Golden Rectangle
Theo van Doesburg (1883 - 1931) was a Dutch artist, practicing in painting, writing, poetry and architecture. He is best known as the founder and leader of De Stijl.

De Stijl, also known as neoplasticism, was a Dutch artistic movement founded in 1917. Proponents of De Stijl sought to express a new utopian ideal of spiritual harmony and order. They advocated pure abstraction and universality by a reduction to the essentials of form and color; they simplified visual compositions to the vertical and horizontal directions, and used only primary colors along with black and white.
