Heinrich Kremer, MD, Medical Director Emeritus was, from 1968-1975, head of social therapy for addicts, sexual offenders and people with personality disorders at the Berlin Tegel prison which was the pilot project for the reform of the German penal system. In 1988 he resigned as medical director of a model clinic specializing in youth drug addiction due to differences on medical ethics regarding the HIV test and AIDS therapy. From 1993-1999 as collaborating member of the Study Group for Nutrition and Immunity (Bern) he investigated together with Prof. Alfred Hässig the mechanisms occurring in AIDS defining illnesses and in cancer. Since the publication of this book in German in 2001 he has been in demand as a lecturer on the treatment of chronic diseases, working today as senior consultant in a growing medical network for Cell Symbiosis Therapy®.
