Although the International Telegraph Union was established in 1865, it was not until the second International Telegraph Conference in 1868 that a permanent central secretariat for the Union was established. Originally called the “Bureau international des Administrations télégraphiques,” the secretariat was placed under the direction of the Swiss government and was headed by a Director. Over the years, first a deputy director was added (1892) and then a deputy director dedicated to radiocommunication matters (1918). In 1947, the International Telecommunications Conference in Atlantic City decided to accept the invitation from the newly created United Nations for ITU to become the UN specialized agency for telecommunications. In conformity with UN practice, the Bureau was renamed the “General Secretariat,” and the title of “Director of the Bureau” was changed to “ITU Secretary-General.” In addition, the Atlantic City Conference made provisions for each of the International Consultative Committees for telephone, telegraph and radio (CCIF, CCIT, CCIR) to be headed by a director. Since 1992, ITU has been unique among the UN agencies in having 5 senior officials elected by its plenipotentiary conference: the Secretary-General, the Deputy Secretary-General, and the Directors of the Bureaux of the Radiocommunication Sector (BR), the Telecommunication Standardization Sector (TSB) and the Telecommunication Development Sector (BDT).
