Hyman G. Rickover

Hyman George Rickover (January 27, 1900 – July 8, 1986) was a four-star admiral of the United States Navy who directed the original development of naval nuclear propulsion and controlled its operations for three decades as director of Naval Reactors. In addition, he oversaw the development of the Shippingport Atomic Power Station, the world's first commercial pressurized water reactor used for generating electricity.

Rickover is known as the "Father of the Nuclear Navy", which as of July 2007 had produced 200 nuclear-powered submarines, and 23 nuclear-powered aircraft carriers and cruisers, though many of these U.S. vessels are now decommissioned and others under construction.

On 16 November 1973 Rickover was promoted to four-star admiral after 51 years of commissioned service. With his unique personality, political connections, responsibilities, and depth of knowledge regarding naval nuclear propulsion, Rickover became the longest-serving naval officer in U.S. history with 63 years active duty.

Rickover's substantial legacy of technical achievements includes the United States Navy's continuing record of zero reactor accidents, as defined by the uncontrolled release of fission products subsequent to reactor core damage.
