Which of these playwrights wrote "Beyond the Horizon"?

"Beyond the Horizon" is a play written by American playwright Eugene O'Neill. Although he first copyrighted the text in June 1918, O'Neill continued to revise the play throughout the rehearsals for its 1920 premiere.

His first full-length work to be staged, "Beyond the Horizon" won the 1920 "Pulitzer Prize for Drama".

"Beyond the Horizon" premiered on Broadway at the Morosco Theatre, from February 3, 1920 to February 20, 1920, transferred to the Criterion Theatre from February 24, 1920 to March 5, 1920, and finally transferred to the Little Theatre, from March 9, 1920 to June 26, 1920.

Beyond the Horizon tells the story of the two Mayo brothers, Andrew “Andy” and Robert “Rob,” who realize that they are both in love with the same woman, Ruth Atkins. The play is set on the Mayo family farm and takes place over the course of eight years.

Eugene Gladstone O'Neill (October 16, 1888 – November 27, 1953) was an American playwright. His poetically titled plays were among the first to introduce into the U.S. the drama techniques of realism, earlier associated with Chekhov, Ibsen, and 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". He was awarded the 1936 "Nobel Prize in Literature". O'Neill is also the only playwright to win four "Pulitzer Prizes for Drama".
