Bacher then accepted the job at Los Alamos, moving there in May 1943 with his family to become the head of the Experimental Physics Division (P Division). His wife Jean Dow Bacher was also hired to work as a human computer in the Theoretical Division (T Division). For his seven group leaders he had John H. Williams, Robert R. Wilson, John H. Manley, Darol K. Froman, Emilio G. Segrè, Bruno B. Rossi and Donald W. Kerst. Bacher worked closely with Oppenheimer, and the two men discussed the project's progress on a daily basis.
