John Lawrence Sullivan (June 16, 1899 – August 8, 1982) was an American lawyer who served in several positions in theUS federal government, including asSecretary of the Navy, the first during the administration ofHarry S. Truman.
Sullivan was born inManchester, New Hampshire on June 16, 1899. He was an alumnus ofDartmouth College. He graduated fromHarvard Law School in 1924.[1]
Sullivan served asAssistant Secretary of the Treasury in 1940–44,Assistant Secretary of the Navy (AIR) in 1945–46, notable as the first civilian sworn into Naval office aboard a ship in an active combat zone,[2] and asUnder Secretary of the Navy in 1946–47.

Sullivan was appointedSecretary of the Navy uponJames Forrestal's installation asSecretary of Defense. Sullivan's major contributions to the Navy's future directions include the advent ofnaval nuclear propulsion. In 1947, then-CaptainHyman G. Rickoverwent around his chain-of-command and directly to the Chief of Naval Operations, Fleet AdmiralChester 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."[3][4]
In May 1949, Sullivan resigned in protest after the second Secretary of Defense,Louis A. Johnson, canceled the heavyaircraft carrierUSS United States (CVA-58). This event was part of aninterservice conflict known as theRevolt of the Admirals.
Sullivan and his wife had two daughters and a son. Sullivan died on August 8, 1982.[5] He is buried inArlington National Cemetery.[6]
The house that Sullivan and his wife lived in, constructed in 1932–1933 in Manchester, New Hampshire, was added to theNational Register of Historic Places in July 2023.[7][8]
the oath of office of Assistant Secretary of the Navy for Air was administered to John L. Sullivan on board Shangri-La, the first ceremony of its type ever undertaken in a combat zone
