Piet Zwart (1885-1977), a Rotterdam-based designer and typographer, began his career working in the tradition of the Arts and Crafts movement, but radically reoriented his work in 1917 under the influence of the avante-garde De Stijl group. He was a member of the Circle of New Advertising Designers, a group of designers founded by Schwitters, who shared similar experimental interests. In addition to his commercial design projects, Zwart was also involved in leftist politics and the Dutch worker-photography movement.
