Eugene Gladstone O'Neill was an American playwright awarded the 1936 Nobel Prize in Literature. His poetically titled plays were among the first to introduce into the U.S. the drama techniques of realism, earlier associated with Russian playwright Anton Chekhov, Norwegian playwright Henrik Ibsen, and Swedish playwright August Strindberg. The tragedy Long Day's Journey into Night is often included on lists of the finest U.S. plays in the 20th century, alongside Tennessee Williams's A Streetcar Named Desire and Arthur Miller's Death of a Salesman.
