David John Anthony Stone (born 1947) is an established military author and historian and a former British army officer. Most of his ten books on various aspects of military conflict have been written and published since he retired from active military duty in 2002, including several studies on the Prussian and German armies throughout the course of history: an area in which his particular expertise is today acknowledged both in the UK and abroad. He is a Member of the Society of Authors and of several other professional, literary and historical or heritage-related groups and organisations. He has maintained a close connection with the heritage and historical perspectives of his former regiment, serving from 2002 to 2015 as a senior trustee of what is today The Rifles (Berkshire and Wiltshire) Museum at Salisbury. He was elected a Fellow of the Chartered Management Institute in 1994 and a Member of the Institute of Directors in 2000. He is married and lives in Devon, England.
