Emma Eckstein's circumcision trauma has been powerfully suppressed, denied, and dissociated from the history of the origins of psychoanalysis. Even though Freud did not categorize it as a trauma, he was deeply impacted by it in the period when he provided psychoanalysis with his foundation. Despite Freud's intellectual erasure of the trauma that Emma experienced, her “cut” never ceased to unconsciously break through Freud's fantasies and discourse, haunting the psychoanalytic building as a veritable ghost. Sándor Ferenczi became the recipient of what Freud could not consider in his own mind, and his revision of the “Bausteine” (building blocks) of psychoanalysis featured an attempt to heal the split embedded in the foundation of psychoanalysis.
