at nearby
Cromford Mill. In 1782, his father died, and his family indentured Samuel as an apprentice to Strutt. Slater was well trained by Strutt and, by age 21, he had gained a thorough knowledge of the organization and practice of cotton spinning.
He learned of the American interest in developing similar machines, and he was also aware of British law against exporting the designs. He therefore memorized as much as he could and departed for New York in 1789. Some people of Belper called him "Slater the Traitor", as they considered his move a betrayal of the town where many earned their living at Strutt's mills.

Moses Brown moved to
Pawtucket, Rhode Island to operate a mill in partnership with his son-in-law William Almy and cousin Smith-Brown.

pattern" but could not operate it. At this point, Slater wrote to them, offering his services. Slater realized that nothing could be done with the machinery as it stood and convinced Brown of his knowledge. He promised: "If I do not make a good yarn, as they do in England, I will have nothing for my services but will throw the whole of what I have attempted over the bridge." In 1790, he signed a contract with Brown to replicate the British designs. Their deal provided Slater the funds to build the water frames and associated machinery, with a half share in their capital value and the profits derived from them. By December, the shop was operational with ten to twelve workers. By 1791, Slater had some machinery in operation, despite shortages of tools and skilled mechanics. In 1793, Slater and Brown
opened their first factory in Pawtucket.
Slater knew the secret of Arkwright's success—namely, that account had to be taken of varying fiber lengths—but he also understood Arkwright's carding, drawing, and roving machines. He also had the experience of working with all the elements as a continuous production system. During construction, Slater made some adjustments to the designs to fit local needs. The result was the first successful
water-powered roller spinning textile mill in America.
After developing this mill, Slater instituted management principles that he had learned from Strutt and Arkwright to teach workers to be skilled mechanics.
In 1812, Slater built the Old Green Mill, later known as Cranston Print Works, in East Village in Webster, Massachusetts. He moved to Webster due in part to an available workforce, but also due to abundant water power from Webster Lake.
Management style

Slater created the "Rhode Island System", factory practices based upon family life patterns in New England villages. Children aged 7 to 12 were the first employees of the mill; Slater personally supervised them closely. The first child workers were hired in 1790.
He brought in whole families, developing entire villages. He provided company-owned housing nearby, along with company stores; he sponsored a Sunday School where college students taught the children reading and writing.
Expansion
Slater constructed a new mill in 1793 for the sole purpose of textile manufacture under Almy, Brown & Slater, as he was now partners with Almy and Brown. It was a 72-spindle mill; the patenting of

In 1798, Samuel Slater split from Almy and Brown, forming Samuel Slater & Company in partnership with his father-in-law Oziel Wilkinson. They developed other mills in Rhode Island, Massachusetts, Connecticut, and New Hampshire.

Samuel put John Slater in charge of a large mill called the White Mill.
By 1810, Slater held part ownership in three factories in Massachusetts and Rhode Island. In 1823, he bought a mill in Connecticut. He also built factories to make the textile
manufacturing machinery used by many of the region's mills and formed a partnership with his brother-in-law to produce iron for use in machinery construction. But Slater spread himself too thin and was unable to coordinate or integrate his many different business interests. He refused to go outside his family to hire managers, and, after 1829, he made his sons partners in the new umbrella firm of Samuel Slater and Sons. His son Horatio Nelson Slater completely reorganized the family business, introduced cost-cutting measures, and giving up old-fashioned procedures. Slater & Company became one of the leading manufacturing companies in the United States. Due to the oppressive rules and working conditions and a proposed cut of 25% in the wages of women workers by Slater and the other Mill Owners near Pawtucket, in 1824, this area was the site of the first factory strike in US history. Thus beginning the long struggle for human rights between factory workers and owners, which is continuing today.
Slater also hired recruiters to search for families willing to work at the mill. He advertised to attract more families to the mills.

Personal life
In 1791, Slater married
Hannah Wilkinson; she invented two-ply thread, becoming, in 1793, the first American woman to be granted a patent.
Samuel and Hannah had ten children together, although four died during infancy. Hannah died in 1812 from complications of childbirth, leaving Samuel with six young children to raise.
Along with his brother, Samuel started the
Slater family in America.
Slater married for a second time in 1817 to a widow, Esther Parkinson. As his business was extremely successful by this time, and as Parkinson also owned the property before their marriage, the couple had a
