D. Gwenallt Jones

David James Jones (18 May 1899 – 24 December 1968), commonly known by his bardic name Gwenallt, was a Welsh poet, critic, and scholar, and one of the most important figures of 20th-century Welsh-language literature. He created his bardic name by transposing Alltwen, the name of the village across the river from his birthplace. Provided by Wikipedia
