Camp David. National Archives. 2016-08-15 [2019-10-09]. (原始內容存檔於2020-05-03) (英語). Officially a U.S. Navy installation, the facility was originally built by the Works Progress Administration as a camp for government employees, opening in 1938. President Franklin D. Roosevelt took it over in a few years and named it "Shangri-La," for the mountain kingdom in Lost Horizon, the 1933 novel by James Hilton. It was renamed in 1953 by President Dwight D. Eisenhower in honor of his then-five-year-old grandson, Dwight David Eisenhower II.
