Thomas Jefferson Weygand (1800-1874) first learned the trade of a turner as a young man in Easton, Pennsylvania. He was fond of music and became a member of the “Artillerist Band,” organized in 1818 as part of the “Easton Artillerists.” Weygandt later moved to Philadelphia and made flutes and flageolets where he was active as a musical instrument maker from 1837 to 1870.
