Katie King

Within Spiritualist accounts of the 1870s, Katie King is the persistent spirit personality or 'control' named and produced in physical‑medium séances, particularly those involving the medium Florence Cook. Sources present this origin as a claim by Spiritualists rather than an independently corroborated historical fact; the sittings and the spirit's appearances became a focal point for mid‑1870s public debate and investigation (including inquiries by figures such as William Crookes, as reported in contemporary accounts and later summaries).

Spiritualist sources describe Katie King as a materialized female spirit figure manifesting in the séance room as a bodily presence produced through mediumship. Precise contemporaneous descriptive details (dress, exact features, height) vary across accounts and are contested; the supplied materials consistently present her as a purportedly fully materialized spirit rather than merely an unseen voice or trance control.

According to Spiritualist testimony of the 1870s, Katie King manifested by physical materialization in séance conditions and could interact with sitters and investigators as a person in the séance room. The historical record emphasizes that these claims were disputed: investigators and skeptics accused mediums and their controls of fraud, while Spiritualists maintained the independent personality and corporeal appearance of Katie King. The phenomenon therefore is documented as a produced séance manifestation that attracted scientific and legal scrutiny rather than as an established supernatural ability.
