[Creation of Charcot's chair].

A decree signed by the President of the French Republic on the 2nd of January 1882 provided for the creation of the first chair in the world for the teaching of neurology at the Faculty of medicine in Paris. The chair was named: Clinic for Diseases of the Nervous System and was attributed to J. M. Charcot. The historical and political circumstances related to the creation of this chair are reviewed. J. M. Charcot's hospital and university careers are retraced, emphasis being placed on the turning point in 1867 when J. M. Charcot, having been refused the chair of Medical Pathology, dedicated his time to the study of hysteria and nervous system diseases. The birth of neurology is therefore situated in relation to that of psychiatry. But this chair is also and still that of Charcot; it was thus convenient to remind the man, his origins, his personality, his ideas, and his social role.
