Adamson Tannehill (1750–1820) was an American military officer, politician, civic leader, and farmer. Born in Maryland, Tannehill was among the first to join the Continental Army during the American Revolutionary War, becoming commander of the Maryland and Virginia Rifle Regiment. He then settled in Pittsburgh, Pennsylvania, where he was active in the state militia, rising to the rank of major general in 1811. He also served as a brigadier general of United States Volunteers in the War of 1812. Tannehill held several local, state, and national offices, including one term as a Democratic-Republican in the U.S. House of Representatives from 1813 to 1815. He was president of the Pittsburgh branch of the Bank of the United States from 1817 until his death. He also served on the founding boards of several civic and state organizations. Tannehill died in 1820 and was buried at his Grove Hill home outside Pittsburgh. He was later reinterred in Allegheny Cemetery (gravestone pictured). (Full article...)
