A member of the Dutch artistic movement De Stijl (The Style)—founded in 1917 by Piet Mondrian, Bart van der Leck, and Theo van Doesburg—the Belgian artist-architect-theorist Georges Vantongerloo spent his life working on architectural designs and compositional reflections. He achieved success early on, and displayed his models at the Musée des Arts Decoratifs in 1930. He often derived the carefully drawn lines of his abstract sculptures and paintings from mathematical equations, and was known for his simple interweaving of color and light. In a selective survey, 15 works on paper, and two important sculptures are on display. —E.C.
