John L. Sullivan (United States Navy)

Born in Manchester, New Hampshire, Sullivan was an alumnus of Dartmouth College.[1] He graduated from Harvard Law School in 1924. Sullivan served as Assistant Secretary of the Treasury in 1940–44, Assistant Secretary of the Navy (AIR) in 1945–46, and as Under Secretary of the Navy in 1946–47.

Sullivan was appointed Secretary of the Navy upon James Forrestal's installation as the first Secretary of Defense. Sullivan's major contributions to the Navy's future directions include the advent of naval nuclear propulsion. In 1947, then-Captain Hyman G. Rickover went around his chain-of-command and directly to the Chief of Naval Operations, Fleet Admiral Chester W. Nimitz, by chance also a former submariner, to pitch his ideas for creating a nuclear-powered warship. Nimitz immediately understood the potential of nuclear propulsion and recommended the project to Sullivan, whose endorsement to build the world's first nuclear-powered vessel, USS Nautilus (SSN-571), later caused Rickover to state that Sullivan was "the true father of the Nuclear Navy."[2][3] In May 1949, Sullivan resigned in protest after the second Secretary of Defense, Louis A. Johnson, canceled the heavy aircraft carrier United States. This event was part of an interservice conflict known as the Revolt of the Admirals.

Sullivan and his wife had two daughters and a son. Sullivan died on August 8, 1982.[4] He is buried in Arlington National Cemetery.
