Samuel Slater (June 9, 1768 – April 21, 1835) was an early English-American industrialist known as the "Father of the American Industrial Revolution" (a phrase coined by Andrew Jackson) and the "Father of the American Factory System." In the UK he was called "Slater the Traitor" because he brought British textile technology to America, modifying it for United States use. He learned textile machinery as an apprentice to a pioneer in the British industry.
