The Society for Psychical Research’s Investigation of Eusapia Palladino

Record summary

Eusapia Palladino was an Italian medium whose séances attracted investigators including members of the Society for Psychical Research and prominent scientists. The lead is valuable for comparing controlled observation, séance etiquette, fraud allegations, experimental design, and the interpretive pressures surrounding a celebrated medium. Some investigators reported unusual phenomena, while others documented opportunities for limb movement, substitution, or deception; later assessments remain divided over particular sittings. The case is well documented in psychical-research literature but does not establish that the reported effects were paranormal.
