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.
A Voyage to Arcturus
The novel was a central influence on C. S. Lewis's 1938–1945 "Space Trilogy". Lewis also mentioned the "sorbing" (aggressive absorption of another's personality into one's own, fatal to the other person) as an influence on his 1942 book "The Screwtape Letters". Lewis in turn recommended the book to J. R. R. Tolkien, who said he read it "with avidity".
