Charles Samson Féré (13 July 1852 in Auffay - 22 April 1907) was a French physician.
He initially studied medicine in Rouen, where he subsequently served at the Hôtel-Dieu under surgeon Achille Flaubert (1813-1882), an older brother of writer Gustave Flaubert (1821-1880). Afterwards, he relocated to Paris, where in 1877 he gained his internship. In 1881 he began work as an assistant to Jean-Martin Charcot (1825-1893), who was a profound influence to Féré's career. In 1887, he was appointed chief medical officer at the Hospice Bicêtre, remaining there for the rest of his career.
Féré's wide-ranging research covered subjects such as medicine, psychology, criminology, sexuality, hypnosis, Darwinism, heredity, et al. The following are a few of his principal written works:
Féré is credited with introducing the term "hallucination altruiste" to denote a hallucination depicting a person to whom a sensation, wish, or feeling is conveyed or attributed.[3]
