Introduction
Despite knowledge since the postwar period and the efforts of neurologist Leo Alexander, the neuroscience community has been slow to recognize its involvement in the racial hygiene policies of the Third Reich. Part of this has been denial, but part of it protective of past perpetrators. However, since the popularization of medicine in the Nazi era in the 1980s, the fall of the Berlin Wall making previously unavailable patient data in the 1990s, and some astute articles in the neurology literature, neuroscience in the Nazi era has emerged as a scientific topic. Pioneering works by Shevell and Peiffer highlighted the unethical involvement of even famed German neuroscientists such as Julius Hallervorden. In the 2000s a growing body of literature has begun to show common threads between the exile of persecuted neuroscientists and the rise of increasingly destructive policies toward neurologic patients, and the exploitation of these patients for scientific research.
