In October 1885, Freud went to Paris on a three-month fellowship to study with Jean-Martin Charcot, a renowned neurologist who was conducting scientific research into hypnosis. He was later to recall the experience of this stay as catalytic in turning him toward the practice of medical psychopathology and away from a less financially promising career in neurology research. Charcot specialized in the study of hysteria and susceptibility to hypnosis, which he frequently demonstrated with patients on stage in front of an audience.
