Via The Instapundit we have a link that goes to a story on then Navy Captain Hyman Rickover. Interestingly, Admiral was an immigrant from a Polish Shtetl before WWII. During WWII his village of origin was wiped out by the Germans under GENERALPLAN OST.
Admiral Rickover, commissioned out of the Naval Academy in 1922, had to deal with the ingrained anti-Semetism of the US Navy of the day, which he did by hard work and efficiency.
