Thomas Knight Finletter (November 11, 1893 – April 24, 1980), was an American lawyer, politician, and statesman.
Finletter was born in Philadelphia, Pennsylvania, the son of Thomas Dickson Finletter and Helen Grill Finletter. He took his early education at The Episcopal Academy in Philadelphia and graduated from the University of Pennsylvania with both Bachelor of Arts degree in 1915 and bachelor of laws in 1920. He also served as editor-in-chief of the University of Pennsylvania Law Review. 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.
In the same year he was a cosigner of the “Declaration of the Dublin, N.H., Conference”, a declaration on world peace issued by the Dublin Conference on World Peace. The declaration stated that the United Nations was inadequate to maintain world peace, and advocated a world federal government.
