At the conclusion of the two International Telecommunication Union (ITU) conferences held in Geneva in 1959—the Plenipotentiary (October 14 to December 16) and the Administrative Radio (August 17 to December 17)—two international documents were officially signed by the representatives of 85 and 84 countries respectively, namely: 1) the new Convention, replacing the International Telecommunication Convention of Buenos Aires, 1952; and 2) the new Radio Regulations, replacing those of Atlantic City, 1947. The Convention was to take effect on January 1, 1961, and the Radio Regulations on May i, 1961. Some additional protocols had to be signed as well, so that certain decisions (for example, the elections of the newly-constituted Administrative Council, the Secretary-General, and the Deputy Secretary-General, and changes made in the budget system) could take effect forthwith. Numerous recommendations and resolutions were also adopted, and decisions concerning the way ITU was organized, how it was run, and its future development were reached by the Plenipotentiary Conference, the chairman of which was Mr. J. D. H. van der Toorn, head of the Netherlands delegation. The chairman of the Radio Conference was Mr. Charles J. Acton, head of the Canadian delegation.
