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.
Hugo Dyson
Henry Victor Dyson Dyson (7 April 1896 – 6 June 1975), generally known as Hugo Dyson and who signed his writings H. V. D. Dyson, was an English academic and a member of the Inklings literary group. He was a committed Christian, and together with J. R. R. Tolkien, he helped persuade C. S. Lewis to convert to Christianity.
