Theatre critics and historians generally acknowledge a movement toward realism in nineteenth century American dramaturgy and cite Augustin Daly, Bronson Howard, William Gillette, and James A. Herne as innovators in the development of American realism. Steele Mackaye, however, is rarely included as a significant part of this movement; although his theatrical inventions are hailed as far-sighted and innovative, his plays are usually dismissed as unworthy of consideration, as conventional melodramas reflecting the fashion of the day. The close study of Mackaye's plays, however, reveals that he was in the vanguard of the movement toward realism.
