The 1851 census showed the presence of 12,245 Germans in Paris, the vast majority of whom were craftsmen. The "Adressbuch 1854" project, carried out at the German Historical Institute between 2002 and 2006, made use of a work identified in the holdings of the library of the city of Paris. Some 4,700 addresses were listed in a directory that can still be consulted in the archives. The project consisted of integrating the entries in the book into a database that could be consulted online. The dataset focuses on the noble persons who were listed in the book. Their occupation, location and rank. For some, the legion of honor is indicated.
