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.
This collection contains the papers of American watchmaker and water-works builder
Caleb Leach (1755-1837). The majority of the collection deals with Leach’s invention, the screw auger, and his various business
ventures. There is also some material
related to Leach’s family into the beginning of the 20th century. The collection includes business records, correspondence
and other miscellaneous material.
The Business records include two account books, correspondence, receipts, bills, business contracts, documents dealing with
several of Leach’s projects
including the Manhattan Company, and the water-works in Plymouth, Boston and Philadelphia, indentures, and contracts with
manufacturers granting them
exclusive rights to produce the augers. Several of these documents contain details about the screw auger and how it works,
types of lumber used for the various projects, and the price of materials.
The Correspondence includes personal letters by various Leach, Tinkham, and Gale family members. There are also several postcards,
miscellaneous items, newspapers and clippings and empty envelopes.
