Founded in 1985, Pinball Expo is the longest-running event dedicated to pinball. It was conceived in 1984 by Robert "Rob" Berk of Warren, OH with the purpose of honoring his heroes of the pinball industry; the artists and designers. With the assistance of Bill Kurtz of Cleveland, OH and later Mike Pacak of Canfield, OH, the trio held their first event over the weekend of November 22–24, 1985 at the Holiday Inn O'Hare/Kennedy in Rosemont, IL. The inaugural event attracted around 100 attendees from all parts of the world and a dozen vendors. The expo offers seminars, a tour of a pinball factory, an autograph session, tournaments, an exhibit hall of pinball machines, parts, and related paraphernalia, and much more. On October 26, 1991, the Pinball Expo launched the Pinball Expo Hall of Fame and inducted its first class of pinball luminaries: David Gottlieb, Ray Moloney, Sam Stern, and Harry E. Williams. The event is open to the general public.
