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

, he was called "Slater the Traitor"
and "Sam the Slate" because he brought British textile technology to the United States, modifying it for American use. He memorized the textile factory machinery designs as an apprentice to a pioneer in the British industry before migrating to the U.S. at the age of 21.
Slater designed the first textile mill in the U.S. He later went into business for himself, developing a family business with his sons. He eventually owned 13 spinning mills and developed tenant farms and company towns around them. One of these towns was

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 memorized as much as he could, and departed for

.
In August 1789, they acquired a 32-spindle frame "after the
Arkwright 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. Slater found no mechanics in the U.S. when he arrived and had great difficulty finding someone to build the machinery. Eventually he located Oziel Wilkinson and his son David to produce iron castings and forgings for the machinery. According to
David Wilkinson: "all the turning of the iron for the cotton machinery built by Mr. Slater was done with hand chisels or tools in lathes turned by cranks with hand power".
By 1791 Slater had some of the equipment operating, despite shortages of tools and skilled mechanics. He was able to single-handedly construct from memory the water-powered spinning machinery.
By December, the shop was operational with ten to twelve workers. In 1793, Slater and Brown
opened their first factory in Pawtucket.
Slater knew the secret of Arkwright's success, including varying fiber lengths and 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 the U.S.
After developing this mill, Slater instituted management principles that he had learned from Strutt and Arkwright to teach workers to be skilled mechanics. This included child labor similar to what existed in England.
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.
Rhode Island System

Slater created the Rhode Island System, which were factory practices based upon the close knit family life patterns in

Children aged seven to 12 were the first employees of the mill; Slater personally supervised them. The first child workers were hired in 1790., it is implausible that Slater resorted to physical punishment of children, relying instead on a system of fines. Slater also brought a

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 hired recruiters to search for families willing to work at the mill. He advertised to attract more families to the mills.
By 1800, the Slater mill's success had been duplicated by other entrepreneurs. By 1810,

. That war resulted in speeding up the process of industrialization in New England. By war's end in 1815, there were 140 cotton manufacturers within 30 miles of
Providence, employing 26,000 hands and operating 130,000 spindles. The American textile industry was launched.
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 in 1824 by Slater and the other Mill Owners near Pawtucket, the women resisted and conducted the first factory strike in US history. This began the long struggle for human rights between factory workers and owners, which continues today.
Slater resisted unionization. In response to rapidly changing textile technology, he modernized his factories and later shifted operations to the

Personal life
In 1791, Slater married
Hannah Wilkinson. She invented two-ply thread in 1793, and became the first American woman to be granted a patent. Samuel and Hannah had ten children together; four died during infancy. Hannah died in 1812 from complications of childbirth, leaving Samuel with six young children to raise.
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 arranged for a
pre-nuptial agreement.
Along with his brother, Samuel started the
Slater family in America.
