František Kupka (23 September 1871 – 24 June 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 and heavy symbolism (under the viennese influence), but later evolved into pure abstract art.
