"The year 1921 was of great importance for Weimar Bauhaus art-school and for the development of German art. In that year the Dutchman Theo van Doesburg came to Weimar as our guest. His activities were devoted to the new way of expression, which he brought in his work as a stimulus. Through his periodical De Stijl.. ..he made us acquainted with the work of 'De Stijl' artists in Holland. He zealously propagated the best foreign artists, who have acknowledged the expression of new spirit. His lectures illustrated with slides stimulated the younger generation which at that time was assembled at the Weimar Bauhaus. Many pupils accepted the doctrine of the new expression, which has its master in Van Doesburg. I have been an enthousiastic pupil of this master and I honour him as the herald and pathfinder of the new era."
