After World War II, most scientists in Germany maintained that they had been apolitical or actively resisted Nazi regime, but true story is much more complicated. In Serving Reich, Philip Ball takes a fresh look at that controversial history, contrasting career of Peter Debye, director of Kaiser Wilhelm Institute for Physics in Berlin, with those of two other leading physicists in Germany during Third Reich: Max Planck, elder statesman of physics after whom Germany's premier scientific society is now named, and Werner Heisenberg, who succeeded Debye as director of institute when it became focused on development of nuclear power and weapons. Mixing history, science, and biography, Ball's gripping exploration of lives of scientists under Nazism offers a powerful portrait of moral choice and personal responsibility, as scientists navigated the grey zone between complicity and resistance. Ball's account of different choices these three men and their colleagues made shows how there can be no clear-cut answers or judgement of their conduct. Yet, despite these ambiguities, Ball makes it undeniable that German scientific establishment as a whole mounted no serious resistance to Nazis, and in many ways acted as a willing instrument of state. Serving Reich considers what this problematic history can tell us about relationship of science and today. Ultimately, Ball argues, a determination to present science as an abstract inquiry into nature that is above politics can leave science and scientists dangerously compromised and vulnerable to political manipulation.
