Chicon I was sponsored by Illini Fantasy Fictioneer, a club set up for the purpose, and run by a triumvirate. Mark Reinsberg held the title of chairman (he'd won that title in a "bitter struggle" with W. Lawrence Hamling who claimed to have elected), with Erle Korshak (secretary and executive advisor) and Bob Tucker (treasurer and Director of the IFF) as equal partners. Sully Roberds did publications. Korshak presided over the opening day of the con, when Reinsberg fell ill.
The Chicon was also the place where Claude Degler made his first public appearance at a fannish event.
