Stanley Stewart was the Contracting Officer at Los Alamos during the Manhattan Project. After the bombings of Hiroshima and Nagasaki, Stewart wrote, “The security restrictions on our part of the work [at Los Alamos] have been more rigid than than on any other portion of the entire Manhattan Project. Loose talk and speculation, particularly by individuals now or formerly connected with the project, jeopardize the future of the nation and must be controlled.”
