The Rockefeller family moved into various floors and suites throughout the same building to give potential tenants the impression of occupancy. In particular, the family's office took up "Room 5600" on the entire 56th floor, while the family's Rockefeller Foundation took up the entire floor below, and two other organizations supported by the Rockefellers also moved into the building. By 1937, there were 392 employees of Room 5600, and by the time World War II was over, Room 5600 comprised the entire 54th through 56th floors. The family offices became a hub for the family's political activity, with ties to both the Democratic and Republican parties at the city, state, and national levels. Frank Sinatra, Shirley MacLaine, Nelson Mandela, Richard Gere, and Bono all came to the offices at one time or another. The family moved out in 2014, and this space is now occupied by Rockefeller Family and Associates, whose offices span the 54th to 56th floors. John D. Rockefeller had a private vault in the basement of the building, accessible via a private elevator from his office.
