Who invented the spinning jenny?
Spinning jenny, early multiple-spindle machine for spinning wool or cotton, invented by James Hargreaves in England and patented in 1770. By enabling a single worker to spin multiple threads simultaneously, the hand-powered spinning jenny dramatically increased the productivity of yarn-making and helped transform textile manufacturing during the Industrial Revolution.
Background
Spinning is the process of drawing out and twisting fibers, such as cotton, wool, or flax, to produce a continuous thread or yarn. Spinning is especially important for naturally short fibers, such as cotton, which must be twisted together to form yarn of sufficient length and strength for weaving. From early times through the Middle Ages, spinning was performed by hand using a distaff and a spindle. The spinning wheel, likely invented in India and introduced to Europe in the Middle Ages, mechanized the process but generally produced only one thread at a time. As improvements in weaving technology—particularly the invention of the flying shuttle in 1733—increased the speed of cloth production, demand grew for a faster means of producing yarn.
Hargreaves’s breakthrough
About 1764 James Hargreaves, a poor, uneducated spinner and weaver living in Lancashire, England, conceived a new kind of spinning machine that would draw thread from several spindles simultaneously instead of just one. The idea reportedly occurred to him after his daughter accidentally knocked over the family’s spinning wheel. The spindle continued to turn even as the machine lay on the floor, suggesting to Hargreaves that a single wheel could turn several spindles at once.

Intended for domestic use or for small workshops, Hargreaves’s original spinning jenny had eight spindles arranged in a row and operated by a single hand-turned wheel. The operator used a sliding carriage to draw out the fibers, which were twisted into yarn by the rotating spindles. The newly spun yarn was then wound onto the spindles as the carriage was returned to its starting position. Later versions incorporated dozens of spindles, allowing a single worker to produce far more yarn than was possible with a traditional spinning wheel. The spinning jenny’s main limitation was that it produced weaker thread suitable only for use as weft (filling yarn).
Although the spinning jenny greatly increased the productivity of yarn-making, its introduction also provoked resistance from workers who feared that the new machinery would threaten their livelihoods. In 1768 a number of Hargreaves’s machines were reportedly destroyed by workers opposed to the invention, and he subsequently moved to Nottingham, where he established a small spinning mill.
Later developments
Hargreaves’s invention helped pave the way for further advances in spinning technology. In 1769 Sir Richard Arkwright patented the water frame, a spinning machine that was powered by water and was capable of making stronger yarn than the spinning jenny. While the hand-powered spinning jenny could be operated in homes or small workshops, the water frame’s reliance on waterpower encouraged the development of large textile factories. In 1779 Samuel Crompton invented the spinning mule, which was capable of spinning fine as well as coarse yarn and eventually made it possible for a single operator to work more than 1,000 spindles simultaneously. Highly productive and efficient, the spinning mule helped establish yarn spinning as a large-scale industrial process.
