Harry Kamack worked as a chemical engineer for the DuPont Company during the early 1940s, when he was transferred to Chicago to work at the Metallurgical Laboratory. As a chemical engineer, Kamack admits that he did not have much knowledge of nuclear physics, but he quickly learned and was soon tasked with building a Geiger counter. In 1943, Kamack was transferred to Oak Ridge, where he continued work on developing processes for the separation of plutonium at the X-10 Graphite Reactor. In October of 1944, Kamack was transferred again to Hanford, where he continued research on the chemical separations process of the T-Plant.
