Blood and Iron

Sheenan, Perley Poore, and Robert Hobart Davis. "Blood and Iron." The Strand Magazine. Oct. 1917.

Unproduced short play, featuring a predecessor of K. Capek's robots, and what we would call a cyborg. The robot/cyborg created by a German scientist by replacing body parts on a man isn't totally mechanized, retains his humanity, and, appalled by the suffering caused by war, murders the Kaiser. Cited in Appendix to R. Willingham's Science Fiction and the Theatre, source here, and quoted.
