Bertolt Brecht has been perceived as an ardent proponent of social change, an avid advocate of a just world that he defined in terms of socialism, and an adamant foe of capitalism for whose demise he hoped. He is justly regarded as one of the great innovators of theater theory and practice in the 20th century, and his influence has extended to Latin America and Asia. This reference book surveys Brecht's enormous contribution to world drama. Chapters by expert contributors assess his dramatic innovations, his poetry and prose, and topics of special interest to Brecht studies.
