Matthew Boulton, English entrepreneur, industrialist and engineer, 1809. English works owner Boulton (1728-1809) (front) and Scottish engineer and inventor James Watt (1736-1819) formed a partnership in 1773 to produce steam engines. Boulton's factory at Soho, near Birmingham, produced the first of the revolutionary steam engines designed by Watt. By the early 19th century over 500 Boulton and Watt engines were being used in Britain's mines and factories. From a medal struck to mark Boulton's death.
