De Stijl
Van Doesburg also knew J. J. P. Oud and the Hungarian artist Vilmos Huszár. In 1917 the cooperation of these artists, together with the poet Antony Kok, resulted in the founding of De Stijl. The young architect Gerrit Rietveld joined the group in 1918. At its height De Stijl had 100 members and the journal had a circulation of 300.
