Dylan Thomas was a Welsh poet born in 1914 who is known for his poem "Do Not Go Gentle Into That Good Night." He showed an early talent for poetry, writing drafts of his works as a teenager. Thomas struggled financially throughout his life and supported himself through jobs like the BBC while living with his wife Caitlin. His poems were meticulously constructed over many drafts using sound, imagery, and association. "Do Not Go Gentle Into That Good Night" uses a villanelle form and light/dark imagery to reinforce the theme of not accepting death passively.
