GRADUATE DOCTOR of the Faculty of Medicine of Lyon, distinguished
psychical researcher and Director of the Institut Metapsychique
International of 1919 to 1924.
In his first book, l'Etre Subconscient, published in 1899 in Paris, he
expounded a theory of dynamo-psychism, a sort of soul energy by which he
sought to escape from the trammels of materialistic philosophy. In his
second book, From the Unconscious to the Conscious, he developed this
into a more comprehensive treatise and learned to admitting an external
direction and intention in the phenomena of trance which cannot be
referred to the medium or to the experimenters. Shortly before the
publication of this work, which is considered by many as the most
important contribution to psychical research since Prof. Frederic
Myers' Human Personality, he abandoned his medical practice at Anney and
accepted, from Jean Meyer, the post of the director of the Institut
Metapsychique International founded by Mr. Meyer.
Geley was a very keen and indefatigable investigator; when, under
fraud-proof circumstances, supernormal results were produced in his
laboratory he had to defend himself against the accusation of medical
colleagues that he was an accomplice of mediums. He actually consented to
have his premises examined for secret doors and to being chained up with
The most palpable evidence he produced for the reality of mediumstic
phenomena were the Kluski plaster casts, which are still on view in the
Institute. His last book, Clairvoyance and Materialisation, based
chiefly on his experiences with Eva C., marks another milestone in
psychical research. It was to have been followed by a second volume, The
Genesis and Meaning of Metapsychic Phenomena, of which, however, the
world was deprived by his sudden death in an aeroplane accident on July
15, 1924, a few days after a last experiment with Kluski in Warsaw.
Essentially, Geley was a survivalist but he was careful not to declare
himself on subjects which would have alienated scientific opinion.
