Joseph Grasset

Joseph Grasset (18 March 1849 – 7 July 1918), was a French neurologist and parapsychological investigator, born in Montpellier.

[1] Grasset was involved in every aspect of internal medicine, but his primary interest concerned diseases of the nervous system.

[1] He conducted studies in the field of psychiatry, publishing the book Demi-fous et Demi-responsables (Semi-Insane and the Semi-Responsible) in 1907, and also researched the paranormal, publishing works with titles such as Le spiritisme devant la science (1904) and L’occultisme hier et aujourd'hui (1907).

Grasset took a psychological approach to psychical research and attributed mediumship to deliberate trickery or unconscious suggestion.
