Bowlby was primarily a theorist rather than a therapist. Although trained psychoanalytically, and active in the Psychoanalytical Society from the late 1930s until the late 1950s, he saw himself mainly as a researcher and administrator. Case reports and clinical illustrations are to be found throughout his writings, but, with the exception of his earliest papers, these are almost all based on the work of colleagues or on published articles by other authors. Dreams are nowhere to be found in his work, and he is, for the most part, concerned with observable behaviour rather than the inner world. Nevertheless, Attachment Theory is a child of psychoanalysis and has much to contribute to the theory and practice of the various modalities of psychotherapy, incuding psychoanalysis.
