The papers of psychoanalyst Sigmund Freud (1856-1939) span the years from about the 6th century B.C.E. (a small Greek statue) to 1998, with the bulk of material dating from 1871 to 1939. The digitized collection documents Freud's founding of psychoanalysis, the maturation of psychoanalytic theory, the refinement of its clinical technique, and the proliferation of its adherents and critics. Many facets of Freud's life and work are reflected, including his early medical and clinical training; his relationship with family, friends, colleagues, students, and patients; his association with early psychoanalytic societies; his perspectives on analytical training; and his numerous writings.
