128065 Bartbenjamin           Discovered 2003 July 19 by B. L. Stevens at Desert Moon Observatory.
After joining the Peoria (Illinois) Astronomical Society, Bart Benjamin (b. 1958) became a curator at the Lakeview Museum of Arts and Sciences in Peoria, making astronomy exciting for the public. He eventually became director of the Cernan Earth and Space Center at Triton College in west suburban Chicago.
