Ferenc Dezső Weisz, known as Theodore "Dash" Hardeen, was a Hungarian-American magician and escape artist who was the younger brother of Harry Houdini. Hardeen, who usually billed himself as the "brother of Houdini", was the founder of the Magician's Guild. Hardeen was the first magician to conceive escaping from a straitjacket in full view of the audience, rather than behind a curtain.

Erik Weisz, known as Harry Houdini, was a Hungarian-American escape artist, illusionist, and stunt performer, noted for his escape acts.
