Summary
The Pioneers of Atomic Science
Rhodes paints a vivid portrait of the scientific minds that, until World War II, laid the groundwork for humanity's first atomic bomb. This international coalition of physicists and chemists brought ancient Greek musings about atomic particles into the modern age. As early as the seventeenth century, the atom was a hypothetical cornerstone of scientific thought, yet its existence remained unproven until J. J. Thomson unveiled the electron in 1897. Thomson, then at the helm of the renowned Cavendish Laboratory at Cambridge, wielded significant influence over the scientific luminaries of his era. Einstein unveiled his groundbreaking theory of relativity in 1915. Leo Szilard, a Hungarian-born Jewish theoretical physicist, embarked on his scientific journey at the University of Berlin in 1921, where he collaborated with Einstein. Ernest Rutherford, a pioneering New Zealand-born British physicist, is celebrated for crafting the field of nuclear physics. Under Thomson's tutelage at the Cavendish Laboratory, Rutherford ascended to become its director in 1919, where he conceived the Rutherford atomic model.
Niels Bohr, a visionary Danish physicist, revolutionized our understanding of atomic structure with his Bohr atomic model. In 1921, Bohr took charge of the Institute for Theoretical Physics in Copenhagen, transforming it into a global hub for quantum theory and atomic research. Bohr's innovative application of quantum theory to atomic and molecular particles marked a new chapter in science. Robert J. Oppenheimer, an American theoretical physicist, honed his expertise in atomic physics under Rutherford's guidance at the Cavendish Laboratory. By 1927, Oppenheimer had joined the faculty at the University of California at Berkeley and the California Institute of Technology. In 1932, James Chadwick, an English physicist who partnered with Rutherford at the Cavendish Laboratory, made the groundbreaking discovery of the neutron. Concurrently, German chemist Otto Hahn, alongside Fritz Strassmann, unraveled the mystery of nuclear fission. In Italy, the brilliant physicist Enrico Fermi advanced the study of nuclear fission at the University of Rome.
The ascent of Hitler in 1933 prompted a diaspora of Europe’s scientific elite, many seeking refuge in the United States to escape Nazi tyranny. Szilard found temporary sanctuary in London, where he first envisioned the atomic bomb, before relocating to Columbia University in the United States. Einstein, facing a grave threat due to his global renown, sought safety at the Institute for Advanced Study at Princeton University. Under the guise of receiving a Nobel Prize in 1938, Fermi fled fascist Italy for America. Meanwhile, Meitner escaped Nazi Germany in 1938 to continue her research with nephew Otto Frisch in Sweden. As World War II loomed and Nazi Germany invaded Denmark, Bohr and his family fled, seeking asylum first in England, then in the United States.
The Genesis of the Manhattan Project
In 1939, upon reaching New York, Bohr warned Einstein of Germany's potential to craft an atomic bomb. United with fellow scientists, Bohr persuaded Einstein to pen a letter to President Franklin D. Roosevelt, urging American research into atomic weaponry. Initially, the magnitude of this scientific revelation eluded government officials. It was the cataclysm of Pearl Harbor in December 1941 that thrust the United States into World War II, prompting renewed urgency for developing military innovations. This urgency birthed the clandestine Manhattan Project in May 1942, an ambitious collaboration of American and British scientists spread across locations like the University of Chicago and Los Alamos, New Mexico. The initiative also took root in Berkeley, Columbia University in New York City, and Oak Ridge, Tennessee, all coordinated under the Manhattan Engineer District Office. On July 16, 1945, the inaugural atomic bomb test, "Trinity," detonated successfully at an air base in...

Alamogordo, New Mexico. Concurrently, scientists in Britain, Germany, Japan, and Russia were on parallel paths towards the same atomic ambitions, albeit stymied by various deterrents.
The Shadows of Hiroshima and Nagasaki
The Transition of Power
On the significant day of April 12, 1945, the world witnessed the passing of President Franklin D. Roosevelt, ushering Vice President Harry S. Truman into the presidency of the United States. Up until that momentous occasion, Truman possessed only a shadowy understanding of the Manhattan Project's monumental goals. However, he soon found himself enlightened to the profound magnitude of its endeavors.
The Surrender and the Potsdam Conference
As the calendar turned to May 1945, Germany's surrender to the Allies marked a historic milestone. Subsequently, diplomatic discussions commenced at the Potsdam Conference, nestled in the suburbs of Berlin, spanning from July 17 to August 2, 1945. Here, the stage was set for the strategic musings of the illustrious Big Three: President Truman of the United States, Prime Minister Winston Churchill of Great Britain, and Premier Joseph Stalin of Russia.
The Unyielding Call and Devastating Impact
With the curtain closing on the European conflict, the Allies delivered an uncompromising ultimatum from Potsdam to Japan, demanding unconditional surrender. However, Japan's refusal to yield led to a cataclysmic turn of events. On August 6, 1945, the United States unleashed the first offensive atomic bomb over Hiroshima, Japan. The explosive force, ominously dubbed Little Boy, was delivered by the modified B-29 bomber Enola Gay, piloted by Colonel Paul Tibbets.
The Relentless Aftermath
Despite Emperor Hirohito's willingness to capitulate, the staunch resistance of the Japanese military prompted the United States to deploy a second bomb. On August 9, the city of Nagasaki bore the brunt of Fat Man's destruction. In the aftermath, Japan surrendered unconditionally to the Allies. The bombings left both cities in utter ruin; Hiroshima, once home to 350,000 souls, mourned the loss of 140,000 lives and saw two-thirds of its infrastructure obliterated. Nagasaki suffered similarly, with 70,000 of its 270,000 residents perishing and half of the city reduced to rubble.
The Dawn of a New Era
In the war's wake, the United States embarked on the ambitious pursuit of an even greater destructive force: the hydrogen bomb. The world stood poised on the brink of a new era, shaped by the unfathomable power of atomic energy.
