Construction of Rockefeller Center in the context of "Radio City Music Hall"

Wallace Kirkman Harrison (September 28, 1895 – December 2, 1981) was an American architect. Harrison started his professional career with the firm of Corbett, Harrison & MacMurray, participating in the construction of Rockefeller Center. He is best known for executing large public projects in New York City and upstate, many of them the fruit of his long friendship with governor Nelson Rockefeller.

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., the complex's developer. 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.

1211 Avenue of the Americas, also known as the News Corp. Building or the FOX Building, is an International Style skyscraper on Sixth Avenue in the Midtown Manhattan neighborhood of New York City. Formerly called the Celanese Building, it was completed in 1973 as part of the later Rockefeller Center expansion (1960s–1970s) dubbed the "XYZ Buildings". Celanese, its primary tenant, later moved to Dallas, Texas. The building is owned by Ivanhoé Cambridge as of 2023.

The structure has a simple slab-like shape devoid of any decoration, its prosaic façade consisting of vertical alternating limestone and glass stripes. The façade stone piers are supernumerary; there are twice as many of them as structurally necessary. The glass bands are contiguous and offer no indication of floor levels. These features ably create the visual lack of scale, so the tower does not look overly bulky.
