Dylan Marlais Thomas (27 October 1914 – 9 November 1953) was a Welsh poet and writer whose works include the poems "Do not go gentle into that good night" and "And death shall have no dominion", as well as the "play for voices" Under Milk Wood. He also wrote stories and radio broadcasts such as A Child's Christmas in Wales and Portrait of the Artist as a Young Dog. He became widely popular in his lifetime; and remained so after his death at the age of 39 in New York City. By then, he had acquired a reputation, which he had encouraged, as a "roistering, drunken and doomed poet". Dylan Marlais Thomas was the son of David John Thomas, a school master, and Florence Hannah Williams who married in 1903 and were living in Sketty Avenue, Sketty, Swansea when the 1911 Census was taken. Their daughter Nancy, born 1906, was not at home with them on Census Day.

Dylan Thomas was born in Uplands, Swansea, in 1914, leaving school in 1932 to become a reporter for the South Wales Daily Post. Many of his works appeared in print while he was still a teenager. In 1934, the publication of "Light breaks where no sun shines" caught the attention of the literary world. While living in London, Thomas met Caitlin Macnamara; they married in 1937 and had three children: Llewelyn, Aeronwy, and Colm.
