Sir Kenneth Mackenzie Douglas, 1st Baronet

Lieutenant-General Sir Kenneth MacKenzie Douglas, 1st Baronet (1754–1833), born Kenneth MacKenzie, was the first baronet of the Douglas of Glenbervie, Kincardine Baronetcy (second creation). He was created baronet in 1831.

Born as Kenneth MacKenzie in Dundee in 1754, his father was Kenneth Mackenzie, of Kilcoy, Ross-shire, and his mother Janet, a daughter of Sir Robert Douglas, 6th Baronet of Glenbervie (first creation).

He was commissioned as an ensign in the 33rd Foot in 1767, and was promoted lieutenant in 1775. MacKenzie transferred to the 14th Foot in 1783. He served in Guernsey, the West Indies, Flanders, Gibraltar, and Egypt. He joined the 90th Foot in 1794, when, under Thomas Graham, (later Lord Lynedoch), he trained light company troops. On the death of Lieutenant-Colonel Ogilvie of the 44th Foot, Mackenzie transferred to that regiment, taking command.

Following a decision by the British Army to train some line regiments in light infantry techniques, Sir John Moore, a proponent of the light infantry model, offered his own regiment of line infantry, the 52nd (Oxfordshire) Regiment of Foot, for this training, at Shorncliffe Camp. Mackenzie was appointed lieutenant colonel of the 52nd. They formed a brigade with the 95th Rifles, and three line regiments. Much of the training was undertaken by Lieutenant-Colonel Kenneth MacKenzie, who devised many of the tactics of light infantry training, He was responsible for many of the drills and exercises of the "Shorncliffe System".
