C. S. Lewis, was an Irish writer and scholar. Lewis's works are diverse and include medieval literature, Christian apologetics, literary criticism, radio broadcasts, essays on Christianity, and fiction relating to the fight between good and evil. Examples of Lewis's fiction include The Screwtape Letters, The Chronicles of Narnia and The Space Trilogy.
Lewis was a close friend of J. R. R. Tolkien, the author of The Lord of the Rings. Both authors were leading figures in the English faculty at Oxford University and in the informal Oxford literary group known as the "Inklings". According to his memoir Surprised by Joy, Lewis had been baptised in the Church of Ireland at birth, but fell away from his faith during his adolescence. Owing to the influence of Tolkien and other friends, at about the age of 30, Lewis re-converted to Christianity, becoming "a very ordinary layman of the Church of England". His conversion had a profound effect on his work, and his wartime radio broadcasts on the subject of Christianity brought him wide acclaim.
On November 22, 1963, Lewis collapsed in his bedroom at 5:30 pm and died a few minutes later, exactly one week before what would have been his 65th birthday.
