John Nevil Maskelyne (born December 22, 1839, Cheltenham, Gloucestershire, England—died May 18, 1917, London) was a British magician whose inventions and patronage of new performers greatly influenced the development of the art of producing illusions by sleight of hand.
Trained as a watchmaker, Maskelyne became famous in 1865 when he, aided by George A. Cooke, exposed the Davenport Brothers as fraudulent spiritualists. For eight years he and Cooke performed a show featuring Maskelyne’s box trick, juggling, and automata. After Cooke died in 1904, Maskelyne took as a partner David Devant, the most famous magician in England. Maskelyne’s son Nevil collaborated with Devant on Our Magic (1911), an important source book on the theory of magic.
