This chapter explores the transition of editorial control over the Swiss journal Jahrbuch from Switzerland to Vienna in an analysis of the last issue that Jung edited under the shadow of his official resignation and the first issue that Freud edited in his stead. If Jung, Eugen Bleuler, and Freud launched the Jahrbuch with the publication of Freud’s “Little Hans,” which contained the psychoanalytic solution to the riddle of antisemitism in a startling digression, for the purpose of announcing the successful partnership between the Jewish members of the Vienna Psychoanalytic Society and the Protestant members associated with the Burghölzi Hospital, I argue that Jung’s publication of Alphonse Maeder’s “Dream of the Blue Horse” sought to repudiate Freud’s debut article. Whereas Freud had theorized that the roots of antisemitism lay in concerns over the circumcised Jewish penis in the non-Jewish psyche, the “Dream of the Blue Horse” theorized that the notion of intrapsychic antisemitism was a paranoid constellation wrought by oversexualized Jewish minds.
