The Rockefeller Center

From Wikipedia's website:

Rockefeller Center was named after John D. Rockefeller Jr. ("Junior"), who leased the space from Columbia University in 1928 and developed it from 1930. Rockefeller initially planned a syndicate to build an opera house for the Metropolitan Opera Company on the site, but changed his mind after the stock market crash of 1929 and the withdrawal of the Metropolitan from the project. He took on the enormous project as the sole financier, on a ninety-nine-year lease for the site from Columbia; negotiating a line of credit with the Metropolitan Life Insurance Company and covering ongoing expenses through the sale of oil company stock.

It was the largest private building project ever undertaken in modern times. Construction of the 14 buildings in the Art Deco style (without the original opera house proposal) began on May 17, 1930 and was completed on November 1, 1939 when he drove in the final (silver) rivet into 10 Rockefeller Plaza. Principal builder, and "managing agent", for the massive project was John R. Todd and principal architect was Raymond Hood, working with and leading three architectural firms, on a team that included a young Wallace Harrison, later to become the family's principal architect and adviser to Nelson Rockefeller.

It was the public relations pioneer Ivy Lee, the prominent adviser to the family, who first suggested the name "Rockefeller Center" for the complex, in 1931. Junior initially didn't want the Rockefeller family name associated with the commercial project, but was persuaded on the grounds that the name would attract far more tenants.

What could have become a major controversy in the mid-1930s concerned the last of the four European buildings that remained unnamed. Attempts were made by Ivy Lee and others to rent out the space to German commercial concerns and name it the Deutsches Haus. Junior ruled this out after being advised of Hitler's Nazi march towards World War II, and thus the empty office site became the International Building North.

This subsequently became the primary location of the US operations of British Intelligence (MI6) during the War, with Room 3603 becoming the principal operations center for US intelligence, organised by William Joseph Donovan, as well as the office of the future head of what was later to become the Central Intelligence Agency, Allen Dulles.

The Center is a combination of two building complexes: the older and original 14 Art Deco office buildings from the 1930s, and a set of four International-style towers built along the Avenue of the Americas during the 1960s and 1970s (plus the Lehman Brothers Building). (The Time-Life Building, McGraw Hill and News Corporation/Fox News Channel headquarters are part of these "newer" Rockefeller Center buildings, which are now owned/managed by the major private real estate firm, Rockefeller Group.)

The entire Rockefeller Center complex was purchased by Mitsubishi Estate, a real estate company of the Mitsubishi Group, in 1989, which fully bought out Rockefeller Group. In 2000, the current owner Jerry Speyer (a close friend of David Rockefeller), of Tishman Speyer Properties, L.P., together with the Lester Crown family of Chicago, bought for $1.85 billion the older 14 buildings and land from the previous syndicated owners: Goldman Sachs (which had 50 percent ownership), Giovanni Agnelli, Stavros Niarchos, and David Rockefeller, who organized the syndicate in 1996 and is historically associated with the other partners.
