The Rosenheim Poltergeist is the conventional name for a cluster of alleged disturbances reported in and around a law office in Rosenheim, Bavaria, during 1967 and into the following period. It is important to treat the label as a later interpretive frame rather than as a demonstrated diagnosis. The core case consists of workplace testimony about anomalous telephone charges or connections, electrical and lighting irregularities, swinging fixtures, falling or moving objects, and episodes of apparent damage. The reports became unusually prominent because technical personnel, utility-related staff, police, journalists, and parapsychological investigators were said to have become involved, and because the case was subsequently associated with the German parapsychologist Hans Bender. Its reputation rests not on a single decisive experiment but on a mixed archive of recollection, professional observation, reported instrument readings, press attention, and later argument. Most narratives place the events in the office of lawyer Sigmund Adam. Accounts commonly identify a young office worker, usually named as Annemarie Schaberl, as being present during a conspicuous proportion of incidents. That pattern was important to investigators who interpreted it through the recurrent-spontaneous-psychokinesis model then common in poltergeist research: emotional strain in a focal person was proposed to be expressed as physical effects without conscious intent. The pattern is not itself evidence for such a mechanism. In an active office, a particular employee may be present because of work schedules, observers may selectively remember association after an event, and public identification of a junior worker can shape the story and create lasting reputational consequences. Reports that activity changed when the worker left, returned, or moved are therefore central claims requiring contemporaneous records, not settled facts. The electrical portion made Rosenheim appear more technically consequential than many domestic ghost stories. Recalled accounts describe lights that flickered, swung, or failed; bulbs or fittings that seemed to loosen; and voltage or electrical disturbances said to have been registered despite attempts at inspection. Telephone anomalies are likewise reported, including calls or charge units attributed to lines in the office when staff denied having made the relevant calls. These claims invited engineers into a field usually dominated by witness testimony, but technical involvement does not automatically convert a case report into a controlled test. To establish an unexplained physical effect, later reviewers would need the original meter traces, diagrams of the electrical installation, calibration and maintenance histories, telephone-provider logs, exact timing, access records, chain of custody, and an account of every intervention made while the office was being examined. The published or retold case is often stronger on the fact that experts were present than on the complete evidential materials needed to assess what those experts could actually exclude. The physical episodes are also heterogeneous. Some tellings refer to pictures, filing materials, furniture, drawers, or small office objects moving, falling, overturning, or being displaced. Others emphasize noise, lights, or telephones. Such variation may reflect multiple genuine but ordinary workplace incidents folded into one narrative, variations among witnesses, or later condensation of a long and confusing period into dramatic set pieces. It may also reflect deliberate action by an employee or visitor, whether playful, distressed, retaliatory, or intended to sustain attention. Fraud is a relevant hypothesis but should not be converted into an accusation against any particular person without direct evidence. Accidental mechanical causes are equally relevant: loose fittings, building vibration, wiring defects, defective switches, telephone-system faults, maintenance work, and normal failures can create a sequence that becomes more meaningful once witnesses expect further disturbances. Bender's role gives the case a second life as a parapsychological controversy. His standing and institutional connections made Rosenheim an attractive example for writers who argued that some poltergeist reports merit serious scientific attention. Skeptical writers, in turn, have treated it as an example of why the presence of instruments and educated observers is insufficient when a site remains open, many people can enter it, methods change during events, and purported anomalies are reported through incomplete documentation. The disagreement is not simply between people who believe in ghosts and people who do not. It concerns the proper threshold for attributing an observation to an unknown cause; the adequacy of controls in a functioning workplace; whether technical data were independently interpretable; and whether the narrative has separated primary records from later embellishment. The case belongs simultaneously to several genres. In local and popular terms it is a haunting or poltergeist story, with an office replacing the more familiar house. In parapsychological terms it is a putative recurrent-spontaneous-psychokinesis case associated with a possible focus person. In skeptical and engineering discussions it is a problem of diagnostics, access control, instrumentation, and the human tendency to join disparate anomalies into a single causal story. These genres each privilege different facts. A ghost-story retelling highlights dramatic movement and uncanny atmosphere. A parapsychological account highlights apparent witness corroboration, recurrence, and the association with Schaberl. A critical account highlights incomplete controls, possible ordinary faults, and the difference between an unexplained report and evidence for paranormal causation. Transmission has amplified the case's ambiguity. Contemporary publicity, later books, classroom examples, documentaries, online summaries, and lists of “best” poltergeist cases can circulate the same few episodes with altered quantities, dates, witness counts, and degrees of certainty. The name itself encourages compression: “the Rosenheim Poltergeist” sounds like a single entity, whereas the underlying material appears to be a sequence of claims made by different people using different kinds of evidence. Commercial and reputational incentives did not have to create the events to influence their presentation. A lawyer's office had an interest in resolving disruption and perhaps in managing publicity; newspapers had an interest in an unusual local story; investigators had an interest in a case bearing on their field; and later publishers had an interest in a memorable, technically flavored mystery. Those incentives are contextual cautions, not proof of deception. A responsible treatment therefore preserves two conclusions at once. First, the Rosenheim reports are historically significant within German parapsychology because they brought alleged physical phenomena in a modern office into contact with technical observers and public controversy. Second, the available recalled account does not establish that paranormal forces, ghosts, psychokinesis, or any other extraordinary mechanism occurred. The strongest research path is archival and comparative: recover the nearest contemporaneous documents; distinguish direct logs from recollections; reconstruct the building, phone, and power systems; identify who had access and when; compare the claims with known fault modes and social dynamics; and then state clearly which portions remain documented, merely reported, contradicted, or unknown.

Chronology
The case is generally dated to 1967, with reports placing its emergence during the latter part of that year in a Rosenheim legal office. The exact starting sequence, exact dates of individual incidents, and the order in which witnesses, technicians, police, journalists, and parapsychological investigators became involved require confirmation from contemporaneous records.
The reported period appears to have included recurring rather than continuously observed events. Retellings often present escalation from electrical and telephone irregularities to more visible physical disturbances, but that progression may be a narrative arrangement rather than a securely established event log.
Accounts generally place Hans Bender's interest or investigation after publicity and local concern had developed. Later circulation transformed the episode into a standard poltergeist case study, often omitting the distinction between original records, investigator interpretation, and secondary retelling.
People, Organisations, and Setting
The setting was reportedly a working law office in Rosenheim, Bavaria, rather than an isolated residence. That setting matters because it offered numerous potential witnesses and practical records, but it also introduced ordinary sources of complexity such as shared access, office routines, customer visits, electrical fixtures, telephones, repair work, and pressure to keep business operating.
The office is commonly associated with lawyer Sigmund Adam, while Annemarie Schaberl is commonly described in later case accounts as a young employee whose presence was linked to many incidents. The reported association made her a proposed focus person in parapsychological interpretations, but it does not establish agency, conscious or unconscious, or paranormal influence.
Hans Bender is the best-known investigator connected with the case in later literature. Local technical workers, telephone or electricity personnel, police, and journalists are also reported as participants or witnesses in some accounts, although the exact identities, roles, observations, and surviving records should be checked individually.
Reported Phenomena
Reported sensory and behavioural phenomena included lights flickering, lamps or fixtures swinging, bulbs or fittings apparently loosening, abrupt failures of electrical equipment, and unusual readings or fluctuations attributed to the office electrical supply. Witnesses may have interpreted repeated failures as coordinated because they occurred in an atmosphere of anticipation, but the original timing and equipment details are necessary to evaluate that interpretation.
Telephone reports included allegedly inexplicable calls, connections, or billing units associated with office lines. A telephone anomaly can be striking to occupants, yet possible explanations range from accounting or switching errors to line faults, cross-connections, misunderstood call records, unauthorised use, and later misunderstanding of what the bills recorded.
Physical incidents are variously recalled as objects, pictures, drawers, furniture, or office materials moving, falling, opening, overturning, or being damaged. Reports of movement should be separated into directly seen motion, an object found displaced after an interval, damage discovered after an interval, and accounts learned from another witness, because those categories have very different evidential value.
The alleged activity was reportedly intermittent and socially contagious in the ordinary sense that staff, visitors, and investigators discussed it while it was unfolding. Increased vigilance can improve detection of real faults, but it can also magnify ambiguous sounds, movements, and coincidences into a shared disturbance narrative.
Investigation History
The investigation history is usually described as beginning with practical efforts to identify electrical and telephone faults, followed by wider scrutiny after the reports attracted attention. This is a valuable feature of the case, because it implies that some claims may have generated records beyond personal testimony, but the existence, completeness, and independent interpretation of those records remain questions for verification.
Bender and colleagues reportedly treated Rosenheim as a potentially important parapsychological case. Their interpretive framework allowed for recurrent physical effects associated with a person under strain, an approach that can guide observation but can also bias investigators toward person-centred explanations when mundane technical or social causes have not been exhaustively eliminated.
A rigorous retrospective assessment would inventory each alleged event, its first recorder, exact time, location, relevant equipment, persons present, changes to the environment, and the contemporaneous explanation offered. It would then distinguish data that were instrumentally recorded and preserved from data that were only reported, and distinguish a failure to find a cause at the time from a positive finding of paranormal causation.
Disputes and Alternative Explanations
Supportive accounts emphasize the apparent diversity of effects, the number of observers, and reported technical investigation. Critical accounts respond that multiple reports can still derive from shared expectation, incomplete logging, uncontrolled access, ordinary mechanical defects, or a small number of misleading incidents repeated in later narration.
Technical alternatives include faulty wiring, defective fixtures, intermittent supply problems, loose hardware, vibration, switched circuits, telephone billing or routing errors, and repair-related changes. Each alternative fits some reported classes of event better than others, so no single mundane explanation should be asserted as conclusively resolving every claim without the primary evidence.
Social alternatives include misperception, memory convergence, workplace tension, prank or fraud, unacknowledged ordinary actions, and publicity feedback. These explanations do not require dishonesty by every witness, because sincere people can observe a real but ordinary occurrence and later incorporate it into an extraordinary shared account.
The key unresolved dispute is evidential rather than metaphysical. Later authors differ over whether the controls and documentation justify an anomalous residue after ordinary explanations, while critics argue that the surviving presentation does not permit that conclusion.
Transmission and Retellings
Rosenheim circulated from a local office disturbance into a prominent example in parapsychological and popular paranormal writing. In this transmission, a complicated set of reports became a portable case name that could be used to support positions about ghosts, psychokinesis, scientific openness, or skeptical method.
Later retellings commonly foreground dramatic electrical effects and the apparent presence of experts. They may reduce uncertainty around dates, instruments, personnel, and control conditions, which makes the case easier to remember but less useful as historical evidence.
Commercial and institutional influences are relevant to transmission. Newspapers, publishers, paranormal lecturers, skeptical authors, research institutions, and entertainment media all benefit in different ways from a vivid, unresolved case, so later popularity should not be confused with an increase in evidential quality.
Cross-Case Connections
Rosenheim connects to office and household poltergeist cases through motifs of recurrent disturbances, a proposed focus person, object displacement, electrical anomalies, and escalating witness attention. It differs from many traditional hauntings because its technical claims about power and telephones are central to its reputation.
It also connects to anomalous-technology narratives in which instruments seem to corroborate a strange event. Such cases are especially useful for comparison because instrumentation can clarify events only when calibration, preservation, access control, and independent interpretation are documented.
The case should be compared with workplace-rumour episodes and diagnostic failures as well as with paranormal reports. That wider comparison can test whether the same combination of ambiguous failures, social stress, attention, and retelling produces a “poltergeist” narrative without requiring an extraordinary cause.
Limits of This Dossier
This dossier is a recalled synthesis rather than a review of retrieved documents. It does not establish exact dates, equipment specifications, witness statements, institutional roles, or the contents of any technical report, and all such matters require source checking before use as evidence.
Names and associations included here are those commonly attached to the case in remembered accounts. Their spelling, role, chronology, consent, and the degree of their direct knowledge should be verified rather than inferred from secondary paranormal literature.
The absence of a settled mundane explanation in a summary would not demonstrate a paranormal explanation. Conversely, the plausibility of mundane explanations would not establish that any named individual deceived others, so both extraordinary claims and allegations of fraud require proportionate evidence.
