Long Days Journey into Night was written in 1940 but not staged until 1956, after ONeills death. Unashamedly autobiographical, it is, as he puts it himself in the dedicatory note, a play of old sorrow, written in tears and blood, a harrowing attempt to understand himself and his family.Publisher: Vintage PublishingAuthor(s): Eugene ONeillNumber of pages: 160Publication date: 1956Dimensions: 198 x 129 x 12Cover type: Paperback / softback
