Slater family.

Samuel Slater (1768-1835), the founder of the American cotton industry, emigrated from England in 1789, having memorized the plans for a cotton mill. He opened his first factory in Pawtucket, R.I., in 1793, and Slater and his family later expanded their woolen and cotton mills throughout Rhode Island and central Massachusetts. His son, Horatio Nelson Slater (1808-1888), eventually inherited much of the Slater and Sons business in Webster and Oxford, Mass.
