5. Ambrose Everett Burnside
Position held: Rhode Island Senator
Facial hair style: Stachburns
Ambrose Everett Burnside earned his place in history through his heroics during the Civil War, his political career, and, most importantly, his legendary facial hair, which inspired the term "sideburns." Burnside’s thick mutton chops didn’t just stop on the side of his face either—they actually connected to his mustache. That's facial hair engineering at its finest.
