Administrative history

Created on 1 January 1971, the series EXS contains the memoranda of the Executive Secretary(1). The Executive Secretary, under the direction of the Secretary General and the Deputy Secretary General, directed the work of the Office of the Secretary General and coordinated the general activity of the International Staff; he acted as Secretary of the Council and was responsible to the Secretary General for programming its work and for seeing that actions were initiated on decisions of the Council. He was responsible for supervising secretaries of the committees of the Council. On those aspects of the work of the Organization which were not the direct responsibility of one Assistant Secretary General, the Executive Secretary maintained liaison with delegations at the appropriate level and with the Office of the Standing Group Liaison Officer.In 1956, a reorganisation of the Executive Secretariat led to the transfer of responsibilities of personnel management, conference services and recruitment, which came under the direction of a new Director of Administration. From 1957 to 1967, the Executive Secretariat was given the responsibility of supervising civil emergency planning and between 1966 and 1970 it was also in charge of crisis management and communications.The post of Executive Secretary disappeared with the restructuring of the International Staff in 2003 and the establishment of the Council Secretariat within the newly created Executive Management Division(2). Executive Secretaries for the period 1971-2003 were as follows:Mr. Kurt W. Andreae (1970-1973), Mr. George E. Sekeris (1973-1978), Mr. Tugay Ozceri (1979-1988), Mr. Christopher Prebensen (1988-1993) and Mr. Leo Verbruggen (1993-2003).
