Franek Kluski, real name Teofil Modrzejewski (1873-1943), was a Polish physical medium criticized by trained magicians and skeptics as a fraud.
Physician Antônio da Silva Mello noted that Geley "published many writings on ectoplasms and teleplastic phenomena, things which today are quite out of date and totally discredited.
[6] The magician Carlos María de Heredia revealed how fake materialization hands could be made by using a rubber glove, paraffin and a jar of cold water.
In response, Harry Houdini demonstrated that a glove was not needed as he replicated the Kluski materialization moulds by using his hands and a bowl of hot paraffin.
"[9] Researchers have compared Kluski's mediumship to the medium Eva Carrière and have speculated that he introduced items in the séance room by fraud.
[11] Massimo Polidoro and Luigi Garlaschelli have produced wax-moulds directly from one's hand which were exactly the same copies as Geley obtained from Kluski, which are kept at the Institute Metapsychique International.
