If it is true that the pen is mightier than the sword and that one picture is worth a thousand words, Thomas Nast must certainly rank as one of the most influential personalities in nineteenth century American history. His pen, dipped in satire, aroused an apathetic, disinterested, and uninformed public to indignation and action more than once. Thomas Nast, Political Cartoonist by J. Chal Vinson, University of Georgia Press, 1967.
