The De Stijl (pr. duh-stayl') (or Dutch de Stijl) art movement - also known as "neoplasticism" - advocated pure abstraction and simplicity - form reduced to geometric shapes, and color to the primary colors, along with black and white.
Piet Mondrian (Dutch, 1872-1944), the group's most renowned artist, published a manifesto titled Neo-Plasticism in 1920. Painter Theo van Doesberg (Dutch, 1883-1931) published a journal named De Stijl from 1917 to 1928, spreading the theories of the group, which also included the painter George Vantongerloo (Belgian,1886-1965) and the architects J.J.P. Oud (1890-1963) and Gerrit Rietveld (Dutch, 1888-1965).
