In addition to serving as the 24th governor of Ohio, Dennison was U.S. Postmaster in the cabinet of America's most famous beard-wearer, Abraham Lincoln. Think he grew his own under-the-chin warmer as a way of sucking up?

That way, he'd really impress the ladies when he showed it off at the end of the night.
