by Herbert Eugene Bolton, Thomas Maitland Marshall
Born in 1876 and active as a historian in the early 20th century, Thomas Maitland Marshall wrote extensively about American history, with a strong focus on the Southwest, borderlands, and the colonial era. Surviving bibliographic records credit him with works such as A History of the Western Boundary of the Louisiana Purchase, 1819–1841, Diplomatic Relations of Texas and the United States, 1839–1843, and studies of Colorado history.
His published work shows a scholar interested in how regions were shaped by diplomacy, expansion, and local records. He also wrote American History and collaborated with Herbert Eugene Bolton on The Colonization of North America, 1492–1783, linking him to a broader effort to explain North American history in a readable, structured way.
Records also connect him with the University of Colorado, including The University of Colorado in War Time and Early Records of Gilpin County, Colorado, 1859–1861. He died in 1936, leaving behind a body of work that still speaks to readers interested in western history, state-building, and the documentary foundations of the American past.
