David James Cathcart King FSA (1913 – 29 September 1989)[1] was a British historian, archaeologist, and school-teacher.
While working as a teacher he perused his research in his free time, becoming "one of the leading authorities on the medieval castle".
[5] During the Second World War, King served in the Royal Artillery in the Middle East.
His time there encouraged his interest in military architecture,[1] and he went on to write papers about Krak des Chevaliers and the Citadel of Damascus in Syria.
[6][7] After the war, King worked at Walton Lodge Preparatory School in Bristol as a history teacher.
