Query: Rickover: Interesting Details, but Overlong

Worth reading if this is your area. The book describes Rickover as dominating, selfish, obsessed, power-hungry, dictatorial - but of immense value to our country because of the way he directed his ambitions. Interesting: How he exploited Congressmen to support him; how his superiors and peers despised him, yet envied his brilliance, how he interviewed and selected staff. Not interesting: Endless details on appropriations; differences between various sub propulsion designs. The book is solid and well-written, but unless you are interested in this arcane area, you can find more interesting biographies. And beware: Because this was unauthorized, Rickover and his staff did not participate and many of the inputs from others are of the vicious, jealous type, so the whole man does not come through in this book very well.
