Dylan Marlais Thomas (27 October 1914Â â 9 November 1953) was a Welsh poet and writer who wrote exclusively in English. In addition to poetry, he wrote short stories and scripts for film and radio, which he often performed himself. His public readings, particularly in America, won him great acclaim; his sonorous voice with a subtle Welsh lilt became almost as famous as his works. His best-known works include the "play for voices" Under Milk Wood and the celebrated villanelle for his dying father, "Do not go gentle into that good night". Appreciative critics have also noted the craftsmanship and compression of poems such as "In my Craft or Sullen Art" and the rhapsodic lyricism of "Fern Hill''".
