founder of the American cotton- textile industry.

As an apprentice in England to Jedediah Strutt (partner of Richard Arkwright), Slater gained a thorough knowledge of cotton manufacturing. He immigrated to the United States in 1789, attracted by the bounties offered there for workers skilled in the manufacturing of cotton. He was forced to keep his knowledge and skills a secret from authorities, however, because at the time emigration of textile workers and the export of drawings of textile machinery were forbidden by British law. With his detailed knowledge of textile machinery, financial backing from the Rhode Island firm of Almy and Brown, and the assistance of skilled artisans, he constructed versions of Arkwright's spinning and carding machinery and established the first successful cotton mill in the United States (Pawtucket, R.I., 1793). He subsequently established a number of other plants in New England and founded the town of Slatersville, R.I.
