Source: Wikipedia Ambrose Everett Burnside (May 23, 1824 – September 13, 1881) was an American soldier, railroad executive, inventor, industrialist, and politician from Rhode Island, serving as governor and a U.S. Senator. As a Union Army general in the American Civil War, he conducted successful campaigns in North Carolina and East Tennessee but was defeated in the disastrous Battle of Fredericksburg and Battle of the Crater. His distinctive style of facial hair is now known as sideburns, derived from his last name.
