Thomas was born at home in the Uplands district of Swansea, Wales, on October 27, 1914, the second child and only son of middle-class parents. His sister Nancy was nearly nine years older than he. His father was a schoolmaster in English at the local grammar school. Though considered a cold and bitter man who resented his position as a teacher, the elder Thomas's love for literature encouraged a similar devotion in his son. Thomas feared, respected, and deeply loved his father, and in some sense his life appeared to be an attempt to realize his father's frustrated dream of being a great poet. In contrast to his father, Thomas's mother was loving, overly protective, and inclined to overindulge her son. Even at the end of his life, she found no fault in his public behavior and the drinking habits which ultimately led to his death.
