In 1874 German-born and -trained lithographer Theodore Leonhardt (1818-1877) entered into partnership with his son Arno (1850-1909) after over twenty years in the Philadelphia lithographic trade. Leonhardt, a producer of certificates, bonds, checks, diplomas, cards, letterheads, and labels continued to specialize in bank and mercantile lithography after his son joined him in managing the business. The partners issued several certificates reflective of their German roots, including works for organizations in which Arno was active, such as the Junger Mannerchor. The firm, which promoted the elder Leonhardt’s twenty-five years in the business and the firm’s role in the Centennial Exhibition of 1876, operated until around 1960 under the proprietorship of Arno’s sons.
