Francis Stuart Low (August 15, 1894 – January 22, 1964) was a decorated officer of the United States Navy with the rank of four-star Admiral. An expert in submarine warfare, Low is credited with the idea that twin-engined Army bombers could be launched from an aircraft carrier. This idea was later adopted for the planning of the Doolittle Raid. Low distinguished himself as Chief of Staff, U.S. Tenth Fleet during the U-boat campaign in the Atlantic Ocean and completed his career in 1956 as Commander, Western Sea Frontier, and Commander Pacific Reserve Fleet.
