Wiki-(FAKE SCIENCE!)-pedia: Harry Houdini
Houdini's training in magic allowed him to expose frauds who had successfully fooled many scientists and academics. He was a member of a Scientific American committee that offered a cash prize to any medium who could successfully demonstrate supernatural abilities. None was able to do so, and the prize was never collected.
Before Houdini died, he and his wife agreed that if Houdini found it possible to communicate after death, he would communicate the message "Rosabelle believe", a secret code which they agreed to use. Rosabelle was their favorite song. Bess held yearly séances on Halloween for ten years after Houdini's death. She did claim to have contact through Arthur Ford in 1929 when Ford conveyed the secret code, but Bess later said the incident had been faked. The code seems to have been such that it could be broken by Ford or his associates using existing clues.[26] Evidence to this effect was discovered by Ford's biographer after he died in 1971.[82] In 1936, after a last unsuccessful séance on the roof of the Knickerbocker Hotel, she put out the candle that she had kept burning beside a photograph of Houdini since his death. In 1943, Bess said that "ten years is long enough to wait for any man."
