Clyde Cowan

Born the oldest of four children in Detroit, Michigan, Cowan's family moved to St. Louis, Missouri, where he began his education attending public schools. While attending the Missouri School of Mines and Metallurgy in Rolla, Missouri, Cowan was Editor-in-Chief of the Missouri Miner newspaper from 1939–1940, and graduated in 1940 with a BS in chemical engineering. ==Military career==

Cowan was a captain in the United States Army Air Forces, where he earned a bronze star in World War II. From 1936–1940 he was in the Reserve Officers' Training Corps. Cowan joined the U.S. Army Chemical Warfare Service with the rank of Second Lieutenant when America joined World War II in 1941. In August 1942, he was transferred to Eighth Air Force stationed in London, England. In 1943 he designed and built an experimental cleaning unit to be used in case of gas attack. In the following year, he joined the staff of the British Branch of the MIT Radiation Laboratory, which was located in Great Malvern, England. In 1945 he was a liaison officer with the Royal Air Force, working to expedite transmittal of technical information and equipment. He returned to the United States in 1945, and worked at Wright Patterson Air Force Base in Dayton, Ohio. He left active duty in 1946. ==Academic career==

Benefitting from the G.I. Bill, Cowan attended Washington University in St. Louis, Missouri, receiving a master's degree, and a PhD in 1949. He then joined the staff of the Los Alamos Scientific Laboratory in New Mexico, where he met Frederick Reines. In 1951 Reines and Cowan began the Cowan–Reines neutrino experiment, in hopes of discovering the neutrino. Because the neutrino was hypothetically created through beta decay, the two men made use of the Savannah River Plant in Aiken, South Carolina, as their source of potential neutrinos. The pair, and their collaborators, collected data for months, and in 1956, concluded that they had certainly observed the neutrino, publishing their work in the July 20, 1956 issue of Science. and was buried in Arlington National Cemetery. ==Family==

Cowan was married in Woodford, England, January 29, 1943 to Betty Eleanor, daughter of George Henry and Mabel Jane (Mather) Dunham of Wanstead, England. Seven of their children died in infancy. They had three surviving children. Cowan adopted two sons. His grandson, , a science journalist and a former physicist and engineer who heads the American Physical Society media relations office, initially conceived of the distributed computing project Einstein@home, which searches gravitational wave data for signals from massive rotating objects such as pulsars. Cowan was a direct descendant of L. L. Langstroth, the "Father of Modern Beekeeping". He was a devout Catholic and was a member of the Knights of Columbus. ==References==
