Bowler

A hard, rounded hat with a narrow brim, typically black, worn formally by men.

Named after London hat makers Thomas and William Bowler in 1849, who created it for a customer who needed a low-profile hat for gamekeepers that wouldn't get knocked off by tree branches. The original order came from politician Edward Coke, who wanted a hat tough enough to protect his gamekeepers' heads from poachers' attacks. Ironically, it became the quintessential symbol of British gentlemen and city bankers rather than rural workers.
