Philip Madoc (5 July 1934 – 5 March 2012) was a Welsh actor who had many television and film roles, including the lead roles in the detective series A Mind to Kill and The Life and Times of David Lloyd George. He is, however, perhaps most widely remembered for his role as a U-boat captain in an episode of Dad's Army.

Madoc was born Phillip Jones near Merthyr Tydfil and attended Cyfarthfa Castle Grammar School where he was a member of the cricket and rugby teams and displayed talent as a linguist. He then studied languages at the University of Wales and the University of Vienna, speaking seven languages, including Russian and Swedish and had a working knowledge of Huron Indian, Hindi and Mandarin. He worked as an interpreter, becoming very disenchanted with having to translate for politicians: “I did dry-as-dust jobs like political interpreting. You get to despise politicians when you have to translate the rubbish they spout”, before switching to drama and winning a place at RADA.

Dylan Marlais Thomas (27 October 1914 – 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 in "And death shall have no dominion" and "Fern Hill".

Dylan Thomas was born in the Uplands area of Swansea, Glamorgan, Wales, on 27 October 1914 just a few months after the Thomas family had bought the house. Uplands was, and still is, one of the more affluent areas of the city.

His father, David John Thomas (1876–1952), had attained a first-class honours degree in English at University College, Aberystwyth, and was dissatisfied with his position at the local grammar school as an English master who taught English literature. His mother, Florence Hannah Thomas (née Williams) (1882–1958), was a seamstress born in Swansea. Nancy, Thomas's sister, (Nancy Marles 1906–1953) was nine years older than he. Their father brought up both children to speak only English, even though he and his wife were both bilingual in English and Welsh. David was even known to give Welsh lessons at home.
