9240 Nassau           Discovered 1997 May 31 by Spacewatch at Kitt Peak.
Jason J. Nassau (1893-1965) was director of the Warner and Swasey Observatory and professor at Case Institute of Technology during 1924--1959. A pioneer in studies of galactic structure and early proponent of Schmidt telescopes, he led the effort to build the 61/91-cm Burrell Schmidt telescope, now located at Kitt Peak.
