by Carl Brandt
Very little biographical information about this author could be confirmed from readily available reliable sources during this search, so it is best to keep the picture simple. Carl Brandt is credited as the author of Bob Hazard, Dam Builder, an adventure novel that has been preserved by Project Gutenberg and later library and reprint catalogs.
The book follows a young man determined to become a civil engineer and centers on dam construction, which gives Brandt's work a practical, industrious tone alongside its adventure elements. That mix of aspiration, technical work, and youthful determination fits well with the boys' fiction of the early 1900s.
Because solid biographical records were not easy to verify, details about Brandt's life, dates, and broader career should be treated cautiously unless confirmed by stronger archival sources.
