the old Lake Success offices. The Secretariat Building's cafeteria opened in January 1952, and the fountain outside the building was dedicated in June 1952. The Secretariat Building finally began receiving visitors that year, after the rest of the UN complex opened. By the end of 1952, the complex received about 1,500 visitors per day. Workers cleaned the building for the first time in April 1953, and repairs to the facade were completed by that September. UN expansion The UN's membership expanded during the 1950s, prompting officials to expand the building's communications equipment in 1958. The next year, Secretary-General Dag Hammarskjöld proposed allocating US$635,000 to install automatic elevators in the Secretariat Building due to increasing labor costs. At that time, the building received about 2,500 to 3,000 tourists a day. By 1962, the Secretariat Building was occupied by 3,000 Secretariat employees (three quarters of the total staff), as well as other UN organizations. That year Secretary-General U Thant proposed constructing a two-story annex at a cost of US$6.3 million, but a UN committee rejected this proposal. A journalists' club in the building was opened the same year. In 1964, a UN panel approved a proposal to replace the elevators and renovate two of the building's unoccupied stories, but it rejected other proposals to expand the headquarters. Two years later, Thant proposed constructing another office building within the UN headquarters. By then, the Secretariat Building was nearing capacity, and some organizations such as UNICEF had been forced to relocate. The building's manual elevators were replaced by automatic cabs in 1967. Yet another expansion of the UN headquarters, including a park connected with the Secretariat Building, was proposed in 1968. This led to the construction of One United Nations Plaza, on 44th Street just outside the UN complex, in 1975. The main headquarters was expanded slightly from 1978 to 1981. As part of this project, a new cafeteria was built at the northern end of the headquarters, and the Secretariat Building's cafeteria had been converted into additional offices. Another office tower outside the headquarters proper, Two United Nations Plaza, was completed in 1983. By then, the Secretariat had over 6,000 employees, some of whom were forced to work within the United Nations Plaza towers. The new buildings were barely sufficient to accommodate the UN's demand for office space; the organization itself had expanded to 140 members by the 1970s. Furthermore, the Secretariat Building's
