František Kupka (September 23, 1871 – June 24, 1957), (also known as Frank Kupka or François Kupka), was a Czech painter and graphic artist. He was a pioneer and co-founder of the early phases of the abstract art movement and Orphic cubism (Orphism). Kupka's abstract works arose from a base of realism, but later evolved into pure abstract art. František Kupka was born in Opočno, eastern Bohemia (now Czech Republic) in 1871. From 1889 to 1892, he studied at the Academy of Fine Arts in Prague. At this time, he painted historical and patriotic themes. Kupka enrolled at the Academy of Fine Arts in Vienna, where he concentrated on symbolic and allegorical subjects. He was influenced by the painter and social reformer Karl Wilhelm Diefenbach (1851–1913) and his naturistic life-style. Kupka exhibited at the Kunstverein, Vienna, in 1894. His involvement with theosophy and Eastern philosophy dates from this period. By spring 1894, Kupka had settled in Paris; there he attended the Académie Julian briefly and then studied with Jean-Pierre Laurens at the École des Beaux-Arts.
Kupka worked as an illustrator of books and posters and, during his early years in Paris, became known for his satirical drawings for newspapers and magazines. In 1906, he settled in Puteaux, a suburb of Paris, and that same year exhibited for the first time at the Salon d'Automne. Kupka was deeply impressed by the first Futurist Manifesto, published in 1909 in Le Figaro. Kupka's 1909 painting Piano Keyboard/Lake marked a break in his representational style. His work became increasingly abstract around 1910–11, reflecting his theories of motion, color, and the relationship between music and painting (orphism). In 1911, he attended meetings of the Puteaux Group (Section d'Or). In 1912, he exhibited at the Salon des Indépendants in the Cubist room, although he did not wish to be identified with any movement. Creation in the Plastic Arts, a book Kupka completed in 1913, was published in Prague in 1923. In 1931, he was a founding member of Abstraction-Création. In 1936, his work was included in the exhibition Cubism and Abstract Art at the Museum of Modern Art in New York City, and in an important show with another Czech painter Alphonse Mucha at the Jeu de Paume in Paris. A retrospective of his work took place at the Galerie Mánes in Prague in 1946. The same year, Kupka participated in the Salon des Réalités Nouvelles, where he continued to exhibit regularly until his death. During the early 1950s, he gained general recognition and had several solo shows in New York. Between 1919 and 1938 Kupka was financially supported by his good friend, art collector and industrialist Jindřich Waldes who accumulated a substantial collection of his art. Kupka died in 1957 in Puteaux, France.
Kupka had a strong interest in color theory. His decadent 1907 self-portrait The Yellow Scale prefigures his abstract emphasis on color. Around 1910 he began developing his own color wheels, adapting a format previously explored by Sir Isaac Newton and Hermann von Helmholtz. This work in turn led Kupka to execute a series of paintings he called "Discs of Newton" (1911–12). Kupka was interested in freeing colors from descriptive associations. His work in this area is thought to have influenced other artists like Robert Delaunay.
