Ambrose E. Burnside was born on May 23, 1824, in Liberty, Indiana. A Union general during the Civil War, Burnside became known for his warm personality, uneven battlefield record, and unforgettable facial hair. His distinctive whiskers — thick side tufts connected to a mustache, with a clean‑shaven chin — became so iconic that Americans eventually flipped his name around to describe the style: “sideburns.” After the war, Burnside served as Governor of Rhode Island and later as a U.S. Senator, remaining a popular public figure long after leaving the battlefield.
