The Rosenheim Poltergeist is the name given to claims of a poltergeist in Rosenheim in southern Bavaria in the late 1960s by German parapsychologist Hans Bender. Bender alleged that electrical and physical disturbances in the office of the lawyer Sigmund Adam were caused by the telekinetic powers of 19-year-old secretary Annemarie Schaberl. Bender's investigation has been criticized for omitting key details and avoiding naturalistic explanations.
According to Bender, in the Fall of 1967 he was requested to investigate disturbances in Adam's legal offices which reportedly occurred only on weekends. It was claimed that lighting fixtures exploded, swung back and forth or had their bulbs removed, heavy office furniture was shifted, and copier fluid leaked from the office copier. Additionally, the staff denied having made a large number of outgoing calls to a correct time service that were charged to the firm's telephone company account. The electric company reported evidence of malfunctions due to substantial surges in the power system, and Bender alleges that unspecified tests were made by physicists Friedbert Karger and Gerhard Zicha who reported that "some unknown form of energy is at work." Bender claimed that a heavy filing cabinet was reported to have been pushed across the floor by an invisible force, and that a framed painting was captured on film "rotating around its hook." Calling her "a typical poltergeist", Bender believed that the emotional unhappiness of Annemarie Schaberl, a young secretary at the firm, was "converted into psychokinesis." He said that Schaberl told him she was frustrated with her job and distressed over a broken marriage engagement. According to Bender, the alleged poltergeist activity ceased when Schaberl left the law firm and was married.
In April 1970 a story in the German weekly newspaper Die Zeit reported that co-authors Albin Neumann (Allan), Herbert Schiff, and Gert Gunther Kramer suggested in their book "Falsche Geister, echte Schwindler?" ("False spirits, real swindlers?") that the claims of unexplained disturbances initially made by Adam were fraudulent. The authors wrote that they visited Adam's law offices and discovered nylon threads attached to office fixtures such as overhead lights and wall plates that, when pulled, would cause the fixtures to move, and concluded that "the public had been tricked by tricks." Adam reportedly filed a legal injunction to stop publication of the book, which was not granted, and further hearings were scheduled in the District Court of Traunstein.
