William Marcy “Boss” Tweed – 1823-1878
Boss Tweed was a powerful ring leader for New York City Democrats known then as Tammany Hall. Using his position as city supervisor, he appointed cronies and the party faithful, creating a thoroughly corrupt city government known as the “Tweed ring.” The most famous of the 19th century urban “bosses,” Tweed was exposed in the satiric cartoons of Thomas Nast and was ultimately tried and convicted on charges of forgery and larceny.
