Question: What is the date of death of the founder of Boulton And Watt?

Knowledge 1: Boulton and Watt
Boulton & Watt was an early British engineering and manufacturing firm in the business of designing and making marine and stationary steam engines.Founded in the English West Midlands around Birmingham in 1775 as a partnership between the English manufacturer Matthew Boulton and the Scottish engineer James Watt, the firm had a major role in the Industrial Revolution and grew to be a major producer of steam engines in the 19th century. [SEP] Knowledge 2: 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 his partner James Watt on the Bank of England's current Series F £50 note.

James Watt( 30 January 1736 – 25 August 1819) was a Scottish inventor, mechanical engineer, and chemist who improved on Thomas Newcomen's 1712 Newcomen steam engine with his Watt steam engine in 1776, which was fundamental to the changes brought by the Industrial Revolution in both his native Great Britain and the rest of the world.While working as an instrument maker at the University of Glasgow, Watt became interested in the technology of steam engines.He realised that contemporary engine designs wasted a great deal of energy by repeatedly cooling and reheating the cylinder.Watt introduced a design enhancement, the separate condenser, which avoided this waste of energy and radically improved the power, efficiency, and cost-effectiveness of steam engines.Eventually he adapted his engine to produce rotary motion, greatly broadening its use beyond pumping water.Watt attempted to commercialise his invention, but experienced great financial difficulties until he entered a partnership with Matthew Boulton in 1775.The new firm of Boulton and Watt was eventually highly successful and Watt became a wealthy man.In his retirement, Watt continued to develop new inventions though none was as significant as his steam engine work.He developed the concept of horsepower, and the SI unit of power, the watt, was named after him.
