Chattacon

Chattacon is an annual science fiction convention held in Chattanooga, Tennessee. The convention is organized by the nonprofit Chattanooga Speculative Fiction Fans, Inc. First held in 1976, the convention drew more than 1,200 attendees to the Chattanooga Choo Choo Hotel in 2014.

Chattacon was founded by Chattanooga native Irv Koch; the first Chattacon was held in January 1976. Formatted as a "relaxacon", it drew 81 guests, and lost money. By Chattacon III in 1978, it was a more traditional science fiction convention, with A. E. van Vogt as Guest of Honor, and had returned the costs of its original organization to Koch, with enough left over to serve as seed money for Chattacon IV.
