Question: What WWII Fleet Admiral of the United States Navy was on the board of the American Cable and Radio Corporation? 
Context: Ellery Wheeler Stone, Rear Admiral, United States Naval Reserve (1894–1981) was a prominent figure in the history of radio, serving both in government and corporations during the first half of the twentieth century.  He studied radio engineering at the University of California.  In 1915-1916 he served as an assistant radio inspector for the United States Department of Commerce at San Francisco.  From 1917 to 1919 he was an officer in the United States Naval Reserve, and retained his reserve commission between the world wars.  He was president of the Federal Telegraph Company from 1924 to 1931, when ITT acquired the company together with the Mackay corporations.  Recalled to active duty in 1943 as a captain, he served from 10 November 1943 to July 1944 as Acting Chief Commissioner of the Allied Commission for Italy.  From July 1944 to 7 February 1947, he was the Chief Commissioner.  In 1947, at the conclusion of his military service, he became the head of the Commercial Cable Company, a subsidiary of the International Telephone and Telegraph corporation, and later oversaw its American Cable and Radio Corporation division until 1958.  He continued with ITT until his retirement in 1969, and at his death in 1981 was survived by a wife, Heide, and daughter, Marina. William Frederick Halsey Jr., GBE (October 30, 1882August 16, 1959), known as Bill Halsey or "Bull" Halsey, was an American admiral in the United States Navy during World War II.  He is one of the four individuals to have attained the rank of Fleet Admiral of the United States Navy. American Cable and Radio Corporation was a communications holding company in the middle 20th century.  Created in February 1940, it was a part of ITT World Communications, and operated what was known as the American Cable and Radio System, comprising All America Cables and Radio, the Commercial Cable Company, Mackay Radio, and the Sociedad Anonima Radio Argentina.  The company was created, along with the All America Corporation and the Commercial Mackay Corporation, after the reorganization of the ITT subsidiary Postal Telegraph and Cable Corporation, which had gone into bankruptcy in 1935.  The firm was active in the 1940s and 1950s.  Warren Lee Pierson, the wartime head of the Export-Import Bank, became the firm's president after the war.  Kenneth Evans Stockton was elected president in March 1948 and served until his death in 1950.  Famed admiral William Halsey Jr. was the chairman of the board after 1949.  Rear Admiral Ellery W. Stone, USN (retired), was president of the firm from 1950 to 1958.  Another prominent electrical engineer, Haraden Pratt, was vice president from 1953-1958.  The company was still in existence as late as 1980. The United States Fleet was an organization in the United States Navy from 1922 until after World War II.  The acronym CINCUS, pronounced "sink us", was used for Commander in Chief, United States Fleet.  This was replaced by COMINCH in December 1941, under , when it was redefined and given operational command over the Atlantic, Pacific, and Asiatic Fleets, as well as all naval coastal forces.  authorized the offices of the CNO and COMINCH to be held by a single officer; Admiral Ernest J. King was first to do so, and 1944 was promoted to the five-star rank of fleet admiral. This is a complete list of four-star admirals in the United States Navy.  The rank of admiral (or "full admiral", or "four-star admiral") is the highest rank normally achievable in the U.S. Navy.  It ranks above vice admiral ("three-star admiral") and below fleet admiral ("five-star admiral"). Admiral (abbreviated as ADM) is a four-star commissioned naval flag officer rank in the United States Navy, the United States Coast Guard, and the United States Public Health Service Commissioned Corps, with the pay grade of O-10.  Admiral ranks above vice admiral and below fleet admiral in the Navy; the Coast Guard and the Public Health Service do not have an established grade above admiral.  Admiral is equivalent to the rank of general in the other uniformed services.  The National Oceanic and Atmospheric Administration Commissioned Officer Corps has never had an officer hold the grade of admiral.  However,  /201 § 201  of the U.S. Code established the grade for the NOAA Corps, in case a position is created that merits the four-star grade. Marshal-admiral (元帥海軍大将 , gensui-kaigun-taishō ) was the highest rank in the prewar Imperial Japanese Navy.  The term "gensui" was used for both the navy and the Imperial Japanese Army, and was a largely honorific title awarded for extremely meritorious service to the Emperor.  In the Meiji period, the title was awarded to five generals and three admirals.  In the Taishō period it was awarded to six generals and six admirals, and in the Shōwa period it was awarded to six generals and four admirals.  Equivalent to a five-star rank (OF-10), it is similar to Admiral of the Fleet in the UK Royal Navy and fleet admiral in the United States Navy. Fleet admiral (abbreviated FADM), officially known as "Fleet Admiral of the United States Navy", is a five-star flag officer rank in the United States Navy.  Fleet admiral ranks immediately above admiral and is equivalent to General of the Army and General of the Air Force.  Although it is a current and authorized rank, no U.S. Navy officer presently holds it, with the last living U.S. Navy fleet admiral being Chester W. Nimitz, who died in 1966. The "Nimitz"-class supercarriers are a class of ten nuclear-powered aircraft carriers in service with the United States Navy.  The lead ship of the class is named after World War II United States Pacific Fleet commander Fleet Admiral Chester W. Nimitz, the U.S. Navy's last fleet admiral.  With an overall length of 1092 ft and full-load displacement of over 100,000 long tons, they have been the largest warships built and in service. The National Museum of the Pacific War is located in Fredericksburg, Texas, the boyhood home of Fleet Admiral Chester W. Nimitz.  Fleet Admiral Nimitz served as CinCPAC, Commander in Chief, United States Pacific Fleet during World War II.  The six acre site includes the Admiral Nimitz Museum which is housed in the old Nimitz Hotel and tells the story of Fleet Admiral Nimitz beginning with his life as a young boy through his naval career as well as the evolution of the old hotel.
