The Rosenheim poltergeist case

Record summary

The Rosenheim poltergeist concerned alleged telephone, electrical, and physical disturbances in the law office of Sigmund Adam in Rosenheim during 1967. Physicist and parapsychologist Hans Bender investigated, and reports describe instrument readings, utility records, and staff testimony. The case is useful for comparison because it involved an active workplace, technical documentation, and claims of recurrent anomalies rather than a purely folkloric haunted house. Researchers should consult German-language primary or contemporary sources and examine disputed controls, witness access, and possible ordinary interference.
