Relatively little is known about William Shakespeare's life although the words attributed to him have profoundly impacted not just English literature but the English language. Whether Shakespeare's plays were written by an individual or collaboratively within the theater company The King's Men continues to be debated, but Shakespeare's name was the one attached to his plays and poetry from the earliest publications, the initial quarto editions and later the First, Second, Third, and Fourth Folios.
