Note: Abner Dod (1772 - 1847) came from a New Jersey family of skilled clock and watch makers, mathematical instrument makers and land surveyors. The father, Lebbeus Dod, had established an armory for the manufacture and repair of muskets during the Civil War. Three of the brothers - Abner, Daniel and S. Dod - are known to have made instruments, and Daniel went on to design an engine for the first transatlantic steamship, the Savannah.
