The play was written by Oscar Wilde. He was born on Oct. 16, 1854.
Within the play, "Bunbury" was also used a verb. To go "bunburying" meant to fake your way out of an unpleasant situation.
That was just one of the play's many examples of false identities, which is something Wilde knew about from personal experience. He was gay at a time when society treated his sexuality as a crime. When his secret became public, he was tried for gross indecency and sentenced to two years of hard labor.
