The Rosenheim poltergeist investigation

Record summary

At a lawyer’s office in Rosenheim, reports included unexplained telephone calls, electrical irregularities, moving objects and damaged fixtures. Physicist John G. F. Zöllner and parapsychologist Hans Bender became associated with investigations, while later discussions questioned controls, documentation and possible human involvement. The case matters because it was presented as a technically monitored workplace anomaly rather than a traditional haunted house. Researchers should consult German-language reports and later skeptical analyses, since summaries often omit the limitations of the observations and the dispute over what was actually measured.
