C. S. Lewis
After his conversion to theism in 1929, Lewis converted to Christianity in 1931, following a long discussion and late-night walk with his close friends Tolkien and Hugo Dyson. He records making a specific commitment to Christian belief while on his way to the zoo with his brother. He became a member of the Church of England – somewhat to the disappointment of Tolkien, who had hoped that he would join the Catholic Church.
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.
