Frederick "Fred" Moore Vinson (January 22, 1890 – September 8, 1953) was an American politician who served the United States in all three branches of government and was the most prominent member of the Vinson political family. In the legislative branch, he was an elected member of the United States House of Representatives from Louisa, Kentucky, for twelve years. In the executive branch, he was the Secretary of Treasury under President Harry S. Truman. In the judicial branch, President Truman appointed Vinson the 13th Chief Justice of the United States in 1946. To date, he is the last candidate nominated by a president from the Democratic Party to be confirmed as Chief Justice (Lyndon Johnson nominated Abe Fortas as Chief Justice in 1968, but Fortas later withdrew his name from consideration).
