About Harold Agnew

Harold Melvin Agnew (March 28, 1921 – September 29, 2013) was an American physicist, best known for having flown as a scientific observer on the Hiroshima bombing mission and, later, as the third director of the Los Alamos National Laboratory. Agnew joined the Metallurgical Laboratory at the University of Chicago in 1942, and helped build Chicago Pile-1, the world's first nuclear reactor. In 1943, he joined the Los Alamos Laboratory, where he worked with the Cockcroft–Walton generator. After the war ended, he returned to the University of Chicago, where he completed his graduate work under Enrico Fermi. Agnew returned to Los Alamos in 1949, and worked on the Castle Bravo nuclear test at Bikini Atoll in 1954. He became head of the Weapon Nuclear Engineering Division in 1964. He also served as a Democratic New Mexico State Senator from 1955 to 1961, and was the Scientific Adviser to the NATO Supreme Allied Commander Europe (SACEUR) from 1961 to 1964. He was director of the Los Alamos National Laboratory from 1970 to 1979, when he resigned to become President and Chief Executive Officer of General Atomics. He died at his home in Solana Beach, California, on September 29, 2013. He was a strong athlete who pitched for the university softball team that won a championship. Stearns, the head of the physics department at the University of Denver, persuaded Agnew to come with him to the University of Chicago, where Stearns became the deputy head of the Metallurgical Laboratory.
