Ranulph Bacon

Lieutenant-Colonel Sir Ranulph Robert Maunsell Bacon QPM (6 August 1906 – 30 March 1988) was a British police officer.

Bacon was born in Westgate-on-Sea, Kent, and educated at Tonbridge School and Queens' College, Cambridge. He joined the Metropolitan Police as a Constable in 1928 and was selected for Hendon Police College in 1934, passing out with the Baton of Honour. In May 1940 he was commissioned into the British Army as a Provost Marshal on the General List. By December 1941, when he was mentioned in despatches for his service in the Western Desert, he held the local rank of Major, although his substantive rank was Lieutenant. He was later promoted Lieutenant-Colonel and in 1942 was appointed Deputy Provost Marshal of the Ninth Army.

In November 1943 he was seconded to the Colonial Police Service as Deputy Inspector-General of the Ceylon Police, and was promoted Inspector-General in 1944. His Deputy Inspector-General was John Waldron, another Hendon graduate who was later to succeed him as both Assistant Commissioner "A" and Deputy Commissioner of the Metropolitan Police.

In 1947 he returned to Britain as Chief Constable of the Devon County Constabulary, and held the post until his appointment as Assistant Commissioner "A" (Operations and Administration) of the Metropolitan Police on 1 November 1961. He was awarded the King's Police and Fire Services Medal in the 1953 New Year Honours. In 1963, he was appointed Assistant Commissioner "C" (Crime), in charge of the Criminal Investigation Department. At a press conference on 31 December 1964, he urged the public to "have a go" if they saw an armed robbery taking place, which was criticised as irresponsible by many. He was knighted in the 1966 New Year Honours.

In 1966 he briefly served as Deputy Commissioner, from 8 April to his retirement in October.
