A Portrait of the Artist as a Young Dog (1940) is a group of autobiographical sketches and Adventures in the Skin Trade (published posthumously, 1954) contains an unfinished novel and other prose pieces. During World War II (1939-1945) Thomas wrote scripts for documentary motion pictures. After the war Thomas was a literary commentator for BBC radio. Under Milk Wood (published posthumously, 1954), a play for voices, was originally written for radiobroadcast; when Thomas read it for its first public performance in Cambridge, Massachusetts, in 1953, it was still unfinished. The work became his most famous piece; it evokes the lives of the inhabitants of Llareggub, a small, Welsh seaside town. Noted for his readings of his own verse, Thomas became legendary in the United States, where he gave many lecture tours and gained a wide following. Nevertheless, his last years were shadowed by an increasingly tragic view of his own tempestuous life. His death in New York City on November 9, 1953, was brought on by alcoholism.
