Richard Dewsberry was the Dewsberry in Guest and Dewsberry who re-opened the Llanelly Pottery in 1877. He had come to Llanelli to help his uncle David Guest revive the business which had been closed for two years due to the financial problems of its previous owners Coombs and Holland. He became a leading member of the Liberal Club, Park Church and the Llanelli Mechanics Institute (later the Public Library) and was described in his obituary as “one of our most respected townsmen” who "took a deep interest in educational matters". He suffered for many years from heart trouble before he collapsed and died at work in 1906.
