The Making of the Atomic Bomb

There was quite a bit of what I was looking for, a history of the engineering and science behind the development of the first fission bomb. But it was wrapped in too much about the histories, relationships and personalities of the scientists involved. Add in the politics of the time and ethical debates and over a third of the book was about stuff I wasn't interested in.
It was deeply researched and very thorough but I wanted to know more about how such large organizations were created so fast, how the shear scale of the processing plants was managed, what new engineering techniques had to be developed to allow laboratory methods to be run as a giant industries. It was a good book, just not what I wanted. I'm glad I read it.
