71538 Robertfried           Discovered 2000 Feb. 5 by the Catalina Sky Survey.
Robert E. Fried (1930-2003), a former airline pilot, was inspired by Patrick Moore to build his own 16-inch telescope. Fried did professional quality photometry on variable stars from his Braeside Observatory, eventually located in Flagstaff, Arizona. He served as President of the Astronomical League from 1974-75 and 1977-78.
