10430 Martschmidt           Discovered 1960 Sept. 24 by C. J. van Houten and I. van Houten-Groeneveld on Palomar Schmidt plates taken by T. Gehrels.
Maarten Schmidt (b. 1929) is a famous Dutch-American astronomer. His identification of the wavelengths of the radiation emitted by quasars led to the theory that they may be among the most distant and the oldest objects ever observed. The name was suggested by W. A. Fröger and H. Habing.
