author
1871–1938
A German historian and editor remembered for careful archival work, he helped shape how modern readers approach Frederick the Great and other figures from eighteenth-century Prussia. His books and document-based studies suggest a scholar more interested in evidence than legend.

by Gustav Berthold Volz
Born in 1871 and dying in 1938, Gustav Berthold Volz is listed in the German National Biography as a historian. Records in the German Digital Library connect him with a substantial body of historical writing and editing, especially on Frederick the Great and related Prussian subjects.
The works associated with him point to a strongly source-driven approach. Titles linked to his name include studies of Frederick the Great, work on Trenck, and other document-based publications, suggesting that he specialized in presenting historical figures through letters, records, and contemporary testimony rather than broad popular retellings.
That makes him the kind of author who can appeal to listeners interested in serious history: patient, archival, and closely tied to the original materials. Some biographical details are not easy to confirm from the sources I found, so this overview stays focused on the parts of his career that are clearly documented.
