The Internationale Ausstellung neuer Theatertechnik (International Exhibition of New Theatre Technique) was an avant-garde event embracing theatre and cinema organised by Friedrich Kiesler in Vienna during the Musik- und Theaterfestes der Stadt Wien.[1]
The opening ceremony was interrupted by Jacob L. Moreno, who accused Kiesler of plagiarism as regards the "space stage" which Moreno claimed was derived from his "Stegreiftheater" (Theatre of Spontaneity).[2]
The event included The Sword of Attila, a play by Alma Mahler and Ernst Fischer, a lecture by Karl Kraus and world premieres by Arthur Schnitzler and Arnold Schönberg.[3]
