Brother John Charles Hamman S.M. (September 3, 1927 – December 5, 2000) was a close-up magician and Marianist Brother. The tricks he invented are still an integral part of many close-up magician's repertoire. Hamman was world-renowned in the magic community. His initial interest in the art started as a child. As he recuperated from polio, he spent hours learning, practicing and inventing card tricks and other magic involving sleight-of-hand. In many cases, he "reinvented" classic maneuvers or streamlined them. He was a member of the International Brotherhood of Magicians, the Catholic Magicians' Guild and the Society of American Magicians.
