In a rich and fascinating history John Cornwell tells the epic story of Germany's scientists from the First World War to the collapse of Hitler's Reich. He shows how Germany became the world's Mecca for inventive genius, taking the lion's share of Nobel awards, before Hitler's regime hijacked science for wars of conquest and genocidal racism. Cornwell gives a dramatic account of the wide ranging Nazi research projects, from rockets to nuclear weapons; the pursuit of advanced technology for irrational ends, concluding with with penetrating relevance for today: the inherent dangers of science without conscience.
