Colin Evans (medium)
In a flash-illuminated picture taken at a séance in Wortley Hall, Finsbury Park in 1937 Evans can be seen "levitating" in mid air. He claimed that spirits had lifted him. Evans was later discovered to be a fraud as a cord leading from a device in his hand has indicated that it was himself who triggered the flash-photograph and that all he had done was jump from his chair into the air and pretend he had levitated. He performed in complete darkness so that sitters in the séance could not see what he was doing. Magicians have pointed out that Evan's blurred feet in the photographs are proof that he simply jumped high into the air.
