The Making of the Atomic Bomb is one of the best books I have ever read. It's one of the few history of science books that I feel didn't get dragged down in details or gloss over things to be superficial.
The follow-up Dark Sun: The Making of the Hydrogen Bomb is also good, but not as well done as the former.
I was blown away after reading this book. It is by far the best book on general physics I have read. I recommend it to all parents to give their children the opportunity to read this book. I think it will change their lives and channel them to a love of physics (if they are so inclined). It is an example of how so few could influence so many.
Personal anecdote. I met Robert Oppenheimer's grandson a few years back and he mentioned that this book is one of the few books that treated his grandfather fairly.
