Praise for Hiroshima ‘An engaging and exceptionally skillful combination of the scientific, tech- nological, military, diplomatic, political, and cultural history of the atomic bomb in an international context. By any standard, a terrific book.’ J. Samuel Walker, author of Prompt and Utter Destruction: Truman and the Use of Atomic Bombs against Japan ‘In a smart, useful, and beautifully written book, Rotter treats the atomic bombing of Japan in its multinational context. Synthesizing a huge liter- ature, he concisely shows in how many ways this truly was the world’s bomb.’ Laura Hein, Northwestern University, and author of Living with the Bomb ‘A profound look at one of mankind’s most significant (and tragic) events...diplomats and their politician bosses should read this work for an understanding of the dire outcomes that diplomacy—and a lack thereof— can reap.’ Thomas W. Zeiler, University of Colorado, and author of Unconditional Defeat: Japan, America, and the End of World War II Acknowledgements I never intended to write a book on the atomic bomb, but when David Reynolds emailed out of the blue, as it were, in the summer of 2001 and asked me to write one for a new Oxford series, I could not resist his invitation. I have appreciated his support and advice throughout the protracted writing process. Katherine Reeve was my first editor and got me started; Luciana O’Flaherty took over and prodded me to finish during my sabbatical leave in London in 2006. Luciana’s able and helpful assistant, Matthew Cotton, and my Oxford production editor Kate Hind, brought the book home. Hilary Walford copyedited the manuscript, even as the water rose around her house in Gloucester during the summer of 2007. Zoe Spilberg hunted down the photographs and negotiated permission for their use. Carolyn McAndrew handled the proofreading and eliminated the last of my sincere but, as it turned out, unnecessary attempts to spell in British. I got interested in the atomic bomb because of my Stanford University graduate adviser Barton J. Bernstein, whose deep research on the subject I only gloss here. At Colgate University, my home institution, I was lucky enough to teach a course on the bomb with my colleague from across the Quad, Charles Holbrow. Since Charlie was responsible for doing the physics part of the course, I was fortunate that Robin Marshall, a physicist at the University of Manchester, read the manuscript and saved me from a number of errors. Laura Hein offered suggestions throughout, and Sam Walker bravely read the entire manuscript and said nice things about the writing. Conversations with friends and colleagues, including Carl Guarneri, David Robinson, Karen Harpp, Walter LaFeber, Frank Costigliola, and Jeremi Suri, helped to keep me on task, more or less. I am grateful to them all. I also thank audiences at the University of Minnesota, the University of Wisconsin, Fitchburg State College, Nanzan University, Kitakyushu University, and the Hiroshima Peace Institute, for questions, viii Acknowledgements comments, and corrections following my lectures at these places. Students and colleagues at Colgate helped enormously. Thanks especially to my four terrific research assistants: Sarah Hillick, Alexander Whitehurst, Adam Florek, and Casey Graziani. My parents, Roy and Muriel Rotter, and my in-laws, Chandran and Lorraine Kaimal, supported me unswervingly, which they seem to think is their job. My daughters, to whom the book is dedicated, have become young women in the course of my writing it. In the acknowledgements in my last book I characterized them as “naughty”; they are that no longer, but smart and beautiful and my proudest work ever. As always, my greatest debt is to my wife, Padma. Writing about the atomic bomb is not the most cheerful of pursuits. She kept me going, and much more.

From a clear blue sky on a radiantly hot summer morning came a single American B-29 bomber (warily flanked by two observation planes), carrying a single bomb. The plane was called the Enola Gay, after its pilot’s mother; the bomb bore the innocent nickname ‘Little Boy’. There were no Japanese fighter planes to challenge the Enola Gay, no airbursts of flak in its way.
