Today, April 23, 2016, marks the 400th death anniversary of one of English literature’s greatest writers, a man who had a huge hand in making English what it is today. Though William Shakespeare’s date of birth is unknown, he died on this day, nearly 52 years after he was baptized. In less than half a century, he created a corpus of work that has endured—and continues to spawn adaptations by the dozen in popular culture—ever since.
