No. 88. Wingdams below Winona, Minnesota

Art Historical Context

In the late 19th century, America pushed westward and commerce boomed along its mighty rivers, the Mississippi became a focal point for engineering ingenuity. Henry P. Bosse's *No. 88. Wingdams belowona, Minnesota* (1889), a crisp cyanotype print, captures one such innovation: wingdams—temporary wooden barriers extending from the riverbanks to narrow the channel, accelerate water flow, and scour silt from the bed. Commissioned by the U.S. Army Corps of Engineers, where Bosse served as a photographer and draftsman, this image documents the laborious efforts to make the Upper Mississippi navigable for steamboats hauling goods to growing Midwestern towns like Winona. Cyanotype, the medium here, was a pioneering photographic process invented in 1842, yielding distinctive blue-toned "blueprints" that were affordable, light-sensitive, and ideal for reproducible technical documentation. Bosse's precise composition highlights the stark geometry of these structures against the river's expanse, blending utilitarian record-keeping with an almost abstract beauty. Housed in The Metropolitan Museum of Art's Photographs department, this 14½ × 17⅛-inch sheet offers a window into an era when human ambition reshaped nature's course, underscoring the river's vital role in America's industrial expansion.

Henry P. Bosse · 1844–1893

Henry Peter Bosse was born in 1844 in Sonneberg, Prussia (now Germany), and immigrated to the United States around 1870. He settled in the Midwest and joined the U.S. Army Corps of Engineers in 1874 as a draftsman. By the mid-1880s he had risen to chief draftsman in the Rock Island, Illinois, district, where he remained for the rest of his career. His dual expertise in engineering and visual docum...
