Sterling Iron Works
Mr. Peter Townsend, who became the owner of Sterling Iron before the Revolutionary War, made iron anchors in 1773, and in 1776 produced the first steel in New York, at first from pig and afterward from bar iron. The first blister steel made in the State was made by his son, Peter Townsend, Jr., in 1810, from ore of the Long Mine on the Sterling estate. In the manufacture of edge-tools it was considered equal to the famous Dannemora mine Swedish Iron.
