De Stijl Artist. De Stijl, Dutch for The Style, also known as Neoplasticism, was a Dutch art movement founded in 1917 in Leiden. De Stijl consisted of artists and architects. In a narrower sense, the term De Stijl is used to refer to a body of work from 1917 to 1931 founded in the Netherlands. Proponents of De Stijl advocated pure abstraction and universality by a reduction to the essentials of form and colour; they simplified visual compositions to vertical and horizontal, using only black, white and primary colors. De Stijl is also the name of a journal that was published by the Dutch painter, designer, writer, and critic Theo van Doesburg that served to propagate the group's theories. Along with van Doesburg, the group's principal members were the painters Piet Mondrian, Vilmos Huszár, Bart van der Leck, and the architects Gerrit Rietveld, Robert van 't Hoff, and J. J. P. Oud. The artistic philosophy that formed a basis for the group's work is known as Neoplasticism, the new plastic art. According to Theo van Doesburg in the introduction of the magazine De Stijl 1917 no.1, the De Stijl-movement was a reaction to the Modern Baroque of the Amsterdam School movement with the magazine Wendingen. Mondrian sets forth the delimitations of Neoplasticism in his essay Neo-Plasticism in Pictorial Art. He writes, this new plastic idea will ignore the particulars of appearance, that is to say, natural form and colour. On the contrary, it should find its expression in the abstraction of form and colour, that is to say, in the straight line and the clearly defined primary colour. With these constraints, his art allows only primary colours and non-colours, only squares and rectangles, only straight and horizontal or vertical lines. The De Stijl movement posited the fundamental principle of the geometry of the straight line, the square, and the rectangle, combined with a strong asymmetricality; the predominant use of pure primary colors with black and white; and the relationship between positive and negative elements in an arrangement of non-objective forms and lines. The plastic vision of De Stijl artists, also called Neo-Plasticism, saw itself as reaching beyond the changing appearance of natural things to bring an audience into intimate contact with an immutable core of reality, a reality that was not so much a visible fact as an underlying spiritual vision. In general, De Stijl proposed ultimate simplicity and abstraction, both in architecture and painting, by using only straight horizontal and vertical lines and rectangular forms. Furthermore, their formal vocabulary was limited to the primary colours, red, yellow, and blue, and the three primary values, black, white, and grey. The works avoided symmetry and attained aesthetic balance by the use of opposition. This element of the movement embodies the second meaning of stijl: a post, jamb or support; this is best exemplified by the construction of crossing joints, most commonly seen in carpentry. In many of the group's three-dimensional works, vertical and horizontal lines are positioned in layers or planes that do not intersect, thereby allowing each element to exist independently and unobstructed by other elements. This feature can be found in the Rietveld Schröder House and the Red and Blue Chair. De Stijl was influenced by Cubist painting as well as by the mysticism and the ideas about ideal geometric forms in the neoplatonic philosophy of mathematician M. H. J. Schoenmaekers. The De Stijl movement was also influenced by Neopositivism. The works of De Stijl would influence the Bauhaus style and the international style of architecture as well as clothing and interior design. However, it did not follow the general guidelines of an -ism, nor did it adhere to the principles of art schools like the Bauhaus; it was a collective project, a joint enterprise. In music, De Stijl was an influence only on the work of composer Jakob van Domselaer, a close friend of Mondrian. Between 1913 and 1916, he composed his Proeven van Stijlkunst, inspired mainly by Mondrian's paintings. This minimalistic, and, at the time, revolutionary, music defined horizontal and vertical musical elements and aimed at balancing those two principles. Van Domselaer was relatively unknown in his lifetime, and did not play a significant role within De Stijl.
