Pesch           Discovered 1994 Sept. 29 by Spacewatch at Kitt Peak.
Peter Pesch (b. 1934), director of the Warner and Swasey Observatory during 1975--1994 and professor of astronomy at Case Western Reserve University during 1961--1997, is a leader in the search for unresolved blue objects (galaxies, QSOs and stars) through the use of low-dispersion prisms on the Burrell Schmidt Telescope.
