Biography
For his MD at the Institute for Sexual Research at the University Hospital Eppendorf in Hamburg in 1976 he laid the first international empirical survey of sadomasochists and their subculture. Years later his studies were published in book form which to date have been translated into several language. One of the most important aspects of this study consisted in its being the first to approach in an empirical way and with modern sociological techniques the subject of sadomasochism, and oppose their results to the assumptions and conclusions of the only previous study done by Krafft-Ebing. In Hamburg he later became involved in social-psychiatric reform projects and the development of psychiatric emergency service.

From 1988 to 2008 he served as medical director at the Lower Saxony State Hospital Wunstorf, today Klinikum Region Hannover Wunstorf. He is a full member of the International Academy of Sex Research and a member of other professional societies, and has published about sexology, psychiatric emergencies, involuntary commitment, forensic psychiatry, and mental health service. He is a qualified medical specialist in psychiatry, psychotherapy and forensic psychiatry. From 2008 to spring 2013 he has served as chairman of the Lower Saxony Committee on matters of mental health care. Beside his main profession, he is get involved with outsider art and history.
