Bertolt Brecht was a 20th century German playwright, poet, and theatre director who made important contributions to dramaturgy. He was born in 1898 in Augsburg, Germany and wrote plays such as The Threepenny Opera and Mother Courage and Her Children. Due to the rise of the Nazis, Brecht went into exile in 1933, living in various countries until emigrating to the United States in 1941. He left behind an extensive literary archive of over 500,000 documents now housed in Berlin. Brecht explored political and social themes in his epic theatre works which aimed to distance audiences and provoke thought rather than elicit emotion.
