Ronald Arbuthnott Knox (17 February 1888 – 24 August 1957) was an English Catholic priest, theologian, author, and radio broadcaster.

Educated at Eton and Balliol College, Oxford, where he earned a high reputation as a classicist, Knox was ordained as a priest of the Church of England in 1912.

Ronald's maternal grandfather was Valpy French, the first Anglican Bishop of Lahore in what was then part of the British Raj.

[7] As he was not expected to begin tutorials until 1911, Knox then accepted the job of private tutor to Harold Macmillan, the brother of a friend from Eton, who was at the time preparing to apply for a scholarship to Balliol.

Knox was long remembered at Shrewsbury as the highly dedicated and entertaining form master of Vb.

[11] In 1918, Knox was ordained a Catholic priest and in 1919 joined the staff of St Edmund's College in Ware, Hertfordshire, remaining there until 1926.

Knox stated that his conversion was influenced in part by G. K. Chesterton,[12] who was a High Church Anglican at the time, but not yet a Catholic.

[15] In 1936, directed by his religious superiors, Knox started retranslating the Latin Vulgate Bible into English using Hebrew and Greek sources.

His works on religious themes include: Some Loose Stones (1913), Reunion All Round (1914), A Spiritual Aeneid (1918), The Belief of Catholics (1927), Caliban in Grub Street (1930), Heaven and Charing Cross (1935), Let Dons Delight (1939) and Captive Flames (1940).

At the invitation of Harold Macmillan, Knox stayed at 10 Downing Street while consulting a medical specialist in London.

Bishop George L. Craven celebrated the requiem Mass and Fr Martin D'Arcy preached the panegyric.

[20] In January 1926, on BBC Radio, Knox presented Broadcasting the Barricades, a simulated live report of revolution in London.

The lack of newspapers caused a minor panic, as people believed that the broadcast events in London were to blame.
