Genii, The Conjurors' Magazine is the longest-running independent magazine devoted to magic and magicians in the history of the art. It was founded by William W. Larsen, Sr. in 1936, and run by his descendents until 1998, when it was sold to The Genii Corporation, headed by well-known magic author Richard Kaufman. Genii is now a 112 to 120 page glossy color monthly and is edited by Richard Kaufman, with associate editor Jim Steinmeyer. The columnists include new additions Guy Hollingworth, Luke Jermay, Eugene Burger, and Harry Lorayne. Continuing columnists include David Acer, Michael Close, Bob Farmer, Jim Swain, Jon Racherbaumer, Jamy Ian Swiss, Eric Mead, David Oliver, David Regal, Danny Orleans, Dustin Stinett, Joe M. Turner and many others. Several times a year a free DVD or magic trick is included in the magazine—a first in the field of magic.
By the 1940s, the subscriptions had grown to several thousand throughout the world. In 1941, S.A.M. awarded Genii with the contract to print their [[M-U-M] as part of the magazine. This took away some of the Sphinx readership.
In 1942, Larsen purchased Floyd Thayer’s Magic Company. Genii did not turn into a "house organ" for the company but remained independent, even limiting the amount of advertising space given to Thayer’s. Even with having to devote time to the magic shop, shows, lectures, and his legal profession the magazine kept prospering.
In November, 1949, Genii absorbed The Conjurors' Magazine.
Bill and Milt both became involved in the new television industry and in 1962, The Academy of Magical Arts and The Magic Castle, originally Bill Sr.’s dream, were created. All Genii subscribers were automatic members. Genii, however, stayed independent of the Academy and the Castle.
Bill Larsen, Jr. became ill and the editorship of Genii was passed first by Dante Larsen (the son of Irene and her first husband John Daniel) and then to his daughter Erika Larsen. The magazine eventually started to falter as evident when only three issues were published in 1998.
In October 1998, the Larsens sold Genii to a new company headed Richard Kaufman. Beginning with the issue published by the newly formed Genii Corporation in January, 1999, Genii has been on time every single month.
