Bertolt Brecht was a German playwright and poet born in 1898, known for his influential contributions to modern theater. He developed the concept of Epic Theatre, which aimed to provoke critical thinking in audiences rather than emotional engagement. Brecht's works often addressed social and political issues, encouraging viewers to question societal norms. Brecht's most famous plays include The Threepenny Opera and Mother Courage and Her Children. He also collaborated with composer Kurt Weill, creating memorable songs that enhanced his theatrical messages. Brecht's innovative techniques, such as the use of narration and breaking the fourth wall, have left a lasting impact on contemporary theater.
