Rex Edward Keller was a member of the Special Engineering Detachment, assigned to work in Seth Neddermeyer'schemistry group at Los Alamos. Keller arrived at Los Alamos in July 1943, primarily to assist in the experimental work of Neddermeyer and his colleague, Joseph Kennedy. Given the difficulties of the implosion design, Keller feared that it would not work until witnessing the Trinity test in July 1945.
