Who put nuclear power in submarines?

The "Father of the Nuclear Navy" who started it all with the Nautilus was one of my old bosses, Admiral Hyman G. Rickover. Rickover was the one who put it all together and made Nuclear propulsion for submarines and ships a reality. To date, the Navy has a perfect reactor operation record, and all due to his methods and leadership. There are a couple of quotes of his that are favorites of mine on my bio page if you're interested.

Rickover personally interviewed and selected every Engineering Officer in the Navy who wanted a Nuclear career - in doing so, he effectively made the CO's of every Nuclear vessel in the Navy, since line officers must be Engineer Officers first before they can command a Nuclear vessel.

One story widely known is that he used to have lunch with a prospective EO and watch to see if the person seasoned his food before or after tasting it. If he seasoned it before tasting, he was rejected - the reason being that if you season it before tasting, you're assuming that it needs it. The Nuclear Power program does not tolerate mistakes or assumptions of any kind. A single administrative mistake can cost an officer his career.
