Without exaggerating the importance of my own person, a physician can only be measured according to his conception of medical science. Basically, I was neither a cold technical specialist nor a pure scientist. I believe that I have always tried, for example when carrying out surgical experiments, to see every disease as a human condition of suffering. I did not look on my task as something to serve my own advantage, or as a cheap gesture of theoretical pity, but as a personal active support to the trembling existence of the suffering patient. My goal as a physician was not so much purely technical therapy for the individual patient, as therapeutical care for the particularly underprivileged group of the poor, the children, the cripples, the neurotics. I am anxious that it should be believed that it was not due to moral baseness nor to the selfish arrogance of the scientist that I came into contact with experiments on human beings. On the contrary, during the entire period in question I had experiments in my field of research carried out on animals. It was only because I was the competent responsible surgical expert that I was informed about the imminent experiments on human beings in my field of surgery, which had been ordered by the state authorities. After the order had been given, it was no longer a question of stopping these experiments, but the problem was the method of their execution. My problems as an expert consisted of the following: For one, the experiments that had been ordered had to be of practical scientific value, for the purpose of testing immunization to protect thousands of injured and sick. On the other hand, I considered humane safety measures for the experimental subjects most important. The main point for me was never the purpose and the object of the experiments, but the manner in which they were carried out. To realize that in a humane way I did not remain aloof and restrict myself to theoretical instruction in the field of surgery, but I myself took part, with my clinic and with all its safety measures. I hope that this will show that in carrying out experiments I tried with the best of intentions to act primarily in the interest of the experimental subjects. We did not take advantage of the unlimited opportunities given us by Himmler, that is to say, the surgical experiments were not followed by others. I believe that as far as was possible at that chaotic period I fulfilled my duty as an expert, because these experiments did not increase in the field of surgery in spite of the crescendo of the catastrophic policy. My desire was to help and not to give a bad example. In seeing my responsibility in this way I, of course, made a decision for myself. I hope that hitherto I have always faced criticism, even from foreign countries, without any secrecy, but also without any feeling of guilt for my activities as an expert.
