ADM Hyman G. Rickover immigrated from Poland in 1905 as a child, fleeing anti-Semitic Russian extermination groups. He rose through the ranks of the United States Navy as a talented engineer and mediocre officer. Among other achievements, he pioneered the most important engineering development of the modern Navy: audit & surveillance programs.
He also created ship-based nuclear propulsion plants, for which he is better known.
These shipboard reactors enabled submarines to move faster, submerge for longer, and travel to places once-thought unreachable by humans. However, due to the radiation exposure, submariners were no longer considered human and thus were able to endure the harsh conditions necessary to operate these technological marvels.
Rickover and his nuclear reactors revolutionized the world’s navies, but the hard-earned technological capabilities of these plants were only the physical manifestation of Rickover’s genius. His true achievement was founding and running the United States’ premier bureaucratic quagmire- Naval Reactors. Rickover remained the steadfast tyrant of Naval Reactors (and, consequently, the United States Navy) for 33 long years until the demented President Reagan and his corrupt lacky, Secretary John Lehman, forced him to retire because General Dynamics paid them off.
