Germans are known for their high standards and attention to detail. From early progress in the link between smoking and cancer, to triumphs in aviation – their scientists have been among the greatest in the world. This four-part series examines the effect Hitler’s Nazi regime had on the scientific progress in the country – from world leaders to crumbled ruins. Science And The Swastika investigates how biology, medicine, physics and aviation fared during the Thousand Year Reich. An uncomfortable truth emerges – while some scientific work was carried out to morally repugnant ends, many German scientists actually did ‘good science’, rigorously conducted in a dispassionate and rational way. This troubling legacy demands that we continue to question our understanding of science and the moral responsibilities of scientists.
