Trinity’s Key Players
In 1942, Colonel Leslie Groves, who had just completed building the Pentagon under budget and ahead of schedule was promoted to Brigadier General and assigned to command the Manhattan Project’s nation-wide effort – build the Los Alamos lab, the Oakridge TN and Hanford WA enrichment sites, and, when it was needed, Trinity. Knowing Germany was working on a fission bomb, he was also responsible for atomic intelligence gathering and Army special operations soldiers trained to attack German atomic assets. Groves was an unpopular, blunt and hot-tempered officer who knew little about physics, but he was an engineer and a dedicated and gifted career soldier who got things done. He appointed the brilliant J. Robert Oppenheimer as his Los Alamos Lab Director responsible for the development of the bomb that would be tested at Trinity.
