Mouth of Wisconsin River

Art Historical Context

Henry P. Bosse’s *Mouth of Wisconsin River* (1885) captures the serene confluence of the Wisconsin and Mississippi Rivers in a striking cyanotype. Created using a photographic process that produces rich Prussian blue tones, the oval image evokes both scientific documentation and poetic atmosphere. Bosse, a German-born civil engineer and photographer, worked for the U.S. Army Corps of Engineers, recording the Upper Mississippi River system during a period of rapid industrial expansion and river navigation improvements. The choice of cyanotype—a medium often associated with architectural blueprints—lends the landscape an otherworldly quality, transforming the everyday river scene into an artistic study of light, water, and horizon. Measuring roughly 10 by 13 inches within its larger sheet, the photograph balances precise topographical detail with the soft, monochromatic beauty typical of the process. Acquired by the Metropolitan Museum of Art in 2015, this work highlights Bosse’s rare contribution to nineteenth-century American photography. It invites viewers to consider how early photographic techniques documented the nation’s waterways while revealing their quiet majesty.
