Rockefeller Center

Rockefeller Center is a complex of 19 commercial buildings covering 22 acres (8.9 ha) between 48th Street and 51st Street in the Midtown Manhattan neighborhood of New York City. The 14 original Art Deco buildings, commissioned by the Rockefeller family, span the area between Fifth Avenue and Sixth Avenue, split by a large sunken square and a private street called Rockefeller Plaza. Later additions include 75 Rockefeller Plaza across 51st Street at the north end of Rockefeller Plaza, and four International Style buildings on the west side of Sixth Avenue.

In 1928, Columbia University, the owner of the site, leased the land to John D. Rockefeller Jr., who was the main person behind the complex's construction. Originally envisioned as the site for a new Metropolitan Opera building, the current Rockefeller Center came about after the Met could not afford to move to the proposed new building. Various plans were discussed before the current one was approved in 1932. Construction of Rockefeller Center started in 1931, and the first buildings opened in 1933. The core of the complex was completed by 1939. Described as one of the greatest projects of the Great Depression era, Rockefeller Center became a New York City designated landmark in 1985 and a National Historic Landmark in 1987. The complex and associated land has been controlled since 2000 by Tishman Speyer, which bought the property for $1.85 billion.

The original center has several sections. Radio City, along Sixth Avenue and centered on 30 Rockefeller Plaza, includes Radio City Music Hall and was built for RCA's radio-related enterprises such as NBC. The International Complex along Fifth Avenue was built to house foreign-based tenants. The remainder of the original complex originally hosted printed media as well as Eastern Air Lines. While 600 Fifth Avenue is at the southeast corner of the complex, it was built by private interests in the 1950s and was only acquired by the center in 1963. The complex is noted for the large quantities of art present in almost all of its buildings, its expansive underground concourse, its ice-skating rink, and its annual lighting of the Rockefeller Center Christmas Tree.

The first private owner of the site was physician David Hosack, who purchased twenty acres of rural land from New York City in 1801 and opened the country's first public botanical garden, the Elgin Botanic Garden, on the site. The gardens operated until 1811, and by 1823 the property was under the ownership of Columbia University. Columbia held the property as an investment, and by 1896 consolidated its main campus 60 blocks north in Morningside Heights, in Upper Manhattan

In 1926, the Metropolitan Opera started looking for locations for a new opera house to replace the existing building at 39th Street and Broadway. By 1928, Benjamin Wistar Morris and designer Joseph Urban were hired to come up with blueprints for the house. However, the new building was too expensive for the Met to fund by itself, and John D. Rockefeller Jr. eventually gave his support to the project (John D. Rockefeller Sr., his father, was not involved). Rockefeller hired Todd, Robertson and Todd as design consultants to determine its viability. John R. Todd then put forth a plan for the Met. Columbia leased the plot to Rockefeller for 87 years at a cost of $3 million per year, excluding some properties on Fifth Avenue and a strip on Sixth Avenue. The initial cost of acquiring the space, razing some of the existing buildings, and constructing new buildings was estimated at $250 million.

Rockefeller hired Corbett, Harrison & MacMurray; Hood, Godley & Fouilhoux; and Reinhard & Hofmeister, to design the buildings. They worked under the umbrella of "Associated Architects" so none of the buildings could be attributed to any specific firm. The principal builder and "managing agent" was John R. Todd, one of the co-founders of Todd, Robertson and Todd. The principal architect and leader of the Associated Architects was Raymond Hood, a student of the Art Deco architectural movement. The other architects included Harvey Wiley Corbett and Wallace Harrison. L. Andrew Reinhard and Henry Hofmeister had been hired by John Todd as the "rental architects", who designed the floor plans for the complex. The Metropolitan Square Corporation (the precursor to Rockefeller Center Inc.) was formed in December 1928 to oversee construction.

After the stock market crash of 1929, the Metropolitan Opera could not afford to move anymore. After the opera plans were canceled on December 6, 1929, Rockefeller quickly negotiated with Radio Corporation of America (RCA) and its subsidiaries, National Broadcasting Company (NBC) and Radio-Keith-Orpheum (RKO), to build a mass media entertainment complex on the site. By May 1930, RCA and its affiliates had agreed to develop the site. Todd released a new plan "G-3" in January 1930, followed by an "H plan" that March. Another plan, announced in March 1931, received mostly negative feedback from the public. The design of the complex was affected greatly by the 1916 Zoning Resolution, which required setbacks to all high street-side exterior walls of New York City buildings in order to increase sunlight for city streets. The plan also included rooftop gardens and a recessed central plaza. The International Complex, announced in 1931, replaced an earlier plan for an oval retail building; its name was derived by the British, French, and Italian tenants who eventually occupied it.

During early planning, the development was often referred to as "Radio City", "Rockefeller City", or "Metropolitan Square" (after the Metropolitan Square Corporation). Ivy Lee, the Rockefeller family's publicity adviser, suggested changing the name to "Rockefeller Center". John Rockefeller Jr. initially did not want the Rockefeller family name associated with the commercial project, but was persuaded on the grounds that the name would attract far more tenants. The name was formally changed in December 1931. Over time, the appellation of "Radio City" devolved from describing the entire complex to just the complex's western section, and by 1937, only the Radio City Music Hall contained the "Radio City" name.
