auxiliary information: William Shakespeare was an English poet, playwright, and actor, widely regarded as the greatest writer in the English language and the world's pre-eminent dramatist. He is often called England's national poet, and the "Bard of Avon". His extant works, including collaborations, consist of approximately 38 plays, 154 sonnets, two long narrative poems, and a few other verses, for which the authorship of some is uncertain. His plays have been translated into every major living language and are performed more often than those of any other playwright. Shakespeare was born and brought up in Stratford-upon-Avon, Warwickshire. At the age of 18, he married Anne Hathaway, with whom he had three children: Susanna, and the twins Hamnet and Judith. Between 1585 and 1592, he began what became a successful career in London as an actor, writer, and part-owner of a playing company called the Lord Chamberlain's Men, later known as the King's Men. He appears to have retired to Stratford around 1613, at age 49, where he died three years later.
