Das neue Adam-Ries-Nachfahrenbuch

Das neue Adam-Ries-Nachfahrenbuch, compiled by Wolfgang Lorenz, serves as an extensive genealogical record dedicated to the descendants of the famed 16th-century German mathematician Adam Ries. Published in the late 20th century, the volume was created to document the widespread familial lineage that branched out from the mathematician, whose pedagogical works on arithmetic became foundational to German mathematical education during the Renaissance.

The design and content of the work are rooted in the tradition of German local and familial history research, commonly known as Heimatforschung. Lorenz focused on systematically organizing baptismal, marriage, and death records to bridge the gap between the historical figure of Adam Ries and his modern-day relatives. While primarily an academic and genealogical resource, it is regarded by historians and hobbyists alike as a significant effort to preserve the legacy of a man whose influence on Western numeracy remains deeply embedded in the cultural heritage of the Erzgebirge region.
