Biography of a less well known American hero. Deak Parsons, New Mexico raised, Navy educated, was the technical genius behind the fusing of the first atomic weapon. Post WWII, he drove development of the nuclear Navy. Parsons was a critical person in the atomic development of WWII, this is the only story that I could find about him...written by a one book author. I found the book online for a penny. The story develops nicely, chronologically for the most part. The book's flow runs from his boyhood, through relationships developed at the Naval Academy, and includes alternate assignments in the operational Navy and technical scientific assignments. It illuminates Deak's participation in the Manhattan project as well as Navy contributions to the same. Post war projects come next, followed by an operational assignment and his death while serving in the Pentagon. It's well documented--an academic would be proud. ( )
