Piet Mondrian
Mondrian was a contributor to the De Stijl art movement and group, which was founded by Theo van Doesburg. He evolved a non-representational form which he termed neoplasticism. This consisted of white ground, upon which he painted a grid of vertical and horizontal black lines and the three primary colors.
Mondrian's arrival in Paris from the Netherlands in 1911 marked the beginning of a period of profound change. He encountered experiments in Cubism - http://www.theartstory.org/artist-mondrian-piet.htm
Mondrian believed that art reflected the underlying spirituality of nature. He simplified the subjects of his paintings down to the most basic elements, in order to reveal the essence of the mystical energy in the balance of forces that governed nature and the universe.
