Hidden Photos Reveal Manhattan Project Trinity Test Legacy

Emily Seyl, a writer and editor at Los Alamos National Laboratory's National Security Research Center, discusses her new book 'Trinity' — a 20-year effort to restore and contextualize hundreds of photographs from the Manhattan Project's Trinity test, the world's first atomic explosion. The book, published by University of Chicago Press, contains around 350 images alongside maps, memos, and blueprints documenting the 1945 test. Seyl reflects on the importance of archival stewardship, the serendipitous timing with the Oppenheimer film, and how specific photographs helped her reconstruct the physical layout of the Trinity test site.
