In this episode of NPR's Book of the Day, Garrett Graff examines the history of the atomic bomb, from its development during World War II through its use on Japan. The discussion covers the Manhattan Project's origins, sparked by fears of Nazi Germany developing nuclear weapons first, and explores the massive scale of the secret operation that employed over 100,000 people across multiple facilities.
The episode delves into firsthand accounts from survivors of Hiroshima and Nagasaki, who described experiences that challenged normal human perception. It also addresses the ongoing debates about the decision to use atomic weapons, examining arguments both for and against their deployment, while considering the weapons' impact on international relations since World War II, including current nuclear proliferation concerns in regions like India and Pakistan.

The Manhattan Project, one of the most secretive endeavors in US history, emerged from fears that Nazi Germany would develop nuclear weapons first. European scientists who had fled fascism in the 1930s warned the United States about this possibility, creating a sense of urgency that drove the project forward.
The project brought together an unprecedented collaboration of scientists, engineers, and workers across multiple secret facilities. Notable sites included Oak Ridge and Hanford, which employed over 100,000 people in facilities spanning 50 square miles. Remarkably, high school girls at Oak Ridge, hired due to wartime labor shortages, proved more efficient at uranium refinement than PhD scientists, despite not knowing the purpose of their work.
Survivors of Hiroshima and Nagasaki described experiences that defied normal human perception. One child reported "feeling colors," while others struggled to describe the otherworldly light of the blast. The devastation was so severe that survivors reported victims "did not look human." According to Garrett Graff, while the bombings ultimately led to Japan's surrender, it took Emperor Hirohito's intervention following a failed coup by hard-right factions who wanted to continue fighting.
The decision to use atomic weapons remains controversial. Proponents argue it prevented greater casualties from a potential invasion of Japan, while critics question the moral implications of the immense human toll. Graff notes that nuclear weapons have defined international geopolitics since WWII, with ongoing concerns about proliferation, particularly in regions like India and Pakistan, which represent the largest nuclear arsenals to have ever been in open conflict.
1-Page Summary
The atomic bomb was developed due to fears that Nazi Germany would be the first to harness nuclear technology for warfare, which led to one of the most significant and secret endeavors in US history: the Manhattan Project.
Europe's scientists, many of whom fled fascism in the 1930s, conveyed a sense of urgency to the United States about the potential of nuclear weaponry. They feared that if Adolf Hitler acquired the atomic bomb first, the consequences could be catastrophic.
In the tense atmosphere of 1942, as the world was engulfed in WWII, discussions escalated about the possibility that German scientists were progressing toward creating atomic weapons for Hitler. This pressing fear catalyzed discussions and actions in the United States.
As the University of Chicago team toiled to construct the first chain reaction reactor, one of the scientists underscored the rush in their task, believing that their counterparts in Germany were engaged in a race to develop Hitler's bomb.
The Manhattan Project remains one of the most secretive and extensive efforts to harness science and industry in the service of warfare.
The Project brought together a brain trust of scientists from Chicago, Berkeley, Pri ...
Origins and Motivations Behind the Atomic Bomb Development
The Manhattan Project is a historical example of an unprecedented mobilization effort, demonstrating the massive scale at which the United States operated during World War II.
The Manhattan Project was an enormous undertaking that exemplified the industrial and logistical might of the United States.
Vast, secret cities integral to the Manhattan Project spanned an extensive area of 50 miles wide by 50 miles long, yet they were so covert they didn’t appear on maps. These cities played a pivotal role in research and production activities related to the development of the atomic bomb.
The effort to build the bomb brought together not just scientists but also engineers, leaders, and students, among others. This diverse group of contributors, which could be described as a mix of "artisans and gamblers," made the realization of the atomic bomb possible through their combined expertise and dedicatio ...
The Logistics and Scale of the Manhattan Project
The atomic bombings of Hiroshima and Nagasaki had a profound impact on survivors, the course of WWII, and the international community. The toll was devastating and the legacy complex, with differing views on the necessity and morality of the bombings.
Survivors have recounted their experiences in the wake of the bombings in haunting detail, painting a picture of horror and surreal devastation experienced during and after the events.
Children who lived through Hiroshima described the bombings in haunting terms. The intensity and otherworldly nature of the explosion were so extreme that one child expressed the experience as "I felt colors," a testament to the sensory overload caused by the bomb. Another was at a loss for words, unable to describe the light that resulted from the atomic blast, indicating that the human senses were ill-equipped to process the enormity of the event.
The chaos and devastation that ensued were such that one survivor noted the victims “did not look like human beings.” The statement highlights the dehumanizing effect of the bombing's aftermath, with devastating injuries that left victims unrecognizable and stripped of their humanity in the eyes of those who witnessed the carnage.
The bombings of Hiroshima and Nagasaki are widely seen as the events that ultimately led to the end of World War II, but the way they brought about the conclusion of the conflict is still subject to moral debate.
Garrett Graff points out that hard-right factions of the Japanese government were unwill ...
Human Impact and Legacy of Atomic Bombings
Garrett Graff's oral history provides a perspective on nuclear weapons' historical and current implications, particularly focusing on the atomic bomb's use in World War II.
There's an ongoing debate about whether the decision to use atomic bombs on Hiroshima and Nagasaki was a necessary evil or an indefensible act.
Proponents of the decision argue that it was made against the backdrop of the deadliest conflict in human history, with the goal of ending the war promptly. They contend that using atomic bombs prevented greater loss of life that would have resulted from continued conventional warfare and a potential invasion of Japan.
Critics of the atomic bomb decision question the moral justification of such an act, highlighting the immense human toll and long-lasting trauma inflicted upon the populations of Hiroshima and Nagasaki.
As Graff discusses, the legacy of the atomic bombs is the def ...
