Matthew Boulton

Matthew Boulton (; 3 September 1728 – 17 August 1809) was an English manufacturer and business partner of Scottish engineer James Watt. In the final quarter of the 18th century, the partnership installed hundreds of Boulton & Watt steam engines, which were a great advance on the state of the art, making possible the mechanisation of factories and mills. Boulton applied modern techniques to the minting of coins, striking millions of pieces for Britain and other countries, and supplying the Royal Mint with up-to-date equipment.
Born in Birmingham, he was the son of a Birmingham manufacturer of small metal products who died when Boulton was 31. By then Boulton had managed the business for several years, and thereafter expanded it considerably, consolidating operations at the Soho Manufactory, built by him near Birmingham. At Soho, he adopted the latest techniques, branching into silver plate, ormolu and other decorative arts. He became associated with James Watt when Watt's business partner, John Roebuck, was unable to pay a debt to Boulton, who accepted Roebuck's share of Watt's patent as settlement. He then successfully lobbied Parliament to extend Watt's patent for an additional 17 years, enabling the firm to market Watt's steam engine. The firm installed hundreds of Boulton & Watt steam engines in Britain and abroad, initially in mines and then in factories.
Boulton was a key member of the Lunar Society, a group of Birmingham-area men prominent in the arts, sciences, and theology. Members included Watt, Erasmus Darwin, Josiah Wedgwood and Joseph Priestley. The Society met each month near the full moon. Members of the Society have been given credit for developing concepts and techniques in science, agriculture, manufacturing, mining, and transport that laid the groundwork for the Industrial Revolution.
Boulton founded the Soho Mint, to which he soon adapted steam power. He sought to improve the poor state of Britain's coinage, and after several years of effort obtained a contract in 1797 to produce the first British copper coinage in a quarter century. His "cartwheel" pieces were well-designed and difficult to counterfeit, and included the first striking of the large copper British penny, which continued to be coined until decimalisation in 1971. He retired in 1800, though continuing to run his mint, and died in 1809. His image appears alongside James Watt on the Bank of England's new Series F £50 note.
== Background ==

Birmingham had long been a centre of the ironworking industry. In the early 18th century the town entered a period of expansion as iron working became easier and cheaper with the transition (beginning in 1709) from charcoal to coke as a means of smelting iron. Scarcity of wood in increasingly deforested England and discoveries of large quantities of coal in Birmingham's county of Warwickshire and the adjacent county of Staffordshire speeded the transition. Much of the iron was forged in small foundries near Birmingham, especially in the Black Country, including nearby towns such as Smethwick and West Bromwich. The resultant thin iron sheets were transported to factories in and around Birmingham. With the town far from the sea and great rivers and with canals not yet built, metalworkers concentrated on producing small, relatively valuable pieces, especially buttons and buckles. Frenchman Alexander wrote that while he had seen excellent cane heads, snuff boxes and other metal objects in Milan, "the same can be had cheaper and better in Birmingham". These small objects came to be known as "toys", and their manufacturers as "toymakers".
Boulton was a descendant of families from around Lichfield, his great-great-great-great grandfather, Rev. Zachary Babington, having been Chancellor of Lichfield. Boulton's father, also named Matthew and born in 1700, moved to Birmingham from Lichfield to serve an apprenticeship, and in 1723 he married Christiana Piers. The elder Boulton was a toymaker with a small workshop specialising in buckles. Matthew Boulton was born in 1728, their third child and the second of that name, the first Matthew having died at the age of two in 1726.
