Biographical Note

Watchmaker, water-works builder, and businessman Caleb Leach (1755-1837) was born in Plymouth, Massachusetts, in 1755. As a young man, Leach was apprenticed to a watch maker. In July 1775, Caleb served for eight months in Captain James Keith’s company in the 28th regiment, commanded by Colonel Paul D. Sargent. He was discharged from the Army in 1780 having served in various different regiments during the Revolutionary War. Leach returned to Halifax, Massachusetts, as a clock/watch maker. In 1782, Caleb married Abigail Tinkham (died 1818); they had eight children: Ebenezer (1782-1796), Abigail (1785-1795), Caleb, Jr. (1786-), Ephraim (1788-1855), Samuel (1792-1838), Ebenezer (1797-1861), and Abigail (1802-1803).
In 1796, Leach, with Joshua Thomas and others, formed the Plymouth Aqueduct Company and constructed the Plymouth water works, said to have been the first water-works constructed in America. Leach was contracted to build the works, and he invented a screw auger and machine to bore out logs for its conduits. He patented his invention on April 13, 1979. In 1799, at the invitation of Aaron Burr, DeWitt Clinton and others, Leach built the Manhattan water works and later the first water works in Philadelphia and then Boston.
Around 1804, Leach, his youngest son Dr. Ebenezer Leach, and his brother Ephraim Leach, purchased a large tract of land in Owego, New York, where the family established Leach’s Mills, a grist and saw mill complex.
Following the death of his wife, Leach went to live with his son Ebenezer in Utica, New York, where he died in 1837 at the age of 82.
