John Wyatt was the eldest son of John and Jane Wyatt, who lived in the small village of Thickbroom in the parish of Weeford, near Lichfield. John the younger was educated at Lichfield school and then worked as a carpenter at Thickbroom till 1730. In 1732 he was in Birmingham, engaged by a man named Heely, a gunbarrel forger, who became bankrupt in 1734. Wyatt had invented a machine for making files and sought the help of Lewis Paul to manufacture this commercially.

The surviving papers of Paul and Wyatt in Birmingham are mostly undated and show a variety of machines with which they were involved. There was a machine for "making lead hard" which had rollers, and "a Gymcrak of some consequence" probably refers to a machine for boring barrels or the file-making machine. Wyatt is said to have been one of the unsuccessful competitors for the erection of London Bridge in 1736. He invented and perfected the compound-lever weighing machine. He had more success with this: after 1744, machines for weighing up to five tons were set up at Birmingham, Chester, Gloucester, Hereford, Lichfield and Liverpool. Road construction, bridge building, hydrostatics, canals, water-powered engines and many other schemes received his attention and it is said that he was employed for a time after 1744 by Matthew Boulton.

It is certain that in April 1735 Paul and Wyatt were working on their spinning machine and Wyatt was making a model of it in London in 1736, giving up his work in Birmingham. The first patent, in 1738, was taken out in the name of Lewis Paul. It is impossible to know which of these two invented what. This first patent covers a wide variety of descriptions of the vital roller drafting to draw out the fibres, and it is unknown which system was actually used. Paul's carding patent of 1748 and his second spinning patent of 1758 show that he moved away from the system and principles upon which Arkwright built his success. Wyatt and Paul's spinning machines were sufficiently promising for a mill to be set up in 1741 at the Upper Priory, Birmingham, that was powered by two asses. Wyatt was the person responsible for constructing the machinery. Edward Cave established another at Northampton powered by water while later Daniel Bourn built yet another at Leominster. Many others were interested too. The Birmingham mill did not work for long and seems to have been given up in 1743. Wyatt was imprisoned for debt in The Fleet in 1742, and when released in 1743 he tried for a time to run the Birmingham mill and possibly the Northampton one. The one at Leominster burned down in 1754, while the Northampton mill was advertised for sale in 1756. This last mill may have been used again in conjunction with the 1758 patent. It was Wyatt whom Daniel Bourn contacted about a grant for spindles for his Leominster mill in 1748, but this seems to have been Wyatt's last association with the spinning venture.

When Arthur Woolf left the Griffin Brewery, London, in October 1808, he formed a partnership with Humphrey Edwards, described as a millwright at Mill Street, Lambeth, where they started an engine works to build Woolf's type of compound engine. A number of small engines were constructed and other ordinary engines modified with the addition of a high-pressure cylinder. Improvements were made in each succeeding engine, and by 1811 a standard form had been evolved. During this experimental period, engines were made with cylinders side by side as well as the more usual layout with one behind the other. The valve gear and other details were also improved. Steam pressure may have been around 40 psi (2.8 kg/cm²). In an advertisement of February 1811, the partners claimed that their engines had been brought to such a state of perfection that they consumed only half the quantity of coal required for engines on the plan of Messrs Boulton \& Watt. Woolf visited Cornwall, where he realized that more potential for his engines lay there than in London; in May 1811 the partnership was dissolved, with Woolf returning to his home county. Edwards struggled on alone in London for a while, but when he saw a more promising future for the engine in France he moved to Paris. On 25 May 1815 he obtained a French patent, a Brevet d'importation, for ten years. A report in 1817 shows that during the previous two years he had imported into France fifteen engines of different sizes which were at work in eight places in various parts of the country. He licensed a mining company in the north of France to make twenty-five engines for winding coal. In France there was always much more interest in rotative engines than pumping ones. Edwards may have formed a partnership with Goupil \& Cie, Dampierre, to build engines, but this is uncertain. He became a member of the firm Scipion, Perrier, Edwards \& Chappert, which took over the Chaillot Foundry of the Perrier Frères in Paris, and it seems that Edwards continued to build steam engines there for the rest of his life. In 1824 it was claimed that he had made about 100 engines in England and another 200 in France, but this is probably an exaggeration.

The Woolf engine acquired its popularity in France because its compound design was more economical than the single-cylinder type. To enable it to be operated safely, Edwards first modified Woolf s cast-iron boiler in 1815 by placing two small drums over the fire, and then in 1825 replaced the cast iron with wrought iron. The modified boiler was eventually brought back to England in the 1850s as the "French" or "elephant" boiler.
