This paper traces some aspects of the fertile matrix within which, over many years, the application of a psychoanalytic perspective to clinical work with the most severely mentally ill, difficult and at times frightening patients in secure and community settings has evolved and now led to the recent inauguration of the Forensic Psychotherapy Society (FPS), a new Member Institution of the British Psychoanalytic Council. The Society provides both a framework for a national, multidisciplinary professional training in psychodynamic forensic psychotherapy and the potential launching pad for an active post-qualification organisation supporting CPD and all other forms of professional development. The particular contributions to the birth of the FPS of the Forensic Psychotherapy Department at West London Mental Health NHS Trust, partly because we know it best but also because it is part of the largest forensic psychiatric service in the United Kingdom, are described.
