I have seen a number of biographies, most of which have mixed reviews. What i am looking for is one accessible to a non-historian reader ( but a reader with some background knowledge in the area).
Thanks much.
Hey there!
So, I'm not sure what you've read already, but I can personally recommend The Rickover Effect: How One Man Made a Difference by Theodore Rockwell, an engineer who personally worked with Rickover for some fifteen years. This book is as much of a memoir (relating Rockwell's experiences with Rickover) as it is a biography of the admiral, but I would still say it to be one of the better, more accessible (to a non-historian reader as you specified) works. Other reviews I've seen tend to praise it as well, for what its worth.
As a side note, Rockwell also recommends (in the introduction of his book) Nuclear Navy: 1946-1962 and Rickover and the Nuclear Navy as sources he drew from.
Hope this helps!
