Henry Colville Montgomery Campbell (11 October 1887 – 26 December 1970) was a Church of England bishop. He was ordained in 1910 and served as vicar or rector in a number of London parishes before being consecrated as a bishop in 1940, holding, successively, the suffragan bishoprics of Willesden and Kensington and the diocesan bishoprics of Guildford and London until his retirement in 1961. Early life and ordained ministry Montgomery Campbell was the son of Sydney Montgomery Campbell, who was ordained as an Anglican priest in 1885 and became vicar of St John's, Hammersmith, and later of Midhurst and Banstead. The son was educated at Malvern College and Brasenose College, Oxford. After studying at Wells Theological College he was made deacon in December 1910 and ordained priest by Edward Talbot, Bishop of Winchester, at Holy Trinity Church, Guildford, on St Thomas's Day 1911 (21 December). His first appointment was a curacy at Alverstoke. In 1916 he married Joyce Mary, daughter of Norman Thicknesse, rector of St George's Hanover Square. After distinguished wartime service in which he received the Military Cross for bravery at Gallipoli, he served as vicar of West Hackney (1919–26) and Hornsey (1926–33). In the latter post he ran a centre for the unemployed in a building made available to him by the government. From 1929 to 1933 he also held the post of Rural Dean of Hornsey. In 1933, on Thicknesse's retirement, Montgomery Campbell was appointed to succeed him at St George's. Episcopal ministry Montgomery Campbell was appointed to the episcopate as the suffragan Bishop of Willesden in 1940; consecrated a bishop by Cosmo Lang, Archbishop of Canterbury, on 25 July 1940 at St Paul's Cathedral, and translated to be the Bishop of Kensington in 1942 (his appointment was announced on 13 March and he must have been translated by the time of his successor's consecration on 25 March). He became a diocesan bishop as Bishop of Guildford in 1949 — his election was confirmed on 23 November. His diocese was of quite recent creation, having been formed in 1927. The new cathedral by Edward Maufe was under construction, and the pro-cathedral, Holy Trinity Church, in which Montgomery Campbell was enthroned, was the building in which he had been ordained a priest, 38 years earlier. At first, he was doubtful about the need for a new cathedral, but once he had recognised it as a good thing
