George Haynes (1745–1830) was a British entrepreneur, pottery manufacturer, banker, and newspaper proprietor of Swansea, Wales.
Haynes was born in 1745 to a Quaker family with its origins in Henley-in-Arden, Warwickshire, although his exact place of birth and continuing religious affiliations are uncertain.
Under his management the concern flourished and produced high quality porcelain; Haynes was probably the only person in south Wales at this time to have any knowledge of the processes involved in its manufacture.
However, in 1802 William Dillwyn purchased the remainder of the lease and invested a substantial amount of capital in the business.
He also took an active part in municipal affairs and was concerned with improvements to paving and lighting the town and to its postal services.
Following legal action on the part of Dillwyn on the grounds of the nuisance caused by its activities, it was forced to close almost immediately.
[9] Over the following two years several sales of the property of Haynes and of his son William took place, including the brewery in Swansea and household furniture from his house at Clydach.
[10] His contribution to the development of Swansea, and to all aspects of its social and economic life, at a time when the town was generally regarded as being the centre of polite society in south Wales and as one of the most important centres of industrial activity in the country, was considerable, although it has not been sufficiently recognised.
