Rockefeller was Lincoln Center's first president in 1956. He became its chairman in 1961. Rockefeller is credited with raising more than half of the $184.5 million in private funds needed to build the complex. The center's three buildings, Avery Fisher Hall (formerly Philharmonic Hall), David H. Koch Theater (formerly the New York State Theater) and the Metropolitan Opera House were opened in 1962, 1964 and 1966, respectively.
