František Kupka

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, but later evolved into pure abstract art. Provided by Wikipedia
