d. 1951
Best known for a concise history of Wisconsin’s Native peoples, this little-documented writer left behind a work that has stayed in circulation through libraries, reprints, and audiobook editions.

by John M. Douglass
Very little biographical information about this author could be confirmed from reliable online sources. What is clear is that John M. Douglass is credited as the author of The Indians in Wisconsin's History, a short history published by the Milwaukee Public Museum in 1954.
The book surveys the lives and history of Native peoples in Wisconsin, from pre-European times through French, British, and U.S. rule. Modern library and archive records, along with public-domain audiobook listings, also note that Douglass died in 1951, which suggests the book appeared after his death.
Because so few dependable sources about his life are readily available online, it is safest to remember him through this surviving work and its continuing readership rather than through personal details that cannot be verified.
