Rosenheim, Germany (1967)
Main article: Rosenheim Poltergeist
Dr. Friedbert Karger was one of two physicists from the Max Planck Institute who helped to investigate perhaps the most validated poltergeist case in recorded history. Annemarie Schneider, a 19-year-old secretary in a law firm in Rosenheim (a town in southern Germany) was seemingly the unwitting cause of much chaos in the firm, including disruption of electricity and telephone lines, the rotation of a picture, swinging lamps which were captured on video (which was one of the first times any poltergeist activity has been captured on film), and strange sounds that sounded electrical in origin were recorded. Fraud was not proven despite intensive investigation by the physicists, journalists, and the police. The effects moved with the young woman when she changed jobs until they finally faded out, disappeared, and never recurred.
In the Rosenheim case of 1967, [7] The Rosenheim Poltergeist (1967),[8][9][10] Friedbert Karger's whole perspective on physics changed after investigating the events. "These experiments were really a challenge to physics," Karger says today. "What we saw in the Rosenheim case could be 100 per cent shown not to be explainable by known physics."[11] The phenomena were witnessed by Hans Bender, the police force, the CID, reporters, and the physicists. The case was made into a documentary by the BBC in 1975 as part of a TV series called "Leap in the Dark.
