HistoryThis elegant home was constructed between 1919 and 1920 by architect William Adams Delano using the best available materials. It is said that the cost of construction equated to over one million dollars in 1920. In 1944, no one was living in the home, and as a result, the home was boarded up due to the Great Depression. On April 16, 1945, the home officially opened as the new headquarters for the Council on Foreign Relations, after it was donated to the Council.
