Theodore "Ted" Judd Serios (November 27, 1918 – December 30, 2006) was a Chicago bellhop known for his production of "thoughtographs" on Polaroid film. He claimed these were produced using psychic powers. Serios's psychic claims were bolstered by the endorsement of a Denver-based psychiatrist, Jule Eisenbud (1908–1999), who wrote a book called The World of Ted Serios: "Thoughtographic" Studies of an Extraordinary Mind (1967) arguing that Serios's purported psychic abilities were genuine. However, professional photographers and skeptics have debunked Serios and his photographs as fraudulent.
