Researching William Parsons

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, an invention that was provided to US by the UK Tizard Mission, 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.

Originally a chorister at Westminster Abbey as a pupil of Benjamin Cooke, he developed a reputation as a fine tenor, but was passed over for another musician at the Royal Opera House, Covent Garden and thus went to Europe to seek employment. Returning to England, he was an assistant director at the George Frideric Handel commemorations in Westminster Abbey and the Pantheon in 1784, and composed a number of anthems for royal usage. He was an assistant director of the festival with many other prominent English composers at the time, such as Thomas Sanders Dupuis, Samuel Arnold, and his teacher, Benjamin Cooke. He gained a doctorate in music at Oxford University in 1790. In his spare time, he acted as a magistrate for the jurisdiction near his house in Portman Square.

He was knighted by the Lord Lieutenant of Ireland, John Jeffreys Pratt, second Earl Camden in 1795, thus becoming the first British musician honoured with a knighthood. An unremarkable composer and musician, he gained the title more through tutoring the king's family and his contacts than any merit, being a friend of several members of the royal family and composers such as Joseph Haydn. Few of his compositions survive.
