Lou Andreas-Salome (1861-1937) was a writer and disciple of Freud who became a practicing analyst. For over two decades she and Freud kept up an intensive correspondence. Freud found in her a perceptive appreciater and amplifier of his ideas, and Frau Andreas found him a sympathetic critic of her own. Their exchanges on theoretical topics and clinical experiences, their admiring friendship, and the glimpses of their personalities make this collection invaluable for readers interested in the history of psychoanalysis. The book includes an introduction and notes by Ernst Pfeiffer, Lou Andreas-Salome’s literary executor.
