b. 1879
Best known for helping record one of the most unusual American campaigns of World War I, this writer brought firsthand military experience to a vivid account of the fighting in North Russia. His work remains closely tied to the story of the Polar Bear Expedition.

Joel R. Moore, identified in library and archival records as Joel Roscoe Moore (born 1879), was an American army officer and writer associated with the American Expeditionary Force in North Russia during and just after World War I.
He is best known as a compiler and editor of The History of the American Expedition Fighting the Bolsheviki; Campaigning in North Russia 1918-1919, first published in 1920 with Harry H. Mead and Lewis E. Jahns. The book is a contemporary account of the so-called Polar Bear Expedition and has stayed in circulation through library collections and later reprints.
University of Michigan archival records describe him as a captain of Company M, 339th U.S. Infantry, and note that his papers include correspondence, citations, and photographs connected with that service. I found references to a studio portrait in those archives, but I could not confirm a directly usable image file for this page.
