Soho Foundry is a factory created in 1775 by Matthew Boulton and James Watt and their sons Matthew Robinson Boulton and James Watt Jr. at Smethwick, West Midlands, England, for the manufacture of steam engines. Now owned by Avery Weigh-Tronix, it is used for the manufacture of weighing machines.

The Industrial Revolution, sometimes divided into the First Industrial Revolution and Second Industrial Revolution, was a period of global transition of the human economy towards more widespread, efficient and stable manufacturing processes that succeeded the Agricultural Revolution. Beginning in Great Britain, the Industrial Revolution spread to continental Europe and the United States, during the period from around 1760 to about 1820–1840. This transition included going from hand production methods to machines; new chemical manufacturing and iron production processes; the increasing use of water power and steam power; the development of machine tools; and the rise of the mechanized factory system. Output greatly increased, and the result was an unprecedented rise in population and the rate of population growth. The textile industry was the first to use modern production methods, and textiles became the dominant industry in terms of employment, value of output, and capital invested.
