Lyonel Feininger (1871–1956) made these 14 nature studies of bridges between 1913 and 1920. He would use them as the basis for many fine paintings now held in the collections of museums like the Philadelphia Museum of Art and Museum Ludwig, Cologne, as well as private collections. They depict two bridges over the Ilm river in Weimar: the Sternbrücke (Star Bridge) and the Steinbrücke (Stone Bridge). Feininger would revisit these bridges, especially the Steinbrücke, in many of his later watercolors, drawings, woodcuts, and paintings.
