Duncan Brown Cooper
He was born at "Mulberry Hill" near Columbia in Maury County, Tennessee in 1844. His father was Matthew Delamere Cooper (1792-1878) and his mother, Marian Witherspoon (Brown) Cooper (1822-1861), who was his father's third wife. His half-brother was Judge William Frierson Cooper (1820–1909), a member of the Tennessee Supreme Court who owned the Riverwood Mansion. His sister Sarah married Dr. Lucius Burch, a Dean of the Vanderbilt University School of Medicine. Their son, Lucius E. Burch, Jr., was his nephew. He attended Jefferson College in Canonsburg, Pennsylvania, now known as Washington & Jefferson College.
After the war, he was elected a Democratic state congressman in 1881 and senator in 1895. He was also the publisher of the Nashville American, a conservative Democratic daily newspaper. He worked on the gubernatorial of Malcolm R. Patterson, who went on to serve as Governor of Tennessee from 1907 to 1911. Both Cooper and Patterson were opposed to prohibition. His gubernatorial opponent, Edward W. Carmack, who was the editor of The Tennessean, grew embittered and published scathing articles about Cooper.
On November 9, 1908, Cooper and his son Robin encountered Carmack on a Nashville street. Carmack fired first on the father and son, wounding the son. He retaliated, killing Carmack. Some accounts suggested it was premeditated murder. During the first trial, both Cooper and his son Robin were convicted of second-degree murder and twenty years in prison. Governor Patterson granted a pardon to Cooper and saved him from jail. Shortly after, Robin was granted a second trial and released. However, he was still vilified in the temperance press and shunned by Nashvillians. The pardoning of Cooper ultimately doomed the political career of Governor Patterson.
In 1865, he married his first wife, Florence Fleming (1843-1870), and they had three children. In the 1870s, he married his second wife, Mary Polk Jones (1856-1893), and they had five children. He inherited Riverwood from his brother's death in 1909 to his own in 1922. He was buried in the cemetery of Zion Presbyterian Church in Columbia, Tennessee.
