[edit] Assistants to the Commandant of the Marine Corps

Before the official title of "Assistant Commandant of the Marine Corps" was adopted in 1946 the title of the position was known as the Assistant to the Commandant and prior to 1918, only a billet "Duty in the office of the Commandant". No records exist prior to the outbreak of World War I about this position, possibly because the Commandant likely had only administrative staff and no deputy.^[2]

The first of the Assistants to the Commandant was Lieutenant Colonel Eli K. Cole who assumed the position April 29, 1911. From April 29, 1911 to October 16, l946 19 men were assigned to assist the commandant including 5 that eventually went on to become commandant themselves; John A. Lejeune, Wendell C. Neville, Ben H. Fuller, John H. Russell, Jr. and Alexander A. Vandegrift.^[2]
