Robert Ellingson arrived in Oak Ridge in June 1943. Shortly after Ellingson arrived, however, he was informed by his employer, Tennessee Eastman, that they already had too many chemists and chemical engineers.
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.
