Armistead Thomson Mason (August 4, 1787 – February 6, 1819),[1][2] the son of Stevens Thomson Mason,[1][2] was a U.S. Senator from Virginia from 1816 to 1817. Mason was also the second-youngest person to ever serve in the US Senate, at the age of 28 and 5 months, even though the age requirement for the US Senate in the constitution is 30 years old.[3]

Early life and education[edit]

He was born at Armisteads in Louisa County, Virginia, graduated from the College of William and Mary in 1807 and engaged in agricultural pursuits until he became colonel of Virginia Volunteers in the War of 1812 and subsequently brigadier general of Virginia Militia.

Political career[edit]

He was elected as a Republican to the United States Senate to fill the vacancy caused by the resignation of William Branch Giles, despite being constitutionally underage for the office. Mason served from January 3, 1816, to March 4, 1817. He then moved to Loudoun County, Virginia where he was an unsuccessful candidate for election to the Fifteenth Congress (1817). It was a bitter campaign that gave rise to several duels: Mason himself was later killed in a duel with his second cousin, John Mason McCarty, at Bladensburg Duelling Field, Maryland, as a result of this campaign. He is buried in the churchyard of the Episcopal Church at Leesburg, Virginia.[1][2]

Marriage and children[edit]

Mason married on 1 May 1817 to Charlotte Eliza Taylor (died 1846) at Dr. Charles Cocke's in Albemarle County, Virginia.[1][2] The couple had one son:[1][2]
