It was not until the appearance of his second allegorical work, The Allegory of Love (1936), however, that Lewis was honored with the coveted Hawthornden prize.

The Screwtape Letters (1942), for which Lewis is perhaps best known, is a satire in which the devil, here known as Screwtape, writes letters teaching his young nephew, Wormwood, how to tempt humans to sin. Lewis published seven religious allegories for children titled Chronicles of Narnia (1955). He also published several scholarly works on literature, including English Literature in the 16th Century (1954) and Experiment in Criticism (1961).

Although Lewis went on to publish several works involving religion, he had lost interest in it early in life and only later "converted" to Christianity, joining the Anglican Church. His autobiography (the story of his own life), Surprised by Joy: The Shape of My Early Life, fails to explain what happened in his childhood. His headmaster in boarding school, a minister who urged him to "think" by hitting him, may have contributed to this change.

Later years

Lewis went on to become a professor of English at Cambridge University, England, in 1954. Widely read as an adult, his knowledge of literature made him much sought after for his company and conversation. Lewis thoroughly enjoyed sitting up into the late hours in college rooms talking about literature, poetry, and religion.

In 1956, rather late in life, Lewis married Joy Davidman Gresham, the daughter of a New York Jewish couple. She was a graduate of Hunter College and had previously been married twice. When her first husband suffered a heart attack, she turned to prayer. Reading the writings of Lewis, she began attending church. Later, led by his writings to Lewis himself, she divorced her second husband, Williams Gresham, and married Lewis. She died some three years before her husband. C. S. Lewis died at his home in Headington, Oxford, England, on November 24, 1963. A major collection of his works is held by Wheaton College in Illinois.
