Samuel Slater

• 1. Introduction

  ›

  Samuel Slater made a promise that could have ended his career before it began. Standing before Rhode Island merchant Moses Brown, the young Englishman said that if he could not make yarn as good as what they made in England, he would throw everything he had attempted over the bridge. It was a remarkable pledge from a man who had arrived in America with no machinery, no blueprints, and no skilled craftsmen to help him. What he did have was his memory. Slater had spent years absorbing every detail of Britain's most closely guarded industrial secret: the water-powered textile mill. British law made it illegal to export those designs. Slater exported them anyway, carrying them inside his head across the Atlantic. He was called "Slater the Traitor" back home. In America, Andrew Jackson would one day call him the "Father of the American Industrial Revolution". How a farmer's son from Derbyshire became the man who transplanted a nation's industrial engine into new soil is a story of ambition, memory, broken loyalty, family empire, and a factory system that reshaped both work and workers in ways Slater himself may not have foreseen.

• 2. A Derbyshire Apprenticeship

  ›

  Slater was born on the 9th of June, 1768, in Belper, Derbyshire, to William and Elizabeth Slater. He was the fifth of eight children in a farming family, and his early schooling was likely provided at a local school run by a man named Thomas Jackson. At age ten, he entered the cotton mill that Jedediah Strutt had opened that same year. The mill used the water frame pioneered by Richard Arkwright at the nearby Cromford Mill, and it was here that Slater's real education began. When his father died in 1782, the family formalized the arrangement by indentoring Samuel to Strutt as an apprentice. Strutt proved an exacting teacher. By the time Slater turned 21, he possessed a thorough command of every stage of cotton spinning, from the organization of a factory floor down to the behavior of individual machines. He learned of American interest in replicating British textile technology. He also knew that British law forbade exporting the designs. Rather than risk being caught with documents, he committed as much as he could to memory, then departed for New York City in 1789. The people of Belper, who depended on Strutt's mills for their livelihoods, had a name for him: "Slater the Traitor".

• 3. Building From Memory

  ›

  Moses Brown had a problem. In August 1789, his firm Almy and Brown had acquired a 32-spindle frame built after the Arkwright pattern, and no one could operate it. When Slater's letter arrived offering his services, Brown was skeptical but willing. Slater assessed the machinery and told Brown plainly that nothing could be done with it as it stood. The contract signed in 1790 gave Slater the funds to build proper water frames and associated machinery, along with a half share in their capital value and the profits from them. Finding someone to actually build the parts proved nearly as hard as getting across the Atlantic. Slater could not locate any mechanics in America with the skills he needed. He eventually tracked down Oziel Wilkinson and his son David, who were able to produce iron castings and forgings. David Wilkinson later recalled that all the turning of the iron for the cotton machinery was done with hand chisels or tools in lathes turned by cranks with hand power. Working through shortages of tools and skilled labor, Slater had some equipment operating by 1791, the entire water-powered spinning apparatus reconstructed from memory. By December of that year, the shop was running with ten to twelve workers. Two years later, in 1793, Slater and Brown opened their first formal factory in Pawtucket. Slater understood not only the individual machines but Arkwright's full carding, drawing, and roving sequence as a continuous production system, and he made targeted adjustments to the designs to suit local conditions. The result was the first successful water-powered roller spinning textile mill in the United States.

• 4. The Rhode Island System

  ›

  Slater did not simply copy England's factory model. He adapted it to the social grain of New England village life, creating what became known as the Rhode Island System. Back in England, Strutt and Arkwright had employed women and children. Slater took a different approach in America: he recruited whole families. He built company-owned housing near the mills and established company stores. He also sponsored a Sunday school where college students taught the mill children reading and writing. The first child workers at the mill were children aged seven to twelve, hired in 1790, and Slater personally supervised them. He had brought the Sunday school model from England and transplanted it alongside the machinery. In 1793, Slater built a new mill specifically for textile manufacture under the firm Almy, Brown and Slater. That mill ran 72 spindles. The same year, Eli Whitney's cotton gin received its patent, an invention that would powerfully reshape the world Slater's mills depended upon. By reducing the labor required to process short-staple cotton, Whitney's device made profitable the cultivation of that variety across the interior uplands of the South, far from the Sea Island cotton country on the coast. The Deep South expanded cotton cultivation dramatically, especially after the Indian Removal of the 1830s forced most of the Five Civilized Tribes west of the Mississippi. New England's free mill workers, and the system Slater had built, ran on cotton produced by enslaved African Americans in the South.

• 5. Empire and Its Limits

  In 1798, Slater split from Almy and Brown and formed Samuel Slater and Company, this time in partnership with his father-in-law, Oziel Wilkinson. He expanded into Connecticut, Massachusetts, New Hampshire, and Rhode Island. His brother John arrived from England in 1799. John was a wheelwright who had studied the latest British developments, possibly including the spinning mule, and Samuel placed him in charge of a large operation called the White Mill. By 1810, Slater held partial ownership in three factories across Massachusetts and Rhode Island. He also built factories dedicated to producing the textile machinery that supplied many of the region's mills, and he formed a separate iron partnership with a brother-in-law. By that same year, U.S. Secretary of the Treasury Albert Gallatin counted roughly 50 cotton-yarn mills in operation across the country, many of them launched in response to the Embargo of 1807, which cut off imports from Britain ahead of the War of 1812. That war sped up industrialization in New England. By the time it ended in 1815, there were 140 cotton manufacturers within 30 miles of Providence, employing 26,000 hands and running 130,000 spindles. Slater's original mill had seeded a revolution. But success at that scale came with costs. Slater found himself spread too thin, unable to coordinate his many different business interests. He refused to hire managers from outside the family. After 1829, he brought his sons into a new umbrella firm called Samuel Slater and Sons. It was his son Horatio Nelson Slater who ultimately reorganized the family business, introduced cost-cutting measures, and cleared away the old-fashioned procedures that had accumulated.

• 6. Workers and the First Strike

  ›

  The workers inside Slater's mills were not passive. The Rhode Island System had shaped a workforce built around families, but those families also had grievances. In 1824, Slater and the other mill owners near Pawtucket proposed cutting women workers' wages by 25%. The women resisted. What followed was the first factory strike in United States history. Slater's response to that action and to wider labor organizing was consistent: he resisted unionization throughout his career. As textile technology changed rapidly in the years that followed, he modernized his factories and eventually shifted some operations to the South. The management principles he had learned from Strutt and Arkwright, which he had introduced to American workers, included child labor on the English pattern. Children aged seven to twelve were the first to staff his mill floors. Slater's position was not unique in his era, but the strike of 1824 made plain that the Rhode Island System's community ties did not prevent workers from organizing against the people who ran those communities.

• 7. Personal Life and the Wilkinsons

  ›

  In 1791, the same year his Pawtucket machinery first ran, Slater married Hannah Wilkinson, daughter of Oziel Wilkinson, who had helped him forge the iron parts for his first machines. Hannah was an inventor in her own right. In 1793, she invented two-ply thread and became the first American woman to receive a patent. Samuel and Hannah had ten children together; four died in infancy. Hannah died in 1812 from complications of childbirth, leaving Samuel to raise six young children alone. Slater married again in 1817, this time to a widow named Esther Parkinson. By then his business was sufficiently successful, and Parkinson owned property of her own before the marriage; the couple arranged a pre-nuptial agreement. It was one of the more practical arrangements in a life defined by practical decisions.

• 8. Death and What He Left Behind

  ›

  Slater died on the 21st of April, 1835, in Webster, Massachusetts, a town he had founded in 1832 and named after his friend Senator Daniel Webster. He is buried in Mount Zion Cemetery. At his death he owned 13 mills and a fortune of 1.3 million dollars, a sum whose income value was calculated at 1.12 billion dollars in 2022. His original mill in Pawtucket still stands, listed on the National Register of Historic Places and operated today as Slater Mill, a museum dedicated to his history and his contribution to American industry. That mill and the town of Slatersville, Rhode Island, are both part of the Blackstone River Valley National Historical Park. His papers are held at the Baker Library of Harvard Business School in Boston. In March 2022, a history museum called the Samuel Slater Experience opened in Webster, the town he built and named for a senator he admired.
