C. S. Lewis
Lewis and fellow novelist J. R. R. Tolkien were close friends. They both served on the English faculty at Oxford University, and were active in the informal Oxford literary group known as the Inklings. According to Lewis's memoir "Surprised by Joy", he was baptised in the Church of Ireland, but fell away from his faith during adolescence. Lewis returned to Anglicanism at the age of 32, owing to the influence of Tolkien and other friends, and he became an "ordinary layman of the Church of England". Lewis's faith profoundly affected his work, and his wartime radio broadcasts on the subject of Christianity brought him wide acclaim.
William T. Kirkpatrick
William Thompson Kirkpatrick (10 January 1848 - 22 March 1921) was an Irish teacher and grammar school headmaster. He is best known for having been the tutor of the two Lewis brothers from Belfast, Warnie Lewis and C.S. Lewis. C.S. Lewis, who would later become well known as a literary critic, novelist, and Christian apologist, lived as a resident pupil with Kirkpatrick from 1914-1917. In his autobiography, Lewis reports that he was significantly influenced by his tutor.
