mid-1880s as a docent of Vienna University, he had been delivering to small audiences every Saturday evening at the lecture hall of the university's psychiatric clinic. From the autumn of 1902, a number of Viennese physicians who had expressed interest in Freud's work were invited to meet at his apartment every Wednesday afternoon to discuss issues relating to psychology and neuropathology. This group was called the Wednesday Psychological Society (Psychologische Mittwochs-Gesellschaft) and it marked the beginnings of the worldwide psychoanalytic movement. Freud founded this discussion group at the suggestion of the physician Wilhelm Stekel. Stekel had studied medicine at the University of Vienna under Richard von Krafft-Ebing. His conversion to psychoanalysis is variously attributed to his successful treatment by Freud for a sexual problem or as a result of his reading The Interpretation of Dreams, to which he subsequently gave a positive review in the Viennese daily newspaper Neues Wiener Tagblatt. The other three original members whom Freud invited to attend, Alfred Adler, Max Kahane, and Rudolf Reitler, were also physicians and all five were Jewish by birth. Both Kahane and Reitler were childhood friends of Freud. Kahane had attended the same secondary school and both he and Reitler went to university with Freud. They had kept abreast of Freud's developing ideas through their attendance at his Saturday evening lectures. In 1901, Kahane, who first introduced Stekel to Freud's work, had opened an out-patient psychotherapy institute of which he was the director in Bauernmarkt, in Vienna. In the same year, his medical textbook, Outline of Internal Medicine for Students and Practicing Physicians, was published. In it, he provided an outline of Freud's psychoanalytic method. Kahane broke with Freud and left the Wednesday Psychological Society in 1907 for unknown reasons and in 1923 committed suicide. Reitler was the director of an establishment providing thermal cures in Dorotheergasse which had been founded in 1901. He died prematurely in 1917. Adler, regarded as the most formidable intellect among the early Freud circle, was a socialist who in 1898 had written a health manual for the tailoring trade. He was particularly interested in the potential social impact of psychiatry. Max Graf, a Viennese musicologist and father of "Little Hans", who had first encountered Freud in 1900 and joined the Wednesday group soon after its initial inception, described the ritual and atmosphere of the early meetings of the society: The gatherings followed a definite ritual.
