 Puységur, however, always portrayed himself as a faithful disciple of Mesmer, and never took credit for having invented the procedure that is now known as hypnotic induction.His contributions were gradually forgotten, until Nobel prize-winner Charles Richet rediscovered his writings in 1884, and showed that most of what other people had claimed as their discoveries in the field of magnetism and hypnotherapy were originally due to the Marquis de Puységur.Henri Ellenberger, the great historian of psychoanalysis and psychotherapy, wrote that Puységur was "one of the great forgotten contributors to the history of the psychological sciences."
