Midwestcon is an informal type of convention known as a relaxacon which means that it has no programming.
Instead, it is notable as a means for science fiction fans to get together and talk to each other without the distractions of other conventions.
The 1949 Worldcon took place in Cincinnati, and the first Midwestcon followed in 1950, and has been held every year since, making it the second longest-running SF convention to be held in the same city, and the third oldest in the U.S.
Many significant figures in science fiction have attended Midwestcon, including Isaac Asimov and Arthur C.
