William C. “Bill” Elmore was an American experimental physicist who served as the chairman of the Physics department at Swarthmore College from 1948 to 1968.
After finishing his Ph.D. from Yale University in 1935, Elmore was one of many young physicists recruited to work at Los Alamos. There, he helped design electronic bomb triggers, working alongside future Nobel Prize winner Val Fitch.
While working on the Manhattan Project, Elmore became friends with another experimental physicist, Matthew Sands. The two would collaborate after the war to write the foundational physics textbook Electronics: Experimental Techniques in 1949.
