De Stijl means “The Style.” It’s the name of both a Dutch art movement and the magazine that championed its theories. Founded in 1917 by artists and architects, the movement counted Theo van Doesburg, Piet Mondrian, Vilmos Huszár, Bart van der Leck, Gerrit Rietveld, Robert van ‘t Hoff, and J. J. P. Oud among its members. Mondrian was the oldest of them, and in his essay “Neo-Plasticism in Pictorial Art” he set out their philosophy: “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.” The rectilinear modernism and kinetic power of De Stijl artists, and Mondrian in particular, is the subject of this much-awaited exhibition. —L.J.
