interested in hearing of the case of Anna O, which ... made a deep impression on him"; and in his 1909 Five Lectures on Psycho-Analysis, Freud generously pointed out, "I was a student and working for my final examinations at the time when ... Breuer, first (in 1880-2) made use of this procedure ... Never before had anyone removed a hysterical symptom by such a method." Freud and Breuer documented their discussions of Anna O. and other case studies in their 1895 book, Studies in Hysteria. These discussions of Breuer's treatment of Anna O. became "a formative basis of psychoanalytic practice, especially the importance of fantasies (in extreme cases, hallucinations), hysteria [...], and the concept and method of catharsis which were Breuer's major contributions." Louis Breger has observed that in the Studies, "Freud is looking for a grand theory that will make him famous and, because of this, he is always fastening on what he thinks will be a single cause of hysteria, such as sexual conflict...Breuer, on the other hand, writes about the many factors that produce symptoms, including traumas of a variety of kinds. He also gives others, such as Pierre Janet, credit and argues for “eclecticism”; he is open to many different ways of understanding and treating hysteria." The two men became increasingly estranged. From a Freudian standpoint, "while Breuer, with his intelligent and amorous patient Anna O., had unwittingly laid the groundwork for psychoanalysis, it was Freud who drew the consequences from Breuer's case." However, Breger notes that Breuer, while he valued Freud's contributions, didn't agree that sexual issues were the only cause of neurotic symptoms; he wrote in a 1907 letter to a colleague that “Freud is a man given to absolute and exclusive formulations: this is a psychical need which, in my opinion, leads to excessive generalization.” Freud later turned on Breuer, no longer giving him credit and helping spread a rumour that Breuer had not been able to handle erotic attention from Anna O. and had abandoned her case, though research indicates this never happened and Breuer remained involved with her case for several years while she remained unwell. In 1894 Breuer was elected a Corresponding Member of the Vienna Academy of Sciences. Family Breuer married Mathilde Altmann in 1868, and they had five children. His daughter Dora later committed suicide rather than be deported by the Nazis. Another one of his daughters,
