The hotel played a considerable role in the emerging Cold War and international relations during the postwar years, staging numerous events and conferences. On March 15, 1946, Winston Churchill attended a welcoming dinner at the hotel given by Governor Thomas E. Dewey, 10 days after making his famous Iron Curtain speech, and from November 4 to December 12, 1946, the Big Four Conference was held in Jørgine Boomer's apartment on the 37th floor of the Towers between the United States, Britain, France, and the Soviet Union to discuss the future of Eastern Europe. On November 24, 1947, 48 prominent figures of the Hollywood film industry, including various film executives such as Louis B. Mayer of Metro-Goldwyn-Mayer, Harry Cohn of Columbia Pictures, Spyros Skouras of 20th Century Fox, Albert Warner of Warner Bros., and Eric Johnston, the head of the Association of Motion Picture Producers, met at the Waldorf Astoria and discussed what would become the Waldorf Statement, banning people with Communist beliefs or tendencies from the Hollywood film industry. The statement was a response to the contempt of Congress charges against the so-called "Hollywood Ten".
