John Brady served as a Machinist at the Hanford Nuclear Reservation from 1943 to 1960. He was proud of the work he did at Hanford, though it was always a mystery to his children because Brady wouldn't talk about his job.
Eric Jette (1897-1963) was an American metallurgist. He was a professor of metallurgy at Columbia University School of Mines before being recruited for the Manhattan Project.
