Charcot, Jean Martin (1825-1893) - French physician and early psychotherapist whose use of hypnosis to reach the depth of his patients' problems led him to the conclusion that all neurosis had sexual roots. However, he bowed to his Victorian ethos and never made this conclusion public. One of his students, Sigmund Freud, as well as adopting his teacher's methods and conclusions, did have the courage of his convictions and made his beliefs public. Freud was, however, sufficiently impressed by Charcot to name one of his children after him.
