Eugen Berthold Friedrich Brecht, known professionally as Bertolt Brecht, was a German theatre practitioner, playwright, and poet. Living in Munich during the Weimar Republic, he had his first successes with theatre plays, whose themes were often influenced by his Marxist thought. He was the main proponent of the genre named epic theatre (which he preferred to call "dialectical theatre"). During the Nazi period and World War II he lived in exile, first in Scandinavia and then in the United States. Returning to East Berlin after the war, he established the theatre company Berliner Ensemble with his wife and long-time collaborator, actress Helene Weigel.
