John Anthony Spencer Clunn MBE (10 May 1946 – 3 August 2014) was a major in the British Army, and an amateur archaeologist who discovered the main site of the Battle of the Teutoburg Forest at Kalkriese Hill.
[3] Appointed Member of the Order of the British Empire in the 1996 New Year Honours,[4][5] he retired from the army on 4 April 1996.
Schlüter's recommendation was based upon a study of maps and the 19th-century historian Theodor Mommsen's proposal that the Kalkriese area was a likely location of the battle which took place in 9 C.E.
[10][14][15][16] On the basis of Clunn's findings, Schlüter began a comprehensive excavation of the site in 1989,[8][10] later directed by Susanne Wilbers-Rost.
The coins he discovered have made it possible to reconstruct the route taken by the Roman legionaries under Varus and to determine where they were ambushed and massacred.
