[René Allendy, or the evolution of a misunderstanding]

The publication of the correspondence between Sigmund Freud and René Laforgue clarifies the conditions of the development of psychoanalysis in France. Freud's cautiousness towards French psychoanalysts is immediately apparent. It rests on what Freud perceives as a lack of respect for the founding principles of his work. The misunderstanding between Vienna and Paris is immediate, profound and enduring. The evolution of this misunderstanding, its transmission, and its effects, will be depicted by studying the work and the practice of René Allendy.
