The eldest son of Benjamin Tupper, Anselm enlisted in the fight for independence during 1775, while only eleven years old, achieving the rank of lieutenant before his seventeenth birthday. After the war, he was a pioneer and surveyor in the Northwest Territory, and became major of the militia at Marietta during the Northwest Indian War. Tupper was the first school teacher at Marietta, and was a classical scholar and poet. He was unmarried, and was known as a favorite in society.
