Ed Balducci published the first known description of the illusion in July 1974 in The Pallbearer's Review, (Volume 9, Number 9, pp 755) under the name "Impromptu Levitation." Balducci ended his description by saying, Originator unknown. It was shown to me many years ago by one of the Harmonicats, a cousin of mine, Erwin Levine, known as the Baron.
Despite Balducci's disclaimer, the illusion has since been known as the "Balducci Levitation."
