Harold Agnew

Harold Agnew worked on the Manhattan Project at various locations and served as the director of the Los Alamos National Laboratory from 1970-1979. Agnew was flying above Hiroshima as a scientific observer when the bomb was dropped, and remembers “having the blast hit the airplane after the flash, the very bright flash.” He worked on the Chicago Pile-1 with Enrico Fermi, whom he calls “absolutely amazing.” He recalls how Oppenheimer’s penchant for treating everyone equally and General Leslie Groves’ incredible managing skills influenced camaraderie and the speed of the project. He defends dropping the bombs on Japan as saving many American, Japanese, and Chinese lives.
