Pieter Cornelis Mondriaan (Dutch: [ˈpitər kɔrˈneːlɪs ˈmɔndrijaːn]; 7 March 1872 – 1 February 1944), known after 1906 as Piet Mondrian (/piːt ˈmɒndriɑːn/, US also /- ˈmɔːn-/, Dutch: [pit ˈmɔndrijɑn]), was a Dutch painter and art theoretician who is regarded as one of the greatest artists of the 20th century. He was one of the pioneers of 20th-century abstract art, as he changed his artistic direction from figurative painting to an increasingly abstract style, until he reached a point where his artistic vocabulary was reduced to simple geometric elements.
