Piet Mondrian (1872-1944) was a Dutch painter most famous for a style of art he called neoplasticism. His best known work involves a black on white grid filled in with the primary colors red, yellow, and blue to simplify his subject matter to a fundamental level. This ultra-abstract interpretation was part of the basic idea behind the De Stijl movement, of which Mondrian was a founding member. His work was essential to the growth of modern art and is some of the most recognizable art in modern history.
