"For anyone with an interest in the Manhattan project and the course and conduct of World War II this book is a must-read and a valuable addition to the body of work available on this topic. Frank Settle not only details the herculean task faced by those working on the Manhattan project but also shows the deft touch of General George C. Marshall, FDR's Chief of Staff, and how, in his own inimitable way, he helped steer the project to ultimate fruition."

"Frank Settle's meticulous, well-researched, and thoughtful study of George C. Marshall and the Atomic Bomb is a vital work for anybody seeking to understand the development and use of the atomic bomb against Japan and the end of World War II. Settle's work is the only full-length study of Marshall's role in this critical moment in world history and its even-handed and thorough treatment of the subject is a model of clarity amidst the swirling controversy surrounding the use of the bomb. In light of Marshall's crucial role in the development of early Cold War U.S. national security strategy, this book is also essential reading for those interested in the origins and development of the Cold War nuclear arms race."

"This enlightening book by Professor Frank Settle fills a gaping hole in the literature of the nuclear age by explicating General George Marshall's leadership roles during the creation of atomic bombs in the Manhattan Project and management of nuclear weaponry after World War II. Without General Marshall's wise judgment and management skills, the United States might not have been able to make atomic bombs by the end of World War II even with the available immense scientific talent, and without his counsel after W.W. II as secretary of state and as secretary of defense, the United States might have detonated such weapons again."

"This is the first full-length study of Marshall's important role in the history of the atomic bomb—not only as army chief of staff during World War ll, but also through the early years of the Cold War as secretary of state and the first year of the Korean conflict when he was secretary of defense. As such it constitutes an important and useful addition to our knowledge of this key individual and the early history of U.S. nuclear policies."

"In the pantheon of American soldier-statesmen, from Washington to Eisenhower, Frank Settle is convincing that there was no one wiser and more admirable than George C. Marshall. Deeply researched and absorbing."
