Der Blaue Reiter in the context of "Henri Le Fauconnier"

Arnold Schoenberg or Schönberg (13 September 1874 – 13 July 1951) was an Austrian and American composer, music theorist, teacher and writer. He was among the first modernists who transformed the practice of harmony in 20th-century classical music, and a central element of his music was its use of motives as a means of coherence. He propounded concepts like developing variation, the emancipation of the dissonance, and the "unity of musical space".

Schoenberg's early works, like Verklärte Nacht (1899), represented a Brahmsian–Wagnerian synthesis on which he built. Mentoring Anton Webern and Alban Berg, he became the central figure of the Second Viennese School. They consorted with visual artists, published in Der Blaue Reiter, and wrote atonal, expressionist music, attracting fame and stirring debate. In his String Quartet No. 2 (1907–1908), Erwartung (1909), and Pierrot lunaire (1912), Schoenberg visited extremes of emotion; in self-portraits he emphasized his intense gaze. While working on Die Jakobsleiter (from 1914) and Moses und Aron (from 1923), Schoenberg confronted popular antisemitism by returning to Judaism and substantially developed his twelve-tone technique. He systematically interrelated all notes of the chromatic scale in his twelve-tone music, often exploiting combinatorial hexachords and sometimes admitting tonal elements.

Gabriele Münter (19 February 1877 – 19 May 1962) was a German expressionist painter who was at the forefront of the Munich avant-garde in the early 20th century. She studied and lived with the painter Wassily Kandinsky and was a founding member of the expressionist group Der Blaue Reiter.

Natalia Sergeevna Goncharova (Russian: Ната́лья Серге́евна Гончаро́ва, IPA: [nɐˈtalʲjə sʲɪrˈɡʲe(j)ɪvnə ɡənʲtɕɪˈrovə]; 3 July 1881 – 17 October 1962) was a Russian avant-garde artist, painter, costume designer, writer, illustrator, and set designer. Goncharova's lifelong partner was fellow Russian avant-garde artist Mikhail Larionov. She was a founding member of both the Jack of Diamonds (1909–1911), Moscow's first radical independent exhibiting group, the more radical Donkey's Tail (1912–1913), and with Larionov invented Rayonism (1912–1914). She was also a member of the German-based art movement Der Blaue Reiter. Born in Russia, she moved to Paris in 1921 and lived there until her death.

Her painting vastly influenced the avant-garde in Russia. Her exhibitions held in Moscow and St Petersburg (1913 and 1914) were the first promoting a "new" artist by an independent gallery. When it came to the pre-revolutionary period in Russia, where decorative painting and icons were a secure profession, her modern approach to rendering icons was both transgressive and problematic. She was one of the leading figures in the avant-garde in Russia and carried this influence with her to Paris.
