Who brought his knowledge of textile mills to the US

Samuel Slater, often referred to as the "Father of the American Industrial Revolution," brought his knowledge of textile mills to the United States. Slater was a skilled British mechanic who memorized the design of textile machinery and immigrated to the US in 1789. He partnered with Moses Brown, a wealthy merchant, and together they established the first successful water-powered cotton spinning mill in Pawtucket, Rhode Island, in 1793. Slater's knowledge and expertise in textile production played a significant role in jumpstarting the American industrial revolution and transforming the country into a leading industrial power.
