Works together with Josef Breuer on "Studies in Hysteria".
Joseph and Mathilde Breuer
Josef Breuer with his wife Mathilde, after whom Freud named his eldest daughter.
In 1893 the two men publish "On the Psychical Mechanism of Hysterical Phenomena: A Preliminary Communication". Two years later this is followed by the jointly written "Studies in Hysteria".
Freud considers hysteria to be the consequence of traumas caused by sexual abuse in childhood. Differences of opinion on the sexual aetiology of hysteria afterwards lead to a cooling of the friendship with Breuer.
