This volume, prepared by an acknowledged expert on the Manhattan Project, gives a concise, fast-paced account of all major aspects of the project at a level accessible to an undergraduate college or advanced high-school student familiar with some basic concepts of energy, atomic structure, and isotopes. The text describes the underlying scientific discoveries that made nuclear weapons possible, how the project was organized, the daunting challenges faced and overcome in obtaining fissile uranium and plutonium, and in designing workable bombs, the dramatic Trinity test carried out in the desert of southern New Mexico in July 1945, and the bombings of Hiroshima and Nagasaki.

“Groueff, a Paris-Match reporter, was sponsored by The Reader’s Digest to write this prodigious account of the multiple efforts which went into the creation of the first atomic bomb between 1942 and 1945. The book is a history of the men involved, mainly; and Groves, the military commander, is obviously the author’s hero. Reading like the account of a hurdle race, the book charges into a discussion of a problem, then ‘finds’ and describes the man who bested it. Thus are described the building of Oak Ridge, Fermi’s atomic pile, the electromagnetic process, the crises over the barrier and the valves for the gaseous diffusion process, the last-minute decisions concerning the implosion process with plutonium. Groueff does convey well a scene of fantastic activity, where different solutions to one problem were worked on simultaneously, where industrial equipment came before scientific results were known, where the ‘impossible’ was achieved — in time. The material is fascinating, and the scientific information is well presented... [an] excellent overall view of a monumental project.” — Kirkus “Groueff has for the first time given due recognition to some of the minor figures, particularly engineers and technicians, and has preserved in his pages much information that would otherwise perish with the participants or lie forever buried in the archives.” — Kendall Birr, The American Historical Review “Groueff... covers the Manhattan Project from its beginning in 1942 to the bombing of Hiroshima... [he] concentrates on the engineering and industrial effort that went into producing the first atomic weapons... The result is a popular but responsible account, episodic in structure, rich in detail and human interest... for the first time a book aimed at the mass market gives engineers and industrialists their due. It is a great story of the almost incredibly complex task of translating theory into industrial and military reality.” — Oscar E. Anderson, Jr., Science “So intriguing in fact and in style is the text of the narrative of this book that, once begun, it cannot be put down until the end... In these pages the names and roles of some of the world’s greatest scientists and engineers unfold in thrilling parade, with Dr. Vannevar Bush the leader. These men of vast knowledge and ability unite with the commercial managers and their companies mobilized by the hundreds for the construction and operation of the many facilities involved.” — Leo A. Codd, Ordnance “Excellent... maintains a high degree of exciting suspense.” — Washington Star “A fascinating account of a stupendous effort.” — Chicago Tribune

Though thousands of articles and books have been published on various aspects of the Manhattan Project, this book is the first comprehensive single-volume history prepared by a specialist for curious readers without a scientific background. This project, the United States Army’s program to develop and deploy atomic weapons in World War II, was a pivotal event in human history. The author presents a wide-ranging survey that not only tells the story of how the project was organized and carried out, but also introduces the leading personalities involved and features simplified but accurate descriptions of the underlying science and the engineering challenges. The technical points are illustrated by reader-friendly graphics. .

The development of atomic bombs under the auspices of the U.S. Army’s Manhattan Project during World War II is considered to be the outstanding news story of the twentieth century. In this book, a physicist and expert on the history of the Project presents a comprehensive overview of this momentous achievement. The first three chapters cover the history of nuclear physics from the discovery of radioactivity to the discovery of fission, and would be ideal for instructors of a sophomore-level “Modern Physics” course. Student-level exercises at the ends of the chapters are accompanied by answers. Chapter 7 covers the physics of first-generation fission weapons at a similar level, again accompanied by exercises and answers. For the interested layman and for non-science students and instructors, the book includes extensive qualitative material on the history, organization, implementation, and results of the Manhattan Project and the Hiroshima and Nagasaki bombing missions. The reader also learns about the legacy of the Project as reflected in the current world stockpiles of nuclear weapons. This second edition contains important revisions and additions, including a new chapter on the German atomic bomb program and new sections on British and Canadian contributions to the Manhattan project and on feed materials. Several other sections have been expanded; reader feedback has been helpful in introducing minor corrections and improved explanations; and, last but not least, the second edition includes a detailed index.

On the seventy-fifth anniversary of the first atomic bomb, discover new reflections on the Manhattan Project from President Barack Obama, hibakusha (survivors), and the modern-day mayors of Hiroshima and Nagasaki. The creation of the atomic bomb during World War II, codenamed the Manhattan Project, was one of the most significant and clandestine scientific undertakings of the 20th century. It forever changed the nature of war and cast a shadow over civilization. Born out of a small research program that began in 1939, the Manhattan Project would eventually employ nearly 600,000 people and cost about $2 billon ($28.5 billion in 2020) -- all while operating under a shroud of complete secrecy. On the 75th anniversary of this profoundly crucial moment in history, this newest edition of The Manhattan Project is updated with writings and reflections from the past decade and a half. This groundbreaking collection of essays, articles, documents, and excerpts from histories, biographies, plays, novels, letters, and oral histories remains the most comprehensive collection of primary source material of the atomic bomb.

**Winner of the Pulitzer Prize, the National Book Award, and the National Book Critics Circle Award** The definitive history of nuclear weapons—from the turn-of-the-century discovery of nuclear energy to J. Robert Oppenheimer and the Manhattan Project—this epic work details the science, the people, and the sociopolitical realities that led to the development of the atomic bomb. This sweeping account begins in the 19th century, with the discovery of nuclear fission, and continues to World War Two and the Americans’ race to beat Hitler’s Nazis. That competition launched the Manhattan Project and the nearly overnight construction of a vast military-industrial complex that culminated in the fateful dropping of the first bombs on Hiroshima and Nagasaki. Reading like a character-driven suspense novel, the book introduces the players in this saga of physics, politics, and human psychology—from FDR and Einstein to the visionary scientists who pioneered quantum theory and the application of thermonuclear fission, including Planck, Szilard, Bohr, Oppenheimer, Fermi, Teller, Meitner, von Neumann, and Lawrence. From nuclear power’s earliest foreshadowing in the work of H.G. Wells to the bright glare of Trinity at Alamogordo and the arms race of the Cold War, this dread invention forever changed the course of human history, and The Making of The Atomic Bomb provides a panoramic backdrop for that story. Richard Rhodes’s ability to craft compelling biographical portraits is matched only by his rigorous scholarship. Told in rich human, political, and scientific detail that any reader can follow, The Making of the Atomic Bomb is a thought-provoking and masterful work.

A history of the origins and development of the American atomic bomb program during WWII. Begins with the scientific developments of the pre-war years. Details the role of the U.S. government in conducting a secret, nationwide enterprise that took science from the laboratory and into combat with an entirely new type of weapon. Concludes with a discussion of the immediate postwar period, the debate over the Atomic Energy Act of 1946, and the founding of the Atomic Energy Commission. Chapters: the Einstein letter; physics background, 1919-1939; early government support; the atomic bomb and American strategy; and the Manhattan district in peacetime. Illustrated.

During World War II, the lives of millions of Americans lay precariously in the hands of a few brilliant scientists who raced to develop the first weapon of mass destruction. Elected officials gave the scientists free rein in the Manhattan Project without understanding the complexities and dangers involved in splitting the atom. The Manhattan Project was the first example of a new type of choice for congressmen, presidents, and other government officials: life and death on a national scale. From that moment, our government began fashioning public policy for issues of scientific development, discoveries, and inventions that could secure or threaten our existence and our future. But those same men and women had no training in such fields, did not understand the ramifications of the research, and relied on incomplete information to form potentially life-changing decisions. Through the story of the Manhattan Project, Neil J. Sullivan asks by what criteria the people in charge at the time made such critical decisions. He also ponders how similar judgments are reached today with similar incomprehension from those at the top as our society dives down the potential rabbit hole of bioengineering, nanotechnology, and scientific developments yet to come.

General Leslie Groves and J. Robert Oppenheimer were the two men chiefly responsible for the building of the first atomic bomb at Los Alamos, code name "The Manhattan Project." As the ranking military officer in charge of marshalling men and material for what was to be the most ambitious, expensive engineering feat in history, it was General Groves who hired Oppenheimer (with knowledge of his left-wing past), planned facilities that would extract the necessary enriched uranium, and saw to it that nothing interfered with the accelerated research and swift assembly of the weapon.This is his story of the political, logistical, and personal problems of this enormous undertaking which involved foreign governments, sensitive issues of press censorship, the construction of huge plants at Hanford and Oak Ridge, and a race to build the bomb before the Nazis got wind of it. The role of groves in the Manhattan Project has always been controversial. In his new introduction the noted physicist Edward Teller, who was there at Los Alamos, candidly assesses the general's contributions-and Oppenheimer's-while reflecting on the awesome legacy of their work.

The compelling photographs from the Manhattan Project, by turns specific, abstract, dramatic, and surreal, offer a multifaceted look at history. Photographs of landscapes and of construction, of scientific experiments and their results, are framed against official portraits and casual snapshots.
