Many of the notable modern buildings in the postwar years were produced by two architectural mega-agencies, which brought together large teams of designers for very complex projects. The firm of [[Skidmore, Owings & Merrill]] was founded in Chicago in 1936 by [[Louis Skidmore]] and [[Nathaniel Owings]], and joined in 1939 by engineer [[John O. Merrill|John Merrill]], It soon went under the name of SOM. Its first big project was [[Oak Ridge National Laboratory]] in [[Oak Ridge, Tennessee]], the gigantic government installation that produced plutonium for the first nuclear weapons. In 1964 the firm had eighteen "partner-owners", 54 "associate participants, "and 750 architects, technicians, designers, decorators, and landscape architects. Their style was largely inspired by the work of [[Ludwig Mies van der Rohe]], and their buildings soon had a large place in the New York skyline, including the [[Manhattan House]] (1950–51), [[Lever House]] (1951–52) and the [[Manufacturers Trust Company Building]] (1954). Later buildings by the firm include [[Beinecke Library]] at [[Yale University]] (1963), the [[Willis Tower]], formerly Sears Tower in Chicago (1973) and [[One World Trade Center]] in New York City (2013), which replaced the building destroyed in the terrorist attack of 11 September 2001.{{Sfn|Bony|2012|pages=132–33}}

[[Wallace Harrison]] played a major part in the modern architectural history of New York; as the architectural advisor of the [[Rockefeller Family]], he helped design [[Rockefeller Center]], the major Art Deco architectural project of the 1930s. He was supervising architect for the 1939 New York World's Fair, and, with his partner [[Max Abramowitz]], was the builder and chief architect of the [[headquarters of the United Nations]]; Harrison headed a committee of international architects, which included [[Oscar Niemeyer]] (who produced the original plan approved by the committee) and [[Le Corbusier]]. Other landmark New York buildings designed by Harrison and his firm included [[Metropolitan Opera House (Lincoln Center)|Metropolitan Opera House]], the master plan for [[Lincoln Center]], and [[John F. Kennedy International Airport]].{{Sfn|Bony|2012|pages=132}}
