Robert Mercer Taliaferro Hunter

Robert Mercer Taliaferro Hunter (April 21, 1809 – July 18, 1887) was a Virginia lawyer, politician and plantation owner. He was a U.S. Representative (1837–1843, 1845–1847), Speaker of the House (1839–1841), and U.S. Senator (1847–1861). During the American Civil War, Hunter became the Confederate States Secretary of State (1861–1862) and then a Confederate Senator (1862–1865) and critic of President Jefferson Davis. After the war, Hunter failed to win re-election to the U.S. Senate, but did serve as the Treasurer of Virginia (1874–1880) before retiring to his farm. After fellow Democrat Grover Cleveland was elected President of the United States in 1884, Hunter became the customs collector for the port of Tappahannock until his death.
