In the 1860s the firm published foreign-language materials including instruction manuals and reprints of literary works by Hans Christian Andersen, Francesco Dall'Ongaro, Gustav zu Putlitz, Carl Theodor Körner and others; translations of literary works (such as Dante's Inferno); and some English-language works.
After the death of G.H. De Vries in 1870, the firm continued for some time, and then was acquired by Carl Schoenhof, one of the firm's employees.
