Explore the scientific crescendo of the Manhattan Project through newly contextualized and never-before-seen photographs from Los Alamos National Laboratory’s legacy collections—some just declassified.
 
Twenty-one days before the world learned of the atomic bomb through its wartime use against Japan, a team of scientists led by J. Robert Oppenheimer detonated the first nuclear device on a remote stretch of New Mexico desert, in an operation codenamed Trinity. Both a military proof test and an elaborate, well-documented scientific experiment, the Trinity shot on July 16, 1945, brought under the control of humankind a new fire: the energy of the atom.
 
In this expertly curated journey through the beginning of the atomic age, hundreds of carefully restored photographs, still frames, and once-secret documents bring new and vivid focus to a watershed moment in science and history. Written for all to understand, Trinity weaves steadily through subplots and surprises set against the evolving, looming backdrop of a world at war. It shadows the humans and hardware at work in the rugged landscape of the test operation; dissects a fiery mushroom cloud unfurling frame by frame, frozen in time; and follows soldiers, scientists, and two atomic bombs across the Pacific Ocean to Tinian Island, onto the strike planes Enola Gay and Bockscar, and to Hiroshima and Nagasaki, the two Japanese cities devastated on August 6 and 9, 1945.
 
Inviting readers into the clandestine spaces where a new era began—behind the cameras, the bunker doors, the gates and guard posts—Trinity strives, grieves, celebrates, and ponders. It artfully captures that extraordinary summer when scientists invented urgently in the waning months of the “before”—and the tension between violence and progress, hope and fear, that persists into the after.

“Featuring hundreds of carefully restored photographs, still frames, maps, and once-top-secret documents, this book is a visual journey through the very first atomic test, codenamed Trinity, that was conducted in the New Mexico desert in 1945. The stunning imagery paints a vivid picture of an emerging and destructive technology and the very human experience of bringing it into being.”

"Through several hundred previously classified photographs and documents,  Seyl’s Trinity: An Illustrated History of the World’s First Atomic Test tells the story of the human and scientific efforts that led to humanity commandeering the atom’s power. . . . Trinity meticulously illustrates just how many people and resources it required. Seyl says she intended her book to be an immersive experience that could help readers understand the test’s history and intricacies better, helping them build a foundation for thinking about nuclear weapons now. . . . The Trinity test changed everything, and we live in that changed world now."

“Many books describe how the first atomic bomb was built. But this history by Seyl stands apart. It tells the story of the bomb’s Trinity test in New Mexico in July 1945 through restored photographs from the Los Alamos National Laboratory’s National Security Research Center, where Seyl works. These include images of once-clandestine documents and experiments, as well as unfamiliar restored photographs of ‘trinitite’—green glass found at the test crater—which fell from the bomb’s fireball in molten drops.”

"A new book about the Trinity test, the world’s first atomic explosion, presents startlingly vivid views of the event. Based on a twenty-year effort to restore and release hundreds of photographs taken during the Manhattan Project, the book, simply titled Trinity, is a treasure trove of some 350 of these images, along with maps, memos, diagrams, blueprints, and pictures of lab-notebook pages."

"

"The great mushroom cloud of an atomic or hydrogen bomb detonation has been called 'a thing of terrible beauty.' Indeed, at its most dramatic, Seyl’s illustrated history of the inaugural atomic bomb test, and beyond, possesses a hypnotic, terrifying majesty. The experience of reading this book is both admiring and unsettling. . . . A singular event captured in ordinary—and extraordinary—images."

"

"Stunning. . . . To honor the complexity of the Manhattan Project, great care is taken to communicate the manifold, intricate procedures of the Trinity test in an inclusive, understandable fashion. Exceptional descriptions reveal the labyrinthine procedures and mind-boggling feats of logistics, forming digestible, enlightening paragraphs that respect the complexity of the operation itself. Indeed, the sheer breadth of the book’s coverage is staggering. Images of maps, schematics, laboratories, staff at work, the testing grounds, classified documents, handwritten notes, and leading-edge recording equipment can all be found within, each with its own informative caption. It is the most comprehensive visual record of the Trinity detonation ever assembled, containing restored images of the blast that have only just become public. . . . Trinity is an amazing photographic history of the revolutionary test that kicked off the atomic age."

“This illustrated history of the world’s first atomic test features hundreds of fully restored photographs and still frames from the Trinity site during the setup, execution, and aftermath of the test. Most images are drawn from the archives of Los Alamos National Laboratory in New Mexico. These visual artifacts form magnificent, often two-page spreads that depict scientists and soldiers, diagrams, maps, documents, buildings, industrial equipment, and nuclear devices. Hundreds of scientists and soldiers monitored the test while hundreds of cameras and scientific instruments recorded the explosion and aftermath. Cameras also recorded events at Tinian Island, where two atomic bombs were prepped for deployment, and documented the devastation wrought by the bombing of Japan.”
