In the 1920s and ’30s, were there Yiddish-speaking analysts practicing in Vienna, Berlin, Warsaw, Vilna? What did that world look like?
Everywhere there were psychoanalysts, there were Yiddish-speaking psychoanalysts, though generally Yiddish was not the explicit language of the analysis. It perhaps continued to exert its influence under the surface, as a shared unspoken language between analyst and analysand.
There are many examples, but we can point to two particularly important ones. A. A. Brill was a native Yiddish speaker and Freud’s first English translator. Wilhelm Stekel was among Freud’s first disciples, and Stekel’s first case appears to have been the fifth Lubavitcher Rebbe, who came to Vienna to be treated for a (hysterical) paralysis of the right side. My guess is that Freud assigned Stekel to the case on linguistic grounds, since Stekel had spent his boyhood summers in the Hasidic court town of Boyan. Freud himself, in the only surviving case notes, recorded the Yiddish curses directed at him by the Rat Man (Ernst Lanzer).
Freud’s Yiddish translators were not, however, psychoanalysts, though it would be interesting to know whether collective psychoanalytic research of the sort Weinreich was doing helped shape the translation. I have to think about that.
