The papers of Seymour Weiss document his long career as an analyst at the U.S. Department of State. Working closely with his
counterparts in the Department of Defense, Weiss specialized in the fields of nuclear strategy and arms control. The bulk
of his papers consist of correspondence, memoranda, photographs, and reports, among which are numerous studies of the strength
of the Soviet military and analyses of treaties such as the Strategic Arms Limitation Treaties (SALT I and II).
