C. S. Lewis

Clive Staples Lewis (29 November 1898 – 22 November 1963), commonly referred to as C. S. Lewis and known to his friends and family as "Jack", was an Irish-born British novelist, academic, medievalist, literary critic, essayist, lay theologian and Christian apologist. He is well known for his fictional work, especially The Screwtape Letters, The Chronicles of Narnia and The Space Trilogy.

Lewis was a close friend of J. R. R. Tolkien, and 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 the age of 32 Lewis returned to Christianity, becoming "a very ordinary layman of the Church of England".[2] His conversion had a profound effect on his work, and his wartime radio broadcasts on the subject of Christianity brought him wide acclaim.
