Plymouth
Local chemist William Cookworthy established his somewhat short-lived Plymouth Porcelain venture in 1768 to exploit the recently discovered deposits of local China Clay - an industry which continues to make up a portion of the city income. As an associate and host of engineer John Smeaton he was indirectly involved with the development of the Eddystone Lighthouse.
