I have now completed the sketch of some of the foul crimes which these defendants committed in the name of research. The horrible record of their degradation needs no underlining. But German medical science was in past years honored throughout the world, and many of the most illustrious names in medical research are German. How did these things come to pass? I will outline briefly the historical evidence which we will offer and which, I believe, will show that these crimes were the logical and inevitable outcome of the prostitution of German medicine under the Nazis. GERMAN MEDICAL ORGANIZATION Before 1933 Two years after the reconstitution of the German Reich, in 1871, the German Medical Association (Deutscher Aerztevereinsbund) was created, which tied together the older local medical associations. This society existed until it was abolished by the Nazi Government. Its structure was democratic, and its interests included problems of hygiene and public health, and to an increasing extent, socio-medical problems especially in the field of sickness and disability insurance. Bismarck’s legislation of 1881 established compulsory sickness insurance for workmen. In the course of the ensuing years, the vast bulk of the workmen were insured, and consequently most of the ordinary physician’s patients came to be insured patients. There were lists of physicians authorized to treat insured patients, and it was a matter of vital moment to every practicing physician to be listed. To protect their interest with respect to listing, fees, and other such problems, the German doctors founded a voluntary association for the defense of their economic interests known as the Hartmann Bund. Questions of professional ethics, medical malpractice, etc., were handled in Germany in two distinct sets of medical boards or “Courts.” An entirely unofficial and voluntary system was established by the German Medical Association. The other, which was endowed with semi-official status, was called the Reich Chamber of Physicians. These chambers were elected by vote of the members and were supported by an assessment. In addition to these organizations, there existed in Germany purely professional societies of doctors, where papers concerning scientific and practical problems were read and discussed, and which established connections with similar societies abroad. The German Government agencies which supervised the certification and licensing of physicians as well as their professional activities were the Ministry of Education and the Reich Health Office (Reichsgesundheitsamt) in the Ministry of the Interior. The latter supervised medical practice and licensing through the channels of the Ministries of the Interior of the various German states, although licensing was a federal function rather than a state function.
