John Henry Newman (21 February 1801 – 11 August 1890) was an English Catholic theologian, academic, philosopher, historian, writer, and poet. He was previously an Anglican priest and after his conversion became a cardinal. He was an important and controversial figure in the religious history of England in the 19th century and was known nationally by the mid-1830s. He was canonised as a Catholic saint in 2019. He was a member of the Oratory of St. Philip Neri.

Originally an evangelical academic at the University of Oxford and priest in the Church of England, Newman was drawn to the high church tradition of Anglicanism. He became one of the more notable leaders of the Oxford Movement, an influential and controversial grouping of Anglicans who wished to restore to the Church of England many Catholic beliefs and liturgical rituals from before the English Reformation. In this, the movement had some success. After publishing his controversial Tract 90 in 1841, Newman later wrote: “I was on my death-bed, as regards my membership with the Anglican Church.”
