Canadian-born sleight-of-hand artist known as the Professor, who famously fooled Houdini and shaped modern close-up magic, including the card trick Triumph and an influential cups and balls routine.

Dai Vernon (1894–1992) was a Canadian-born magician, known to other magicians as the Professor, who did more than anyone in the twentieth century to shape modern close-up and card magic. He is famous for fooling Harry Houdini and for routines such as Triumph and his cups and balls.

Early life

He was born David Frederick Wingfield Verner in Ottawa on 11 June 1894. He took up magic as a boy and is said to have learned from the 1902 book The Expert at the Card Table, which he studied closely. The name Dai is usually explained as a misprint of Dave in an early newspaper notice, which he then kept; Verner became Vernon on stage.

In New York in the 1910s and 1920s he mixed with the best card handlers of the day while earning much of his living as a silhouette cutter, snipping profiles out of black paper for customers.

The man who fooled Houdini

Harry Houdini boasted that he could work out any card trick if he saw it three times. The story usually dated to 1922, in Chicago, is that Vernon showed him a version of the ambitious card, with a signed card returning to the top of the deck, again and again, and Houdini could not explain it. Vernon was billed for years afterwards as the man who fooled Houdini.

The Professor's work

Vernon was rarely a star of big theatres. His influence came through the magicians who watched him and the books written from his teaching, among them the Stars of Magic series of the 1940s and The Dai Vernon Book of Magic (1957), written by Lewis Ganson.

His central idea was naturalness: magic should look like nothing more than ordinary handling, with no visible effort. Pieces strongly linked to him include:

  • Triumph, in which a shuffled mix of face-up and face-down cards rights itself, all except the spectator's card
  • a cups and balls routine that many professionals still build on
  • a linking rings routine for close audiences

He also worked with and learned from Max Malini, and he spent years searching America for gamblers and card experts whose skill he had heard about.

The Magic Castle years

From the 1960s he lived in Los Angeles and was a fixture at the Magic Castle, the Hollywood club of the Academy of Magical Arts, where young magicians came to show him their work and hear his opinion. He held court there almost until his death on 21 August 1992, at the age of 98. For more on close-up work, see close-up magic and card magic for beginners.
