In the mid 1930s The Rockefeller Group had unnamed buildings. One of the unnamed was The International Building. Attempts were made to rent out the space to German commercial concerns and name it the Deutsches Haus. This was ruled out due to Hitler's Nazi march towards World War II. The empty office site became the International Building North. This building became the primary location of the US operations of British Intelligence during the War. The chief architect of the massive 19 building project, including the Simon and Schuster Building, was Raymond Hood.
