(1831–94) army officer and ethnologist, born in Wilkes-Barre, Pennsylvania. His studies of American-Indian sign language and pictographs began while he was stationed in Dakota Territory (1876). Mallery had been commissioned an officer in the regular army after the Civil War, during which he had served with volunteer Pennsylvania infantry and cavalry units. In 1877 Mallery was assigned to the U.S. Geographical and Geological Survey to study Indian drawings. He retired from the army in 1879 to work as a civilian on the staff of the Bureau of Ethnology.
