One of the last secrets of World War II is why the Germans failed to build an atomic bomb. Germany was the birthplace of modern physics; it possessed the raw materials and the industrial base; and it commanded key intellectual resources. What happened? In Heisenberg's War, Thomas Powers tells of the interplay between science and espionage, morality and military necessity, and paranoia and cool logic that marked the German bomb program and the Allied response to it. On the basis of dozens of interviews and years of intensive research, Powers concludes that Werner Heisenberg, who was the leading figure in the German atomic effort, consciously obstructed the development of the bomb and in a famous 1941 meeting in Copenhagen with his former mentor Neils Bohr in effect sought to dissuade the Allies from their pursuit of the bomb. Heisenberg's War is a "superbly researched and well-written book" (Time) whose extraordinary story engrosses—and haunts.

A close-up look at Nazi attempts to build an atomic bomb describes the German bomb program, the Allied response to it, and the roles of some of the twentieth century's leading physicists

The story of the interplay between science and espionage, morality and military necessity, which marked the German bomb programme and the Allied response to it. It revolves round Werner Heisenberg, one of the century's greatest physicists and the only one of real stature to stay on during the war.

In this "superbly researched and well-written book" (Time), Powers concludes that Werner Heisenberg, the leading figure in the German atomic effort, consciously obstructed the development of the bomb and in a famous 1941 meeting in Copenhagen sought to dissuade the Allies from their pursuit of the bomb.

No one better represents the plight and the conduct of German intellectuals under Hitler than Werner Heisenberg, whose task it was to build an atomic bomb for Nazi Germany. The controversy surrounding Heisenberg still rages, because of the nature of his work and the regime for which it was undertaken. What precisely did Heisenberg know about the physics of the atomic bomb? How deep was his loyalty to the German government during the Third Reich? Assuming that he had been able to build a bomb, would he have been willing? These questions, the moral and the scientific, are answered by Paul Lawrence Rose with greater accuracy and breadth of documentation than any other historian has yet achieved. Digging deep into the archival record among formerly secret technical reports, Rose establishes that Heisenberg never overcame certain misconceptions about nuclear fission, and as a result the German leaders never pushed for atomic weapons. In fact, Heisenberg never had to face the moral problem of whether he should design a bomb for the Nazi regime. Only when he and his colleagues were interned in England and heard about Hiroshima did Heisenberg realize that his calculations were wrong. He began at once to construct an image of himself as a "pure" scientist who could have built a bomb but chose to work on reactor design instead. This was fiction, as Rose demonstrates: in reality, Heisenberg blindly supported and justified the cause of German victory. The question of why he did, and why he misrepresented himself afterwards, is answered through Rose's subtle analysis of German mentality and the scientists' problems of delusion and self-delusion. This fascinating study is a profound effort to understand one of the twentieth century's great enigmas.

An explosive re-imagining of the mysterious wartime meeting between two Nobel laureates to discuss the atomic bomb.

Personal letters reveal the quandary of a prominent German physicist during the Nazi years and the strength he shared with his loving wife Nobel Prize–winning physicist Werner Heisenberg lived far from his wife, Elisabeth, during most of the Second World War. An eminent scientist, Werner headed Germany’s national atomic research project in Berlin, while Elisabeth and their children lived more safely in Bavaria. This selection of more than 300 letters exchanged between husband and wife reveals the precarious nature of Werner’s position in the Third Reich, Elisabeth’s increasingly difficult everyday life as the war progressed, and the devoted relationship that gave strength to them both. These letters provide a fascinating new perspective on Werner’s much-debated wartime work and his attitude toward the atomic bomb. They also shed light on his reluctance to emigrate despite the urging of friends. An excerpt from his private diary, an introduction and notes by his daughter, and a selection of personal family photographs complete this compelling volume.
