Charles W. Bullard was an American criminal. Known as Piano Charley, he became a notorious safecracker. His name derived from his skill as a musician. One of his criminal partnerships was with Adam Worth. In 1869, together with Fredericka Mandelbaum and others, Worth helped Bullard to escape from prison where he was serving a sentence for stealing $100,000 worth of goods from the Hudson River Railway Express. For the escape, Mandelbaum and her associates rented an office across the street from the prison and tunnelled into Bullard's cell, bribing two guards to keep them quiet.
