8409 Valentaugustus           Discovered 1995 Nov. 28 by R. Weber et al. at Socorro.
Valentin Augustus Weber (1867-1940) was a grandfather of the team leader. Born in Germany, he moved to the U.S. in 1889, where he designed and constructed stained-glass windows for cathedrals and mahogany furniture for his friends and neighbors in Brooklyn, New York.
