Lewis Weston Dillwyn

Lewis Weston Dillwyn, FRS (21 August 1778 – 31 August 1855) was a British porcelain manufacturer, naturalist and Whig Member of Parliament (MP). Biography He was born in Walthamstow, Essex, the eldest son of William Dillwyn (1743–1824) and Sarah Dillwyn (née Weston). His father, a Pennsylvanian Quaker had returned to Britain in 1777 during Philadelphia's worst period in the American War of Independence and settled at Higham Lodge, Walthamstow, Essex, UK. William Dillwyn was a vociferous anti-slavery campaigner and toured England and South Wales in his work for the Anti-Slavery Committee. William Dillwyn was related to George Haynes through the Emlen and Physick families in Philadelphia and it is likely that the opportunity to buy the Cambrian Pottery in Swansea, Wales, from Haynes came about through these family connections in America. William's letters to his daughter Suzanna are held by the Library Company of Philadelphia and stored at the Historical Society of Pennsylvania. These letters show that the factory was bought by William to keep Lewis active while the latter was suffering from gout. The highlight of this period of production of Swansea Pottery was the opening by Lewis Weston Dillwyn and George Haynes of the Cambrian Company, the Swansea Potteries London Warehouse on Fleet Street which operated between 1806 and 1807. In 1814 the pottery took over the workforce of the Nantgarw Pottery and began to make porcelain. Lewis Weston Dillwyn however was also renowned for his published works on botany and conchology, including his 1809 work The British Confervae, an illustrated study of British freshwater algae. Dillwyn is credited with discovering several species of the Conferva genus. Among the botanical illustrators of The British Confervae are the artists William Jackson Hooker, Ellen Hutchins and William Weston Young. He was elected in 1804 as a Fellow of the Royal Society.
