Who Was C.S. Lewis? A Biography of the Oxford Scholar

• C.S. Lewis was an atheist before converting to Christianity in 1931, heavily influenced by J.R.R. Tolkien.
• He was a close friend of J.R.R. Tolkien and a member of the Inklings literary group.
• Lewis wrote over 30 books, spanning fiction, theology, and literary criticism.
• His most famous work, The Chronicles of Narnia, has sold over 100 million copies worldwide.
• He married Joy Davidman late in life; her death from cancer influenced his book A Grief Observed.

Lewis was born in Belfast, Ireland (now Northern Ireland), on 29 November 1898. His early life was marked by the death of his mother when he was nine years old, an event that contributed to his move to England and, later, to a period of atheism. He was educated at University College, Oxford, and served in World War I, where he was wounded in battle. After the war, he returned to Oxford and began his academic career. In 1925, he was elected a Fellow of Magdalen College, Oxford, where he taught English literature. Later, in 1954, he was appointed the Chair of Medieval and Renaissance English at Cambridge University.

His faith journey is one of the most documented aspects of his life. He abandoned the Christianity of his childhood and became an atheist as a young man. In 1929, he became a theist, admitting that God was God. Two years later, in 1931, he converted to Christianity, a decision heavily influenced by a conversation with his friend J.R.R. Tolkien. Lewis described this moment in his memoir Surprised by Joy, which traces his spiritual journey from childhood Christianity to atheism and back again.

Lewis’s literary output is vast and varied. He is often described as the author of about 40 books, or over 60 books and essays, depending on how essays, broadcasts, and other works are counted. His major works fall into several categories: fiction, Christian apologetics, and literary criticism.

This is his most famous series, consisting of seven books published between 1950 and 1956. The first book, The Lion, the Witch and the Wardrobe, introduced readers to the magical land of Narnia. The series has been adapted into multiple film series, stage productions, and audio dramas.

Mere Christianity

Originally delivered as a series of BBC radio talks during World War II, Mere Christianity was published in book form in 1952. It is a reasoned defense of Christian faith and remains one of the most influential works of Christian apologetics. Lewis used logical arguments to explain and defend core Christian beliefs.

Other Major Books

Lewis wrote several other important works. The Screwtape Letters is a satirical novel written from the perspective of a senior demon instructing a junior demon on how to tempt a human. The Problem of Pain and Miracles are theological works that explore the nature of suffering and the possibility of miracles. The Great Divorce is a fantasy novel about heaven and hell. Out of the Silent Planet, published in 1938, was his first science fiction novel. He also wrote influential literary criticism, including The Allegory of Love and English Literature in the Sixteenth Century Excluding Drama.

His conversion story is well-documented. He moved from atheism to theism in 1929, and then to Christianity in 1931. He described his conversion in his memoir Surprised by Joy. The influence of J.R.R.
