Rockefeller Center, developed by John D. Rockefeller Jr.

John D. Rockefeller Jr. financed and developed Rockefeller Center in Midtown Manhattan during the 1930s; the complex's principal building is 30 Rockefeller Plaza. The site includes Radio City Music Hall and the building historically known as the RCA Building (now the Comcast Building) and was completed as a large commercial and cultural complex during the Great Depression. Rockefeller Center is documented as closely associated with Rockefeller Jr.'s role in urban development and philanthropy.
