This chapter aims to find eight testimonies that concern Nazi medical experiments. They are: Frantisek Blaha, Leo Eitinger, Berthold Epstein, Viktor/Vitezslav Horn, Frantsek Janouch, Josef Podlaha, Karl Sperber, and Rudolf Weisskopf/Vitek. The process of dealing with the horrific Nazi legacy both in legal and moral terms, including the misuse of medicine, had many forms, and was often widely different in the various formerly Nazi-occupied countries. Representatives of the Czechoslovak government-in-exile participated in the debates and later in the preparation of investigation and prosecution of Nazi medical crimes from the very outset. Investigation undertaken by the authorities of restored Czechoslovakia focused from the start at gathering, documenting and evaluating accessible sources of information. During the immediate post-war period, investigation was carried out almost exclusively by Czechoslovak intelligence services, which were, however, marked by a split reflecting the different politics of Czechoslovak exile representation in Great Britain on the one hand and the Soviet Union on the other hand.
