The Secretary-General

The Secretary-General was envisioned by US President Franklin D. Roosevelt as a "world moderator," but the office was defined in the UN Charter as the organization's "chief administrative officer" (Article 97). Nevertheless, this more restricted description has not prevented the office holders from speaking out and playing important roles on global issues, to various degrees.

The official residence of the Secretary-General is a five-story townhouse in the Sutton Place neighborhood of Manhattan in New York City, New York, United States. The townhouse was built for Anne Morgan in 1921, and donated to the United Nations in 1972.
