7749 Jackschmitt           Discovered 1988 May 12 by C. S. Shoemaker and E. M. Shoemaker at Palomar.
Named in honor of Harrison Schmitt (b. 1935), the last Apollo astronaut to walk on the moon and, as a planetary geologist, the only Apollo scientist. Schmitt later served as a member of the United States Senate from New Mexico.
