A career Army officer and influential military thinker, he helped shape how the U.S. Army studied tactics and prepared its officers at the turn of the twentieth century. His writing grew out of real frontier service, teaching, and high-level staff work.

by Arthur L. (Arthur Lockwood) Wagner
Born in Ottawa, Illinois, in 1853, Arthur Lockwood Wagner graduated from West Point and went on to serve in the U.S. Army during the Indian Wars. He later became known not just as an officer in the field, but as a serious student of military science.
Wagner taught and wrote extensively on tactics, military operations, and the training of officers. He served as an instructor at the Infantry and Cavalry School at Fort Leavenworth and became one of the best-known military educators of his era, with his books helping to professionalize the Army before the major changes of the early twentieth century.
His career also included staff service during the Spanish-American War and in the Philippines. He died in 1905, the same year he was advanced to brigadier general, and is remembered as an important reform-minded voice in the development of modern American military education.
