An interesting perspective on the Manhattan Project. I would have liked more technical detail -- but it was probably classified when this was written, and the focus is very much on the people involved.
I noted that Lamont doesn't always agree with Richard Feynman's recollections of the same events in his memoirs -- e.g. Feynman found building Los Alamos exciting, while Lansing reports that it drove the managers and engineers crazy.
