Great play, that introduced the word ""robot"" into English, looks to a future in which all workers are automatons. Their revolt when they acquire souls (i.e., when they gain the ability to hate) and the resulting catastrophe make for a powerful and deeply moving theatrical experience. ""It is murderous social satire, done in terms of the most hair-raising melodrama."" - Alexander Woolcott. ""As awe-inspiring as anything we have ever seen in the theatre."" - Heywood Broun. Paul Selver translation.
