Samuel SlaterDied 21 Apr 1835 at age 66 (born 9 Jun 1768).English-American mechanical engineer who founded the American cotton-textile industry. Before he left Nottingham and immigrating to the U.S. in 1789, Slater apprenticed with Jedediah Strutt (partner of Richard Arkwright) in England. Once in the U.S., he found backing to build Arkwright's spinning and carding machinery, with which he established the first successful cotton mill in the U.S. in Pawtucket, Rhode Island, as well as many others in the New England region. |
