Teacher by training, Buchholz abandoned his job to become a professional artist in 1914 but only after WWI, in 1918, he could truly explore his style, focussing on abstract painting and starting the non-objective movement or Concrete Art. He exhibited at the Der Sturm gallery in Berlin and took part in the First Exhibition of Modern Art in Bucarest. In 1922 he met El Lissitzky and Moholy-Nagy, Schwitters, Höch, Hausmann and Hülsenbeck. He developed also an interest for architecture and wrote few texts and booklets about the constructivist principles. During ‘50s he restarted to paint and in 1964 he produced his screen prints Constant-Variables.
