At SCOR's beginning, SCOR’s elected Secretary or President provided the necessary secretariat function. In 1972, a part-time Executive Secretary was appointed at the Royal Society (UK) to assist the elected Secretary. In 1985, as the scope and activities of SCOR had grown substantially, the Executive Secretary became a full-time employee; the title was changed to Executive Director in 1990. The Secretariat moved over the years from the Royal Society (UK) to Dalhousie University (Canada) in 1980, to Johns Hopkins University (USA) in 1992, and to the University of Delaware (USA) in 2007.
