Rear Admiral William Sterling "Deak" Parsons (26 November 1901 – 5 December 1953) was an American naval officer who worked as an ordnance expert on the Manhattan Project during World War II. He is best known for being the weaponeer on the ''Enola Gay'', the aircraft which dropped the Little Boy atomic bomb on Hiroshima, Japan in 1945. During the flight to Hiroshima, Parsons climbed into the bomb bay to load the powder charge, to avoid the possibility of a nuclear explosion if the aircraft crashed and burned on takeoff. He was awarded the Silver Star for his part in the mission. A 1922 graduate of the United States Naval Academy, Parsons served on a variety of warships beginning with the battleship . He was trained in ordnance and studied ballistics under L.T.E. Thompson at the Naval Proving Ground in Dahlgren, Virginia. In July 1933, Parsons became liaison officer between the Bureau of Ordnance and the Naval Research Laboratory. He became interested in radar and was one of the first to recognize its potential to locate ships and aircraft, and perhaps even track shells in flight. In September 1940, Parsons and Merle Tuve of the National Defense Research Committee began work on the development of the proximity fuze, a radar-triggered fuze that would explode a shell in the proximity of the target. The fuze, eventually known as the VT (variable time) fuze, Mark 32, went into production in 1942. Parsons was on hand to watch the cruiser shoot down the first enemy aircraft with a VT fuze in the Solomon Islands in January 1943. In June 1943, Parsons joined the Manhattan Project as Associate Director at the research laboratory at Los Alamos, New Mexico under J. Robert Oppenheimer. Parsons became responsible for the ordnance aspects of the project, including the design and testing of the non-nuclear components of nuclear weapons. In a reorganization in 1944, he lost responsibility for the implosion-type fission weapon, but retained that for the design and development of the gun-type fission weapon, which eventually became Little Boy. He was also responsible for the delivery program, codenamed Project Alberta. He watched the Trinity nuclear test from a B-29. After the war, Parsons was promoted to the rank of rear admiral without ever having commanded a ship. He participated in Operation Crossroads, the nuclear weapon tests at Bikini Atoll in 1946, and later the Operation Sandstone tests at Enewetak Atoll in 1948. In 1947, he became deputy commander of the Armed Forces Special Weapons Project. He died of a heart attack on 5 December 1953. == Early life == William Sterling Parsons was born in Chicago, Illinois, on 26 November 1901, the oldest of three children of a lawyer, Harry Robert Parsons, and his wife Clara, née Doolittle. In 1909, the family moved to Fort Sumner, New Mexico, where William learned to speak fluent Spanish. He attended the local schools in Fort Sumner and was home schooled by his mother for a time. He commenced at Santa Rosa High School, where his mother taught English and Spanish, rapidly advancing through three years in just one. In 1917 he attended Fort Sumner High School, from which he graduated in 1918. In 1917 Parsons travelled to Roswell, New Mexico to take the United States Naval Academy exam for one of the appointments by Senator Andrieus A. Jones. He was only an alternate, but passed the exam while more favored candidates did not, and received the appointment. As he was only 16, two years younger than most candidates, he was shorter and lighter than the physical standards called for, but managed to convince the examining board to admit him anyway. He entered the Naval Academy at Annapolis, Maryland in 1918, and eventually graduated 48th out of 539 in the class of 1922, in which Hyman G. Rickover graduated 107th. At the time, it was customary for midshipmen to acquire nicknames, and Parsons was called "Deacon", a play on his last name. This became shortened to "Deak". 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「William Sterling Parsons」の詳細全文を読む スポンサード リンク
