Dutch painter, an important contributor to the De Stijl art movement (neoplasticism: pure abstraction and universality by a reduction to the essentials of form and colour). He is best known for his non-representational paintings (which he called compositions), consisting of rectangular forms of red, yellow, blue, or black.

Composition with Yellow, Blue and Red

In Switzerland you often see concrete trucks with a “Mondrian” paint (he would probably have liked that), so to me Mondrian equals concrete truck!

He has been variously associated with expressionism, cubism and surrealism but his pictures are difficult to classify. They often have a fragile child-like quality to them, and are usually on a small scale. They frequently allude to poetry, music and dreams and sometimes include words or musical notation. The later works are distinguished by spidery hieroglyph-like symbols.
