De Stijl is also the name of a journal that was published by the Dutch painter, designer, writer, and critic Theo van Doesburg (1883–1931) that served to propagate the group's theories. Next to van Doesburg, the group's principal members were the painters Piet Mondrian (1872–1944), Vilmos Huszár (1884–1960), and Bart van der Leck (1876–1958), and the architects Gerrit Rietveld (1888–1964), Robert van 't Hoff (1887–1979), and J. J. P. Oud (1890–1963). The artistic philosophy that formed a basis for the group's work is known as neoplasticism—the new plastic art (or Nieuwe Beelding in Dutch).
