Weimar Republic Berlin (1925–1933)

In 1923 Brecht's marriage to Zoff began to break down (though they did not divorce until 1927). Brecht had become involved with both Elisabeth Hauptmann and Helene Weigel. Brecht and Weigel's son, Stefan, was born in October 1924.

In his role as dramaturg, Brecht had much to stimulate him but little work of his own. Reinhardt staged Shaw 's Saint Joan, Goldoni 's Servant of Two Masters (with the improvisational approach of the commedia dell'arte in which the actors chatted with the prompter about their roles), and Pirandello 's Six Characters in Search of an Author in his group of Berlin theatres. A new version of Brecht's third play, now entitled Jungle: Decline of a Family, opened at the Deutsches Theater in October 1924, but was not a success.

In the asphalt city I'm at home. From the very start Provided with every last sacrament: With newspapers. And tobacco. And brandy To the end mistrustful, lazy and content.

Bertolt Brecht, "Of Poor BB"

At this time Brecht revised his important "transitional poem", "Of Poor BB". In 1925, his publishers provided him with Elisabeth Hauptmann as an assistant for the completion of his collection of poems, Devotions for the Home (Hauspostille, eventually published in January 1927). She continued to work with him after the publisher's commission ran out.

In 1925 in Mannheim the artistic exhibition Neue Sachlichkeit (" New Objectivity ") had given its name to the new post- Expressionist movement in the German arts. With little to do at the Deutsches Theater, Brecht began to develop his Man Equals Man project, which was to become the first product of "the 'Brecht collective'—that shifting group of friends and collaborators on whom he henceforward depended." This collaborative approach to artistic production, together with aspects of Brecht's writing and style of theatrical production, mark Brecht's work from this period as part of the Neue Sachlichkeit movement. The collective's work "mirrored the artistic climate of the middle 1920s", Willett and Manheim argue:

with their attitude of Neue Sachlichkeit (or New Matter-of-Factness), their stressing of the collectivity and downplaying of the individual, and their new cult of Anglo-Saxon imagery and sport. Together the "collective" would go to fights, not only absorbing their terminology and ethos (which permeates Man Equals Man) but also drawing those conclusions for the theatre as a whole which Brecht set down in his theoretical essay "Emphasis on Sport" and tried to realise by means of the harsh lighting, the boxing-ring stage and other anti-illusionistic devices that henceforward appeared in his own productions.

In 1925, Brecht also saw two films that had a significant influence on him: Chaplin 's The Gold Rush and Eisenstein 's Battleship Potemkin. Brecht had compared Valentin to Chaplin, and the two of them provided models for Galy Gay in Man Equals Man. Brecht later wrote that Chaplin "would in many ways come closer to the epic than to the dramatic theatre's requirements." They met several times during Brecht's time in the United States, and discussed Chaplin's Monsieur Verdoux project, which it is possible Brecht influenced.

In 1926 a series of short stories was published under Brecht's name, though Hauptmann was closely associated with writing them. Following the production of Man Equals Man in Darmstadt that year, Brecht began studying Marxism and socialism in earnest, under the supervision of Hauptmann. "When I read Marx 's Capital ", a note by Brecht reveals, "I understood my plays." Marx was, it continues, "the only spectator for my plays I'd ever come across." Inspired by the developments in USSR, Brecht wrote a number of agitprop plays, praising the bolshevik collectivism (replaceability of each member of the collective in Man Equals Man) and the Red Terror (The Decision).

For us, man portrayed on the stage is significant as a social function. It is not his relationship to himself, nor his relationship to God, but his relationship to society which is central. Whenever he appears, his class or social stratum appears with him. His moral, spiritual or sexual conflicts are conflicts with society.

Erwin Piscator, 1929.

In 1927 Brecht became part of the " dramaturgical collective" of Erwin Piscator 's first company, which was designed to tackle the problem of finding new plays for its "epic, political, confrontational, documentary theatre". Brecht collaborated with Piscator during the period of the latter's landmark productions, Hoppla, We're Alive! by Toller, Rasputin, The Adventures of the Good Soldier Schweik, and Konjunktur by Lania. Brecht's most significant contribution was to the adaptation of the unfinished episodic comic novel Schweik, which he later described as a "montage from the novel". The Piscator productions influenced Brecht's ideas about staging and design, and alerted him to the radical potentials offered to the " epic " playwright by the development of stage technology (particularly projections). What Brecht took from Piscator "is fairly plain, and he acknowledged it" Willett suggests:

The emphasis on Reason and didacticism, the sense that the new subject matter demanded a new dramatic form, the use of songs to interrupt and comment: all these are found in his notes and essays of the 1920s, and he bolstered them by citing such Piscatorial examples as the step-by-step narrative technique of Schweik and the oil interests handled in Konjunktur ('Petroleum resists the five-act form').

Brecht was struggling at the time with the question of how to dramatize the complex economic relationships of modern capitalism in his unfinished project Joe P. Fleischhacker (which Piscator's theatre announced in its programme for the 1927–28 season). It wasn't until his Saint Joan of the Stockyards (written between 1929 and 1931) that Brecht solved it. In 1928 he discussed with Piscator plans to stage Shakespeare 's Julius Caesar and Brecht's own Drums in the Night, but the productions did not materialize.

The year 1927 also saw the first collaboration between Brecht and the young composer Kurt Weill. Together they began to develop Brecht's Mahagonny project, along thematic lines of the biblical Cities of the Plain but rendered in terms of the Neue Sachlichkeit ' s Amerikanismus, which had informed Brecht's previous work. They produced The Little Mahagonny for a music festival in July, as what Weill called a "stylistic exercise" in preparation for the large-scale piece. From that point on Caspar Neher became an integral part of the collaborative effort, with words, music and visuals conceived in relation to one another from the start. The model for their mutual articulation lay in Brecht's newly formulated principle of the " separation of the elements ", which he first outlined in " The Modern Theatre Is the Epic Theatre " (1930). The principle, a variety of montage, proposed by-passing the "great struggle for supremacy between words, music and production" as Brecht put it, by showing each as self-contained, independent works of art that adopt attitudes towards one another.

In 1930 Brecht married Weigel; their daughter Barbara Brecht was born soon after the wedding. She also became an actress and would later share the copyrights of Brecht's work with her siblings.

Brecht formed a writing collective which became prolific and very influential. Elisabeth Hauptmann, Margarete Steffin, Emil Burri, Ruth Berlau and others worked with Brecht and produced the multiple teaching plays, which attempted to create a new dramaturgy for participants rather than passive audiences. These addressed themselves to the massive worker arts organisation that existed in Germany and Austria in the 1920s. So did Brecht's first great play, Saint Joan of the Stockyards, which attempts to portray the drama in financial transactions.

This collective adapted John Gay 's The Beggar's Opera, with Brecht's lyrics set to music by Kurt Weill. Retitled The Threepenny Opera (Die Dreigroschenoper) it was the biggest hit in Berlin of the 1920s and a renewing influence on the musical worldwide. One of its most famous lines underscored the hypocrisy of conventional morality imposed by the Church, working in conjunction with the established order, in the face of working-class hunger and deprivation:

The success of The Threepenny Opera was followed by the quickly thrown together Happy End. It was a personal and a commercial failure. At the time the book was purported to be by the mysterious Dorothy Lane (now known to be Elisabeth Hauptmann, Brecht's secretary and close collaborator). Brecht only claimed authorship of the song texts. Brecht would later use elements of Happy End as the germ for his Saint Joan of the Stockyards, a play that would never see the stage in Brecht's lifetime. Happy End' s score by Weill produced many Brecht/Weill hits like "Der Bilbao-Song" and "Surabaya-Jonny".

The masterpiece of the Brecht/Weill collaborations, Rise and Fall of the City of Mahagonny (Aufstieg und Fall der Stadt Mahagonny), caused an uproar when it premiered in 1930 in Leipzig, with Nazis in the audience protesting. The Mahagonny opera would premier later in Berlin in 1931 as a triumphant sensation.

Brecht spent the last years of the Weimar-era (1930–1933) in Berlin working with his "collective" on the Lehrstücke. These were a group of plays driven by morals, music and Brecht's budding epic theatre. The Lehrstücke often aimed at educating workers on Socialist issues. The Measures Taken (Die Massnahme) was scored by Hanns Eisler. In addition, Brecht worked on a script for a semi-documentary feature film about the human impact of mass unemployment, Kuhle Wampe (1932), which was directed by Slatan Dudow. This striking film is notable for its subversive humour, outstanding cinematography by Günther Krampf, and Hanns Eisler's dynamic musical contribution. It still provides a vivid insight into Berlin during the last years of the Weimar Republic.
