Céline: A Biography (French: La Vie de Céline , "the life of Céline") is a 1988 book by the French writer Frédéric Vitoux, on the author Louis-Ferdinand Céline.
 It was published in English in 1992.
Tales from the Vienna Woods (1931) is the most famous play by Austro-Hungarian writer Ödön von Horváth (1901–1938).
 It was premièred in Berlin in 1931 and has been filmed several times.
 Before the première, the German writer and playwright, Carl Zuckmayer nominated the play for the Kleist Prize, which it won, the most significant literary award of the Weimar Republic.
 The play's title is a reference to the waltz, Tales from the Vienna Woods by Johann Strauss II.
 Horvarth's play premièred at the Deutsches Theatre, Berlin.
 Written in the late 1920s during the period of catastrophic unemployment and the Great Depression, the play is a key work of modern drama, described by Erich Kaestner as "a Viennese folk play accompanied by Viennese folk songs".
 It is a bitter satire about the mendacity and brutality of the petite-bourgeoisie, named ironically after the forested highlands near the Austrian capital that are so idealised in the waltz.
 In the play, Viennese 'Gemütlichkeit' or 'coziness' becomes a hollow phrase; the tragic, brutal story of the sweet girl Marianne and the deeply conventional butcher Oskar reflects the hardships and anxieties of the late 1920s during the global economic crisis.
North (French: Nord ) is a 1960 novel by the French writer Louis-Ferdinand Céline.
 The story is based on Céline's escape from France to Denmark after the invasion of Normandy, after he had been associated with the Vichy regime.
 It is the second published part, although chronologically the first, in a trilogy about these experiences; it was preceded by "Castle to Castle" from 1957, and followed by "Rigadoon", published posthumously in 1969.
 It was the last book Céline published during his lifetime.
Figaro lässt sich scheiden, op.40, ("Figaro Gets Divorced") is an opera in two acts by Giselher Klebe based on the comedy of the same name by Ödön von Horváth.
 Klebe also wrote the libretto for this work.
Born in Vienna, Schörg first trained for the profession of typist.
 In 1937, at the age of 23, she won a beauty contest and became " Queen of Danube ".
 That same year she made her stage debut in Ostrava at the Antonín Dvořák Theatre in the world premiere of Ödön von Horváth's play "Der jüngste Tag".
 She spent the next two years performing at that theatre, and at theatres in Karlovy Vary, Ostrava, Marienbad, and Vienna (Theater in der Josefstadt).
 In 1939 she joined the opera house in Aussig (now Usti nad Labem) where she became popular as a performer in operettas.
 She made her professional opera debut at that house as Hannerl in Heinrich Berté's arrangement of Franz Schubert's "Das Dreimäderlhaus".
Cannon-Fodder (French: Casse-pipe ) is an unfinished novel by the French writer Louis-Ferdinand Céline.
 The largely autobiographical narrative is set before World War II, and roughly continues where Céline's 1936 novel "Death on Credit" ended.
 Much of the novel disappeared in 1944.
 Surviving fragments have been published from 1948 and onward, the main part in book form in 1949.
Edmund Josef von Horváth (9 December 1901 Sušak, Rijeka, then in Austria–Hungary, now in Croatia – 1 June 1938 Paris) was a German-writing Austro-Hungarian-born playwright and novelist.
 He preferred the Hungarian version of his first name and published as Ödön von Horváth.
