The Menninger Clinic is an international facility for mental health treatment education, research, and prevention. It was started in 1925 by Dr. Charles Frederick, Karl A. Menninger and his two sons, Karl and Will. In the 1930s, a small group of highly dedicated clinicians began to develop methods of applying psychoanalytic ideas to hospital treatment. Their approach to treating the mentally ill reflected a concern for the total environment of the patient. By 1942 the Topeka Institute for Psychoanalysis was founded as part of the Menninger Clinic. The center became a major training site for American psychiatry. As the center developed, research became a priority. The Menninger Psychotherapy Research Project was a seminal investigation of psychoanalysis and psychoanalytic psychotherapy.
The Topeka Institute for Psychoanalysis training programs and psychoanalytically oriented research programs on the psychotherapy process and outcomes on child development are significant contributions to psychoanalysis.
The Menninger Foundation has since relocated to Houston in partnership with Baylor College of Medicine.
