40764 Gerhardiser           Discovered 1999 Oct. 13 at the Starkenburg Observatory, Heppenheim.
Gerhard Iser (b. 1962) was heavily involved with observations of minor planets at the Starkenburg Observatory during 1978-1982 and at that time was the mentor of Erwin Schwab, Jr., one of the discoverers of this minor planet. Iser is also an excellent photographer and performer on the harmonica.
