Pop culture assigns the creation of the Western hat to John B. Stetson in 1865. The historical record tells a more pragmatic story of reverse engineering.
During an expedition to Colorado in the early 1860s to treat his tuberculosis, Stetson observed Mexican ranch hands, indigenous hunters, and Anglo prospectors struggling against blinding UV exposure and windstorms. The prospectors' felt derbies offered zero sun defense. Stetson took note of the local vaqueros, who wore thick, water-shedding beaver-felt sombreros with broad rims and rounded crowns.
Using skills learned from his father, an East Coast hatter, Stetson created his famous Boss of the Plains hat in 1865. It featured a four-inch crown, a four-inch flat brim, and was crafted from fine beaver fur felt. It was lightweight, remarkably waterproof, and could carry water from a creek without disintegrating.
Stetson did not engineer this design from thin air. He manufactured a commercial, industrialized version of the hats Mexican frontiersmen had produced by hand for over a century. Marketed aggressively to Anglo cowboys riding the Chisholm Trail, the Boss of the Plains capitalized on an existing Mexican innovation, packaged it for Eastern capital, and secured the patent footprint in American historical lore.
