Lexicographer, grammarian, editor, antiquarian and poet. The son of John Owen, he adopted the surname Pughe in 1806 after inheriting property from a relative. A leading member of the Society of Gwyneddigion and the Society of the Cymmrodorion, his publications included: The Heroic Elegies of Llywarch Hen (1792), The Myvyrian Archaiology (1801, 1807) and The Cambrian Biography (1803). In 1796–1797, Southey and Pughe engaged in a (pseudonymous) debate about the Welsh language in the pages of the Monthly Magazine. Later in 1797, Southey consulted Pughe about details for his Welsh-American poem Madoc. Pughe susbsequently became one of the principal disciples of the self-proclaimed prophet Joanna Southcott.
