Gustav Geley

Gustav Geley (13 April 1868 – 15 July 1924) was a French physician, psychical researcher and director of the Institute Metapsychique International from 1919 to 1924.

[2] In the early 20th century Joaquin María Argamasilla known as the "Spaniard with X-ray Eyes" claimed to be able to read handwriting or numbers on dice through closed metal boxes.

[5] It was reported in the Encyclopedia of Occultism and Parapsychology that Geley's "belief system seems to have made him a target for tricks by the mediums he studied and, in the end, capable of suppressing negative evidence.

[6] Lambert who had studied Geley's files on Eva Carrière discovered photographs depicting fraudulent ectoplasm taken by her companion Juliette Bisson.

Eugene Osty (the director of the institute) and members Jean Meyer, Albert von Schrenck-Notzing and Charles Richet all knew about the fraudulent photographs but were firm believers in mediumship phenomena so demanded the scandal be kept secret.
