"The Nazi medical experiments and even the program for the destruction of “lives not worth living” represent only the tip of a much larger iceberg. In fact, the ideological structure we associate with National Socialism was deeply embedded in the philosophy and institutional structure of German biomedical science long before the beginning of the euthanasia program in 1939-and to a certain extent, even before 1933. The published record of the German medical profession makes it clear that many intellectuals cooperated fully in Nazi racial programs, and that many of the social and intellectual foundations for these programs were laid long before the rise of Hitler to power. What I want to argue in addition to this, however (and here I shall be drawing upon a growing body of recent German scholarship on this question) is that biomedical scientists played an active, even leading role in the initiation, administration, and execution of Nazi racial programs. In this sense the case can be made that science (especially biomedical science) under the Nazis cannot simply be seen in terms of a fundamentally “passive” or “apolitical” scientific community responding to purely external political forces; on the contrary, there is strong evidence that scientists actively designed and administered central aspects of National Socialist racial policy."
