Josiah Wedgwood (12 July 1730 – 3 January 1795) was an English potter and entrepreneur who founded the Wedgwood company. Wedgwood belonged to the fourth generation of a family of potters whose traditional occupation continued through another five generations. He is credited with the industrialisation of the manufacture of pottery. A prominent abolitionist, Wedgwood is remembered too for his "Am I Not a Man And a Brother?" anti-slavery medallion. He was a member of the Darwin–Wedgwood family, and he was the grandfather of Charles and Emma Darwin.
One of the wealthiest entrepreneurs of the 18th century, Wedgwood created goods to meet the demands of the consumer revolution and growth in wealth of the middle classes that helped drive the Industrial Revolution in Britain. He is credited as the inventor of modern marketing, specifically direct mail, money back guarantees, travelling salesmen, carrying pattern boxes for display, self-service, free delivery, buy one get one free, and illustrated catalogues. Wedgwood is also noted as an early adopter/founder of managerial accounting principles in Anthony Hopwood's "Archaeology of Accounting Systems."
He was elected to the Royal Society in 1783 for the development of a pyrometer, a device to measure the extremely high temperatures that are found in kilns during the firing of pottery.
He was an active member of the Lunar Society of Birmingham often held at Erasmus Darwin House and is remembered on the Moonstones in Birmingham.Josiah Wedgwood in Wikipedia
