39930 Kalauch           Discovered 1998 Mar. 24 by G. Lehmann at Volkssternwarte Drebach.
While still a student, Klaus-Dieter Kalauch (b. 1958), amateur astronomer and teacher of astronomy, understood how to inspire his friends with the beauty of the sky. Without his influence, the discoverer would never have become interested in observing minor planets.
