James Hargreaves was first a carpenter and then a hand-loom weaver at Stanhill, Blackburn, probably making Blackburn Checks or Greys from linen warps and cotton weft. An invention ascribed to him doubled production in the preparatory carding process before spinning. Two or three cards were nailed to the same stock and the upper one was suspended from the ceiling by a cord and counterweight. Around 1762 Robert Peel (1750–1830) sought his assistance in constructing a carding engine with cylinders that may have originated with Daniel Bourn, but this was not successful. In 1764, inspired by seeing a spinning wheel that continued to revolve after it had been knocked over accidentally, Hargreaves invented his spinning jenny. The first jennies had horizontal wheels and could spin eight threads at once. To spin on this machine required a great deal of skill. A length of roving was passed through the clamp or clove. The left hand was used to close this and draw the roving away from the spindles which were rotated by the spinner turning the horizontal wheel with the right hand. The spindles twisted the fibres as they were being drawn out. At the end of the draw, the spindles continued to be rotated until sufficient twist had been put into the fibres to make the finished yarn. This was backed off from the tips of the spindles by reversing them and then, with the spindles turning in the spinning direction once more, the yarn was wound on by the right hand rotating the spindles, the left hand pushing the clove back towards them and one foot operating a pedal which guided the yarn onto the spindles by a faller wire. A piecer was needed to rejoin the yarns when they broke. At first Hargreaves's jenny was worked only by his family, but then he sold two or three of them, possibly to Peel. In 1768, local opposition and a riot in which his house was gutted forced him to flee to Nottingham. He entered into partnership there with Thomas James and established a cotton mill. In 1770 he followed Arkwright's example and sought to patent his machine and brought an action for infringement against some Lancashire manufacturers, who offered £3,000 in settlement. Hargreaves held out for £4,000, but he was unable to enforce his patent because he had sold jennies before leaving Lancashire. Arkwright's "water twist" was more suitable for the Nottingham hosiery industry trade than jenny yarn and in 1777 Hargreaves replaced his own machines with Arkwright's. When he died the following year, he is said to have left property valued at £7,000 and his widow received £400 for her share in the business. Once the jenny had been made public, it was quickly improved by other inventors and the number of spindles per machine increased. In 1784, there were reputed to be 20,000 jennies of 80 spindles each at work. The jenny greatly eased the shortage of cotton weft for weavers.

Kennedy was the third son of his father, Robert, and went to the village school in Dalry. On his father's death, he was sent at the age of 14 to Chowbent, Lancashire, where he was apprenticed to William Cannan, a maker of textile machines such as carding frames, Hargreaves's jennies and Arkwright's waterframes. On completion of his apprenticeship in 1791, he moved to Manchester and entered into partnership with Benjamin and William Sandford and James M'Connel, textile machine makers and mule spinners. In 1795 this partnership was terminated and one was made with James M'Connel to form the firm M'Connel \& Kennedy, cotton spinners.

Kennedy introduced improvements for spinning fine yarns and the firm of M'Connel \& Kennedy became famous for the quality of these products, which were in great demand. He made the spindles turn faster during the second part of the mule carriage's outward draw, and from 1793 onwards he experimented with driving mules by steam engines. Like William Kelly at New Lanark, he succeeded in making the spinning sequences power-operated by 1800, although the spinner had to take over the winding on. This made the mule into a factory machine, but it still required skilled operators. He was also involved with Henry Houldsworth, Junior, in the improvement of the roving frame. In 1803 Kennedy joined the Manchester Literary \& Philosophical Society, to which he presented several papers, including one in 1830 on "A memoir of Samuel Crompton". He retired from the spinning business in 1826, but continued his technical and mechanical pursuits. He was consulted about whether the Liverpool \& Manchester Railway should have moving or stationary steam engines and was an umpire at the Rainhill Trials in 1829.

The son of poor working parents, at the age of 6 an attack of smallpox left him blind; however, this did not restrict his future activities, which included swimming and riding. He learned the violin and was much employed as the fiddle-player at country parties. He saved enough money to buy a horse on which he hunted. He took part in bowls, wrestling and boxing, being a robust six foot two inches tall. He rode to Whitby and went thence by boat to London and made other trips to York, Reading and Windsor. In 1740 Colonel Liddell offered him a seat in his coach from London to Harrogate, but he declined and got there more quickly on foot. He set up a one-horse chaise and a four-wheeler for hire in Harrogate, but the local innkeepers set up in competition in the public hire business. He went into the fish business, buying at the coast and selling in Leeds and other towns, but made little profit so he took up his violin again. During the rebellion of 1745 he recruited for Colonel Thornton and served to fight at Hexham, Newcastle and Falkirk, returning home after the Battle of Culloden. He then started travelling between Yorkshire, where be bought cotton and worsted stockings, and Aberdeen, where he sold horses. He set up a twice-weekly service of stage wagons between Knaresborough and York.

In 1765 an Act was passed for a turnpike road between Harrogate and Boroughbridge and he offered to build the Master Surveyor, a Mr Ostler, three miles (5 km) of road between Minskip and Fearnly, selling his wagons and his interest in the carrying business. The road was built satisfactorily and on time. He then quoted for a bridge at Boroughbridge and for a turnpike road between Knaresborough and Harrogate. He built many other roads, always doing the survey of the route on his own. The roads crossed bogs on a base of ling and furze. Many of his roads outside Yorkshire were in Lancashire, Cheshire and Derbyshire. In all he built some 180 miles (290 km) of road, for which he was paid some £65,000.

He worked for thirty years on road building, retiring in old age to a cotton business in Stockport where he had six spinning jennies and a carding engine; however, he found there was little profit in this so he gave the machinery to his son-in-law. The last road he built was from Haslington to Accrington, but due to the rise in labour costs brought about by the demand from the canal boom, he only made £40 profit on a £3,000 contract; the road was completed in 1792, when he retired to his farm at Spofforth at the age of 75. There he died, leaving a wife, four children, twenty grandchildren and ninety greatgrandchildren. His wife was the daughter of the landlord of the Granby Inn, Knaresborough.
