Hyman George Rickover (27 January 1900 – 8 July 1986) was an admiral in the United States Navy. He directed the original development of naval nuclear propulsion and controlled its operations for three decades as director of the U.S. Naval Reactors office. 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 also one of seven people who have been awarded two Congressional Gold Medals.
Rickover is known as the "Father of the Nuclear Navy," and his influence on the Navy and its warships was of such scope that he "may well go down in history as one of the Navy's most important officers." He served in a flag rank for nearly 30 years (1953 to 1982), ending his career as a four-star admiral. His years of service exceeded that of each of the U.S. Navy's five-star fleet admirals—Leahy, King, Nimitz and Halsey—all of whom served on active duty for life after their appointments. Rickover's total of 63 years of active duty service makes him the longest-serving naval officer, as well as the longest-serving member of the U.S. armed forces in history.
Having become a naval engineering duty officer (EDO) in 1937 after serving as both a surface ship and submarine-qualified unrestricted line officer, his substantial legacy of technical achievements includes the United States Navy's continuing record of zero reactor accidents.
Early life and education Rickover was born Chaim Gdala Rykower to Abraham and Rachel/Ruchla Lea (née Unger) Rykower, a Polish Jewish family from Maków Mazowiecki in Vistula Land. His parents changed his name to "Hyman" which is derived from Chayyim, meaning "life". He did not use his middle name Godalia (a form of Gedaliah), but he substituted "George" when at the Naval Academy.
In 1906 (aged six), Rickover made passage to New York City with his mother and sister, fleeing anti-Semitic Russian pogroms during the Revolution of 1905. They joined Abraham, who had made earlier trips there beginning in 1897 to become established. Rickover's family lived initially on the East Side of Manhattan but moved two years later to North Lawndale, Chicago, which was a heavily Jewish neighborhood at the time, where Rickover's father continued work as a tailor. Rickover took his first paid job at age nine, earning three cents an hour () for holding a light as his neighbor operated a machine. Later, he delivered groceries. He graduated from grammar school at 14.
Rickover attended John Marshall Metropolitan High School in Chicago and graduated with honors in 1918. He then held a full-time job as a telegraph boy delivering Western Union telegrams, through which he became acquainted with Congressman Adolph J. Sabath, a Czech Jewish immigrant. Sabath nominated Rickover for appointment to the United States Naval Academy. Rickover was only a third alternate for appointment, but he passed the entrance exam and was accepted.
Naval career through World War II Rickover's naval career began in 1918 at the Naval Academy; at this time, attending military academies was considered active duty service, due in part to World War I. On 2 June 1922, Rickover graduated 107th out of 540 midshipmen and was commissioned as an ensign. He joined the destroyer on 5 September 1922. Rickover impressed his commanding officer with his hard work and efficiency, and was made engineer officer on 21 June 1923, becoming the youngest such officer in the squadron.
He next served on board the battleship before earning a Master of Science degree in electrical engineering from Columbia University in 1930 by way of a year at the Naval Postgraduate School and further coursework at Columbia.
Rickover had a high regard for the quality of the education he received at Columbia, as demonstrated in this excerpt from a speech he gave at the university some 52 years after attending:
Rickover preferred life on smaller ships, and he also knew that young officers in the submarine service were advancing quickly, so he went to Washington and volunteered for submarine duty. His application was turned down due to his age, at that time 29 years. Fortunately for Rickover, he encountered his former commanding officer from Nevada while leaving the building, who interceded successfully on his behalf. From 1929 to 1933, Rickover qualified for submarine duty and command aboard the submarines and . While aboard S-48 he was addressed a letter of commendation from the Secretary of the Navy "for rescuing Augustin Pasis ... from drowning at the Submarine Base, Coco Solo, Canal Zone." While at the Office of the Inspector of Naval Material in Philadelphia, Pennsylvania in 1933, Rickover translated Das Unterseeboot (The Submarine) by World War I German Imperial Navy Admiral Hermann Bauer. Rickover's translation became a basic text for the U.S. submarine service.
On 17 July 1937, he reported aboard the minesweeper at Qingdao, China, and assumed what would be his only ship command with additional duty as Commander, Mine Division Three, Asiatic Fleet. The Marco Polo Bridge Incident had occurred ten days earlier. In August, Finch stood out for Shanghai to protect American citizens and interests from the conflict between Chinese and Japanese forces. On 25 September, Rickover was promoted to lieutenant commander, retroactive to 1 July. In October, his designation as an engineering duty officer became effective, and he was relieved of his three-month command of Finch at Shanghai on 5 October 1937.
Rickover was assigned to the Cavite Navy Yard in the Philippines, and was transferred shortly thereafter to the Bureau of Engineering in Washington, D.C. Once there, he took up his duties as assistant chief of the Electrical section of the Bureau of Engineering on 15 August 1939.
On 10 April 1942, after America's entry into World War II, Rickover flew to Pearl Harbor to organize repairs to the electrical power plant of . Rickover had been promoted to the rank of commander on 1 January 1942, and in late June of that year was made a temporary captain. In late 1944 he appealed for a transfer to an active command. He was sent to investigate inefficiencies at the naval supply depot at Mechanicsburg, Pennsylvania, then was appointed in July 1945 to command of a ship repair facility on Okinawa. Shortly thereafter, his command was destroyed by Typhoon Louise, and he subsequently spent some time helping to teach school to Okinawan children.
Later in the war, his service as head of the Electrical Section in the Bureau of Ships brought him a Legion of Merit and gave him experience in directing large development programs, choosing talented technical people, and working closely with private industry. Time magazine featured him on the cover of its 11 January 1954 issue. The accompanying article described his wartime service:
Naval Reactors and the Atomic Energy Commission
In December 1945, Rickover was appointed Inspector General of the 19th Fleet on the west coast, and was assigned to work with General Electric at Schenectady, New York, to develop a nuclear propulsion plant for destroyers. In 1946, an initiative was begun at the Manhattan Project's Clinton Laboratory (now the Oak Ridge National Laboratory) to develop a nuclear electric generating plant. Realizing the potential that nuclear energy held for the Navy, Rickover applied. Rickover was sent to Oak Ridge through the efforts of his wartime boss, Rear Admiral Earle Mills, who became the head of the Navy's Bureau of Ships that same year.
Rickover became an early convert to the idea of nuclear marine propulsion, and was the driving force for shifting the Navy's initial focus from applications on destroyers to submarines. Rickover's vision was not initially shared by his immediate superiors: he was recalled from Oak Ridge and assigned "advisory duties" with an office in an abandoned ladies' room in the Navy Building. He subsequently went around several layers of superior officers, and in 1947 went directly to the Chief of Naval Operations, Fleet Admiral Chester Nimitz, also a former submariner. Nimitz immediately understood the potential of nuclear propulsion in submarines and recommended the project to the Secretary of the Navy, John L. Sullivan. Sullivan's endorsement to build the world's first nuclear-powered vessel, , later caused Rickover to state that Sullivan was "the true father of the Nuclear Navy."
Subsequently, Rickover became chief of a new section in the Bureau of Ships, the Nuclear Power Division reporting to Mills. He began work with Alvin M. Weinberg, the Oak Ridge director of research, to initiate and develop the Oak Ridge School of Reactor Technology and to begin the design of the pressurized water reactor for submarine propulsion. In February 1949 he was assigned to the Atomic Energy Commission's Division of Reactor Development, and then assumed control of the Navy's effort within the as Director of the Naval Reactors Branch. This twin role enabled him to lead the effort to develop Nautilus.
The original selection of Rickover as head of development of the nation's nuclear submarine program ultimately rested with Admiral Mills. According to Lieutenant General Leslie Groves, director of the Manhattan Project, Mills was anxious to have a very determined man involved. He knew that Rickover was "not too easy to get along with" and "not too popular," but in his judgement Rickover was the man on whom the Navy could depend "no matter what opposition he might encounter".
While his team and industry were completing construction of Nautilus, Rickover was promoted to the rank of rear admiral in 1953. However, this was anything but routine, and occurred only after an extraordinary chain of events:
Regardless of the challenges faced in developing and operating brand-new technology, Rickover and the team did not disappoint: the result was a highly reliable nuclear reactor in a form-factor that would fit into a submarine hull with no more than a beam. This became known as the S1W reactor. Nautilus was launched and commissioned with this reactor in 1954.
Later Rickover oversaw the development of the Shippingport Atomic Power Station, the first commercial pressurized water reactor nuclear power plant. Kenneth Nichols of the AEC decided that the Rickover-Westinghouse pressurized-water reactor was "the best choice for a reactor to demonstrate the production of electricity" with Rickover "having a going organization and a reactor project under way that now had no specific use to justify it." This was a reference to the first core used at Shippingport originating from a cancelled nuclear-powered aircraft carrier. This was accepted by Lewis Strauss and the Commission in January 1954.
Rickover was promoted to vice admiral in 1958, the same year that he was awarded the first of two Congressional Gold Medals. He exercised tight control for the next three decades over the ships, technology, and personnel of the nuclear Navy, interviewing and approving or denying every prospective officer being considered for a nuclear ship. Over the course of Rickover's career, these personal interviews numbered in the tens of thousands; over 14,000 interviews were with recent college-graduates alone. The interviewees ranged from midshipmen and newly commissioned ensigns destined for nuclear-powered submarines and surface combatants, to very senior combat-experienced naval aviator captains who sought command of nuclear-powered aircraft carriers. The content of most of these interviews has been lost to history, though some were later chronicled in several books on Rickover's career, as well as in a rare personal interview with Diane Sawyer in 1984.
