This is a volume of specially commissioned essays containing studies of Eugene O'Neill's life, his intellectual and creative forebears, and his relation to the theatrical world of his creative period, 1916–42. Also included are descriptions of the O'Neill canon and its production history on stage and screen, and a series of essays on 'special topics' related to the playwright, such as his treatment of women in the plays, his portrayals of Irish and African Americans, and his attempts to deal in dramatic terms with his parental family culminating in his greatest play, Long Day's Journey Into Night. One of the essays speaks for those who are critical of O'Neill's work, and the volume concludes with an essay on O'Neill criticism containing a select bibliography of full-length studies of the playwright's work.
