physicians, but other cultured men who had recognized something significant in psychoanalysis. There were authors, artists, and so forth. The “Interpretation of Dreams,” the book on “Wit,” and other writings, had already shown that the principles of psychoanalysis cannot remain limited to the medical field, but are capable of application to various other mental sciences. In 1907 the situation suddenly altered and quite contrary to all expectations; it became evident that psychoanalysis had unobtrusively awakened some interest and gained some friends, that there were even some scientific workers who were prepared to admit their allegiance. A communication from Bleuler had already acquainted me with the fact that my works were studied and applied in Burghölzli.[4] In January, 1907, the first man attached to the Zürich Clinic, Dr. Eitingon, visited me at Vienna. Other visitors soon followed, thus causing a lively exchange of ideas. Finally, by invitation of C. G. Jung, then still an assistant physician at Burghölzli, the first meeting took place at Salzburg, in the spring of 1908, where the friends of psychoanalysis from Vienna, Zürich, and other places met together. The result of this first psychoanalytic congress, was the founding of a periodical, which began to appear in 1909, under the name of “Jahrbuch für Psychoanalytische und Psychopathologische Forschungen,” published by Bleuler and Freud, and edited by Jung. An intimate comradeship in the work done at Vienna and Zürich found its expression in this publication.
