Bohumil Kubišta (1884, Vlčkovice, Bohemia – 1918) was a Czech painter and art critic, one of the founders of Czech modern painting. He studied at the School of Applied Arts in Prague, but left in 1906 to study at the Reale Istituto di Belle Arti in Florence. He,Emil Filla, Antonín Procházka, and five others founded Osma (The Eight), an Expressionist-oriented group of artists.
Kubišta came to his individual expression gradually, at first he was influenced by the work of Vincent van Gogh and Paul Cézanne. He educated himself in philosophy and optics, and studied colour and the geometrical construction of painting.
Kubišta, like several other Czech artists of his generation, was strongly affected by the 1905 Edvard Munch exhibition in Prague. Together with Emil Filla he established the artistic group Osma in 1906 or 1907. He worked in an Expressionist style until 1910, and exchanged ideas with German painters in Die Brücke. He also developed visual ideas learned from the work of Cézanne. His later style (approximately from 1911) was strongly influenced by cubism and expressionism. Expressionist elements, particularly his use of color but also his subject matter, immediately distinguish Kubišta’s cubist work from that of founding Paris Cubists Picasso and Braque. He studied color theory, analyzing the harmonic and compositional principles of painters such as El Greco, Eugène Delacroix, Vincent van Gogh, and Edvard Munch. He also paid close attention to mathematical and geometric principles. Around 1911, he became acquainted with Jan Zrzavý and the artistic group Sursum.
