Operation Epsilon

From July to December in 1945, ten German scientists, Bagge, Diebner, Gerlach, Hahn, Harteck, Heisenberg, Korsching, von Laue, von Weizsacker, and Wirtz, were held and clandestinely recorded by the British. The scientists discuss their progress and react to the bombing of Hiroshima.

In the spring of 1945 the Allies arrested the physicists they believed had worked on the German nuclear programme. Interned in an English country house owned by MI6, their conversations were secretly recorded. Operation Epsilon sought to determine how close Nazi Germany had come to building an atomic bomb. It was in this quiet setting – Farm Hall, near Cambridge – that the interned physicists first heard of the attack on Hiroshima. Aside from changing the course of history, that night was also one of great shock and personal defeat for the physicists – they were under the assumption that they alone had discovered nuclear fission. This is the story of Nazi Germany’s hunt for a nuclear bomb. It is a tale of the genius and guilt of lauded, respected scientists.

In this book, Mark Walker - a historical scholar of Nazi science - brings to light the overwhelming impact of Hitler's regime on science and, ultimately, on the pursuit of the German atomic bomb. Walker meticulously draws on hundreds of original documents to examine the role of German scientists in the rise and fall of the Third Reich. He investigates whether most German scientists during Hitler's regime enthusiastically embraced the tenets of National Socialism or cooperated in a Faustian pact for financial support, which contributed to National Socialism's running rampant and culminated in the rape of Europe and the genocide of millions of Jews. This work unravels the myths and controversies surrounding Hitler's atomic bomb project. It provides a look at what surprisingly turned out to be an Achilles' heel for Hitler - the misuse of science and scientists in the service of the Third Reich.

This book provides a rounded biography of Franz (later Sir Francis) Simon, his early life in Germany, his move to Oxford in 1933, and his experimental contributions to low temperature physics approximating absolute zero. After 1939 he switched his research to nuclear physics, and is credited with solving the problem of uranium isotope separation by gaseous diffusion for the British nuclear programme Tube Alloys. The volume is distinctive for its inclusion of source materials not available to previous researchers, such as Simon's diary and his correspondence with his wife, and for a fresh, well-informed insider voice on the five-power nuclear rivalry of the war years. The work also draws on a relatively mature nuclear literature to attempt a comparison and evaluation of the five nuclear rivals in wider political and military context, and to identify the factors, or groups of factors, that can explain the results.

From April through December of 1945, ten of Nazi Germany's greatest nuclear physicists were detained by Allied military and intelligence services in a kind of gilded cage at Farm Hall, an English country manor near Cambridge. The physicists knew the Reich had failed to develop an atomic bomb, and they soon learned, from a BBC radio report on August 6, that the Allies had succeeded in their own efforts to create such a weapon. But what they did not know was that many of their meetings and private conversations were being monitored and recorded by British agents. This book contains the complete collection of transcripts that were made from these secret recordings, providing an unprecedented view of how the German scientists, including two Nobel Laureates, thought and spoke about their roles during the war.

"Exhaustively detailed yet eminently readable, this is an important book."Publishers Weekly, starred review "Cassidy does not so much exculpate Heisenberg as explain him, with a transparency that makes this biography a pleasure to read."Los Angeles Times "Well crafted and readable . . . [Cassidy] provides a nuanced and compelling account of Heisenberg's life."The Harvard Book Review In 1992, David C. Cassidy’s groundbreaking biography of Werner Heisenberg, Uncertainty, was published to resounding acclaim from scholars and critics. Michael Frayn, in the Playbill of the Broadway production of Copenhagen, referred to it as one of his main sources and “the standard work in English.” Richard Rhodes (The Making of the Atom Bomb) called it “the definitive biography of a great and tragic physicist,” and the Los Angeles Times praised it as “an important book. Cassidy has sifted the record and brilliantly detailed Heisenberg’s actions.” No book that has appeared since has rivaled Uncertainty, now out of print, for its depth and rich detail of the life, times, and science of this brilliant and controversial figure of twentieth-century physics. Since the fall of the Soviet Union, long-suppressed information has emerged on Heisenberg’s role in the Nazi atomic bomb project. In Beyond Uncertainty, Cassidy interprets this and other previously unknown material within the context of his vast research and tackles the vexing questions of a scientist’s personal responsibility and guilt when serving an abhorrent military regime. David C. Cassidy is the author of J. Robert Oppenheimer and the American Century, Einstein and Our World, and Uncertainty.

Lise Meitner (1878-1968) was a pioneer of nuclear physics and co-discoverer, with Otto Hahn and Fritz Strassmann, of nuclear fission. Braving the sexism of the scientific world, she joined the prestigious Kaiser Wilhelm Institute for Chemistry and became a prominent member of the international physics community. Of Jewish origin, Meitner fled Nazi Germany for Stockholm in 1938 and later moved to Cambridge, England. Her career was shattered when she fled Germany, and her scientific reputation was damaged when Hahn took full credit—and the 1944 Nobel Prize—for the work they had done together on nuclear fission. Ruth Sime's absorbing book is the definitive biography of Lise Meitner, the story of a brilliant woman whose extraordinary life illustrates not only the dramatic scientific progress but also the injustice and destruction that have marked the twentieth century.
