author
1853–1928
A veteran and keen observer of travel, war, and adventure turned his own experiences into brisk, first-hand narratives. His books range from military history to vivid accounts of being caught abroad at the outbreak of World War I.

by George B. (George Burton) Thayer
George Burton Thayer (1853–1928) was an American writer best known for firsthand, experience-driven books. Library records identify him as the compiler of History of Company K, First Connecticut Volunteer Infantry, During the Spanish-American War (1899), a detailed regimental history rooted in the conflict of 1898.
He also wrote travel and memoir-style works, including In Hell—Shut In—At the Outbreak of the Great War, 1914, which suggests a talent for turning difficult, immediate events into readable narrative. Taken together, the surviving records show an author drawn to real-world action rather than fiction, with interests spanning military service, travel, and eyewitness storytelling.
Reliable biographical detail beyond his dates and published works is limited in the sources I could confirm, so the safest picture is of a late 19th- and early 20th-century American nonfiction author whose books preserve moments of war and travel from a personal point of view.
