Revolution in German Theatre 1900-1933 (Routledge Revivals) [PDF ebook] 

First published in 1981, this book represents the first work in English to give a comprehensive account of the revolutionary developments in German theatre from the decline of Naturalism through the Expressionist upheaval to the political theatre of Piscator and Brecht. Early productions of Kaiser’s From Morning till Midnight and Toller’s Transfiguration are presented as examples of Expressionism. A thorough analysis of Piscator’s Hoppla, Such is Life! And Brecht’s Man show the similarities and differences in political theatre. In addition, elements of stage-craft are examined — illustrated with tabulated information, an extensive chronology, and photographs and designs of productions.
