If you are a techno-geek; or, a physics or history student, you will find no finer book about the effort that and people who built the atomic bomb. I’ve worn out the first hardback copy of the book I purchased and the second is filled with hand-written notes. I highly recommend this.

Rhodes seminal publication provides an in-depth look into history and scale of US Manhattan Project and principal characters. Wonderful background Into genesis of World War II atomic bomb project and giants like Einstein, Oppenheimer, Bohr, Bethe, Szilard, Teller, Fermi, Ulam, Von Neumann, etc., Great background information on personal lives and motivations of scientists, politicians, and military leaders of the time. I really liked photographs and descriptions of educational, military, and scientific installations, and the enormous effort to win the race to develop atomic bomb. This book is written for the layman, historian, and scientist. Pulitzer Prize Winner - Highly Recommended!
