Richard Milhous Nixon was the 37th president of the United States, serving from 1969 until his resignation in 1974. A member of the Republican Party, he previously served as a representative and senator from California and as the 36th vice president from 1953 to 1961 under President Dwight D. Eisenhower. His presidency saw the reduction of U.S. involvement in the Vietnam War,
détente with the Soviet Union and China, the Apollo 11 Moon landing, and the establishment of the Environmental Protection Agency and Occupational Safety and Health Administration. Nixon's second term ended early when he became the only U.S. president to resign from office, as a result of the Watergate scandal.
