Known as the "Sage of Baltimore", he is regarded as one of the most influential American writers and prose stylists of the first half of the twentieth century. As a scholar Mencken is known for The American Language, a multi-volume study of how the English language is spoken in the United States. His satirical reporting on the Scopes trial, which he dubbed the "Monkey Trial", also earned him notoriety.
