In World War I, he served with the 312th Field Artillery advancing to the rank of captain. He was admitted to the Pennsylvania bar in 1920 and the New York Bar in 1921.
Finletter practiced law in New York until he began his government service in 1941, as a special assistant to Secretary of State Cordell Hull on international economic affairs. In 1943, he was appointed executive director and later deputy director of the Office of Foreign Economic Coordinator (OFEC). In this post, he was in charge of planning economic activities related to liberated areas and was in control of matters of foreign exchange and matters relating to the operations of the Alien Property Custodian. Finletter resigned his post in 1944, when the functions of OFEC were absorbed by the newly created Foreign Economic Administration.
In 1945, Finletter acted as consultant at the United Nations Conference on International Organization at San Francisco.
He returned back to public service July 18, 1947, when President Harry S. Truman established a temporary, five-man commission that inquired into all phases of aviation and drafted the national air policy report. This commission was sometimes known as "The Finletter Commission". Finletter served as chairman of the Air Policy Commission which, on January 1, 1948, sent to the president the report entitled "Survival in the Air Age."
Finletter was chief of the Economic Cooperation Administration's mission to the United Kingdom with headquarters in London, to which he had been appointed early in 1949.
Secretary of the Air Force
President Truman appointed Finletter as the second Secretary of the Air Force succeeding Stuart Symington on April 24, 1950, in which office he served until January 20, 1953.
In 1958, Finletter was a candidate for the Democratic nomination for the U.S. Senate from New York. He won the support of some liberal reformers, prominently including Eleanor Roosevelt,[2] and was chosen as the Liberal Party's candidate, though the Democratic Convention preferred Frank Hogan. Finletter then withdrew from the Liberal ticket, endorsing Hogan.[3]
In 1965, following his term as Ambassador to NATO, he retired from government service and returned to his law practice with the firm of Coudert Brothers, in New York City. In January 1967, he approached Senator Eugene McCarthy to see if he was interested in challenging Lyndon Johnson for the 1968 Democratic nomination for president, on the issue of the Vietnam War.[4] McCarthy did go on to challenge Johnson, but failed to win the Democratic nomination. Finletter died on April 24, 1980.
