the Department of War to the Department of the Army, Draper became the first under secretary of the Army from September 18, 1947, to February 28, 1949. Later in 1949, he rejoined Dillon Read as a senior partner. According to the Annenberg CPB documentary "The Pacific Century, Ep.5 Reinventing Japan" Gen. Draper, referred to therein as the "Wall Street General" was instrumental in overturning some key progressive reforms sought by Colonel Charles Kades of the Supreme Command Allied Powers (SCAP) in occupied Japan. Draper served as Long Island Rail Road trustee from 1950 to 1951. He served as the first US Ambassador to NATO in Paris. Hiss Case involvement On August 7, 1948, Draper, then Undersecretary of War, requested that William L. Marbury Jr. fly to Geneva, Switzerland, and spend a month there to help the U.S. negotiate the General Agreement on Tariffs and Trade (GATT). Marbury was a close friend of Alger Hiss. Draper's request came days after Whittaker Chambers had included Hiss's name among those of government spies in the Ware Group during Chambers' testimony under subpoena before the House Un-American Activities Committee (HUAC). In effect, the request prevented Marbury from helping during Hiss's further HUAC testimony in August and into September, when Hiss was considering a libel suit against Chambers for statements made August 27 on NBC Radio's nationwide Meet the Press broadcast. Later career After retiring from public service a second time, he traveled to in Mexico City to serve as chairman of the Mexican Light and Power Company. Returning to the U.S. in 1959, he formed the first West Coast venture capital firm Draper, Gaither and Anderson in California. In 1967, he retired from Draper Gaither, moved to Washington, D.C. and joined Combustion Engineering in New York as chairman, retiring a few years later to become the U.S. delegate to the United Nations Population Commission, serving from 1969 to 1971. He also cofounded the Population Crisis Committee in 1965 and chaired the Draper Committee.
