Geoffrey Chaucer was an English poet and author. Widely considered the greatest English poet of the Middle Ages. He has been called the "father of English literature", or, alternatively, the "father of English poetry". He was the first writer to be buried in what has since come to be called Poets' Corner, in Westminster Abbey.
