Arthur Levy was a member of the Special Engineering Detachment responsible for developing high explosive casting procedures for the Fat Man plutonium bomb at S-Site at Los Alamos. When the war ended, he attended the University of Minnesota, earning an M.S. in physical chemistry in 1948. Levy then went on to work for NASA's predecessor, the National Advisory Committee on Aeronautics (NACA) in Cleveland, Ohio from 1948 to 1949, Brookhaven National Laboratory from 1949 to 1951, and finally to Battelle Memorial Institute as a section manager and senior research leader from 1951 to 1985. His primary focus was in combustion kinetics and photochemical smog/air pollution chemistry. After leaving Battelle he worked as a consultant until 2004, mostly for the Ohio Coal Development Office.
