Stetson, John B.
John Batterson Stetson was born in East Orange, New Jersey in 1830. His father, Stephen Stetson, was a successful hatter and taught his children the trade. Stetson developed tuberculosis as a young man, and moved west hoping to recover. He first settled in St. Joseph, Missouri, and later moved west following the Gold Rush to California, before finally returning to Philadelphia to try his hand at the hat manufacturing trade.

Stetson found the eastern hat market difficult, and so turned his attention to the Westerners… marketing hats based upon styles he had seen and developed during his own travels. By 1872, he was also marketing dress hats in his own catalog, and by the turn of the twentieth century he had the world’s largest hat factory. Although John Stetson died in 1906, his company followed men’s fashions into the twentieth century, manufacturing top hats, bowlers, homburgs, fedoras, and trilbys, as well as straw hats in both western and dress styles.
By the early 1950s, there were fewer dress hat wearers, and Stetson has since focused primarily on their western hats.
