Spiritualism and Psychical Research

Séances, mediums, and the scientists who tried to test them.

Modern Spiritualism began in 1848 with the rappings at the Fox sisters’ house in New York and became a mass movement within a decade. Its claim that the dead could communicate prompted serious scientists to investigate, founding the field of psychical research.

This guide pairs the movement’s own histories and teachings with the investigators’ reports.

What It Is

Spiritualism was a religion of demonstration: séances, trance speaking, materialisations. In France, Allan Kardec codified Spiritism as a philosophy of reincarnation and moral progress. Investigators such as William Crookes and Charles Richet brought laboratory methods, with contested results.

Why It Matters

Spiritualism shaped women’s public voices, reform movements, Theosophy and early psychology. Its archive is also an extended case study in evidence, belief and fraud.
