One of the pioneers in psychosomatic medicine was Helen Flanders Dunbar (1902-1959) who has studied medicine, philosophy, and theology and who has had great impact on organizing the psychosomatic approach in America. In her scientific busy life she served as a teacher for medical and chaplain students, performed a lot of research, maintained a private psychoanalytic praxis, and published not only many journal articles, but also nine scientific books. Nowadays she is mostly unknown in the German scientific field. This book aims to adjust that view and to show her impact on the psychosomatics of the 21 century. Herr nickname "mother" of psychosomatic medicine is well earned.
