Was born in Swansea into a family whose roots were in Gower, and educated at Magdalen College, Oxford, where he read Romance languages. After serving in the Second World War as an interpreter with the British Naval Mission to the French Provisional Government, he worked with Keidrych Rhys at the Druid Press in Carmarthen, and eventually as a librarian, first at Dowlais in Merthyr Tydfil and later at Mountain Ash in Glamorgan. He entered politics in the ranks of the Welsh Republican Movement, but from 1959 was active on behalf of Plaid Cymru (the Welsh nationalist party), editing the party's newspaper. In 1965, while living in Merthyr Tydfil, he was associated with Meic Stephens in the launching of the magazine Poetry Wales, and they collaborated in the writing of political ballads.
