The Tenth World Science Fiction Convention was held on Labor Day weekend in August 1952 at the Morrison Hotel in Chicago, Illinois. Unlike most worldcons before or since, it did not have a specific title other than the World Convention (of other Worldcons, only the 11th, in Philadelphia in 1953, shared this lack of name), although it was informally known by its acronym, TASFiC or as Chicon II (the eleventh convention is similarly occasionally referred to as Philcon II).
