David McKendree Key
Key, David McKendree, 1824–1900, American politician and jurist, b. Greene co., Tenn. He practiced law in Chattanooga, Tenn., from 1853 to 1870, except during the Civil War, when he was an officer in the Confederate army. He served in the U.S. Senate (1875–77) to complete Andrew Johnson's term. In 1877, President Hayes chose Key to be his Postmaster General, an action that provoked sharp criticism from Republicans, who felt that the presence of an ex-Confederate in the cabinet violated party principles. From 1880 to 1894, Key served as U.S. judge for the eastern and middle districts of Tennessee.
