author
Known today mainly for a handful of mid-20th-century adventure and working-life stories, this hard-to-find writer is best remembered for Bob Hazard, Dam Builder. The surviving record is sparse, which gives the work an old-library curiosity of its own.

by Carl Brandt
Project Gutenberg lists Carl Brandt as the author of Bob Hazard, Dam Builder, and Open Library also attributes that title to him along with a small number of other books, including Jerry King and Jerry King, timber cruiser.
Beyond those bibliographic records, reliable biographical details are limited. I couldn't confirm basic personal information such as birth and death dates from strong public sources, so this overview stays close to what can be verified: Brandt appears to have been a lesser-known author whose work centered on practical, work-driven, and adventure-flavored subjects.
Because the public record is so thin, Brandt is one of those authors known more through the books than through a well-documented life story. For readers, that can be part of the appeal: his work feels like a rediscovered shelf find from another era.
