Ebenezer Tappen (September 11, 1815 - January 25, 1854) was an American engraver, lithographer, and publisher. Born in Manchester, Massachusetts, Tappen began working for a banknote and letterhead engraver in Boston in 1837. He worked as an engraver and lithographer from the same address, 39 State Street, until late 1848 or early 1849, when he formed a partnership with Ludowick Harrington Bradford (November 10, 1820 - December 13, 1885), another engraver and lithographer in Boston. The pair operated Tappen and Bradford until Tappen's death, when Bradford started his own firm called L.H. Bradford and Company.
