James Henry Davies Clarke • 2026-07-01 • Reviewed by Daniel Mercer

Clive Staples Lewis, known to millions as C. S. Lewis, was a towering figure of 20th-century literature whose work continues to shape the worlds of fantasy and Christian thought. Born in Belfast in 1898, he lived a life marked by a profound intellectual journey from atheism to faith, producing beloved classics such as The Chronicles of Narnia and Mere Christianity.

As a professor at both Oxford and Cambridge, Lewis used his sharp intellect to defend Christian faith in a modern age, while also creating imaginative worlds that captivated children and adults alike. His legacy as an author, scholar, and apologist remains influential decades after his death.

This article explores his life story, major works, religious conversion, and the circumstances surrounding his death, offering a detailed look at the man behind the stories.

Who Was C. S. Lewis? A Brief Biography

Early Life and Education (Young C.S. Lewis)

Born on 29 November 1898 in Belfast, Ireland (now Northern Ireland), Lewis was raised in a bookish Protestant family. His father, Albert Lewis, was a solicitor, and his mother, Florence Augusta Hamilton, was the daughter of a clergyman. The loss of his mother to cancer when he was just nine years old was a formative trauma, one he later cited as the basis for his early pessimism and atheism. He abandoned his childhood Christianity around 1911 and 1912, becoming an avowed atheist, an influence he attributed to his boarding school matron and a friend named Kirkpatrick.

Academic Career at Oxford and Cambridge

Lewis entered Oxford in 1917 to study Classics at University College but soon volunteered for active service in World War I. On 15 April 1918, he was wounded by a British shell in the village of Riez du Vinage; two colleagues were killed in the same burst. After the war, he returned to Oxford, achieving a “double first” in Honours Moderations and Greats, then taking an additional first in English language and literature.

In 1925, he became a fellow and tutor of Magdalen College, Oxford, a position he held until 1954. This period saw the formation of the Inklings, the literary discussion group that included C.S. Lewis‘s close friend, J.R.R. Tolkien. In 1954, he was appointed Professor of Medieval and Renaissance English at the University of Cambridge, a chair he held until his death in 1963, though he always kept his home and his heart in Oxford.

Marriage to Joy Davidman and Family Life

Lewis married the American writer Joy Davidman in 1956. The marriage was initially a civil ceremony to allow her to remain in England, but it deepened into a profound love story, marked by Joy’s battle with cancer. Their relationship was dramatized in the film and stage production Shadowlands. Lewis did not have biological children, but after Joy’s death in 1960, he raised her two sons, David and Douglas Gresham.

Religious Conversion and Faith Journey

Lewis’s return to faith was gradual. He acknowledged that “God was God” in the Trinity Term of 1929, becoming a theist. He then converted to Christianity in 1931, a journey significantly aided by his devoutly Catholic friend J.R.R. Tolkien and another friend, Hugo Dyson. Lewis became an Anglican lay theologian and a popular lecturer and broadcaster, using reason to argue for the existence of God.

Key Insight: From Atheist to Apologist

C.S. Lewis is one of the most influential Christian apologists of the 20th century, yet he was an atheist as a young man. His friendship with J.R.R. Tolkien was pivotal in his conversion to Christianity.

Key Insights into His Life

  • He was an atheist as a young man before converting to Christianity.
  • His friendship with J.R.R. Tolkien was central to his faith journey.
  • He served in World War I and was wounded in battle.
  • He never had biological children but raised two stepsons.
  • He died on the same day as President John F. Kennedy and author Aldous Huxley.

What Are the Most Famous Books by C. S. Lewis?

The Chronicles of Narnia Series

The Chronicles of Narnia is a series of seven fantasy novels published between 1949 and 1954. It is considered a classic of children’s literature, having sold over 100 million copies in 47 languages. The series includes The Lion, the Witch and the Wardrobe (1950), which remains its most famous entry. Lewis crafted Narnia as a place of adventure and moral inquiry, weaving in Christian themes without making it a strict allegory.

Mere Christianity and Christian Apologetics

Mere Christianity (1952) is arguably his most influential theological work. It originated as a series of BBC radio talks broadcast during World War II. In it, Lewis refutes popular objections to Christianity, including the problem of pain. He also presented his famous “Trilemma” argument—that Jesus was either Lord, Liar, or Lunatic—as a rational basis for faith.

Other key apologetic works include The Problem of Pain (1940), The Screwtape Letters (a satirical series of letters from a senior demon to a junior tempter), and The Great Divorce.

The Space Trilogy and Other Fiction

Lewis also wrote science fiction, including the Space Trilogy (Out of the Silent Planet, Perelandra, That Hideous Strength), which explores themes of fall, redemption, and the nature of humanity. His allegorical work The Pilgrim’s Regress (1933) was his first book after his conversion, chronicling his spiritual journey.

Context: What is ‘Mere Christianity’ About?

The book attempts to outline the core, shared beliefs of the Christian faith—what Lewis called “mere Christianity.” It was not written to promote a specific denomination but to explain and defend the Christian worldview to a skeptical modern audience. It remains a staple of modern evangelical thought and is widely read by seekers and believers alike.

Famous C. S. Lewis Quotes

“To love at all is to be vulnerable.”

— The Four Loves

“I believe in Christianity as I believe that the sun has risen: not only because I see it, but because by it I see everything else.”

— Essay ‘Is Theology Poetry?’

“You can never get a cup of tea large enough or a book long enough to suit me.”

How Did C. S. Lewis Die? Cause of Death and Final Years

Timeline of Final Illness and Death

In the years leading up to his death, Lewis suffered from a number of health issues, including a heart condition. In June 1963, a severe illness forced him to retire early from his position at Cambridge. He never fully recovered. On 22 November 1963, he died at his home in Oxford, Oxfordshire, England, after suffering a sudden heart attack (heart failure). He was just days shy of his 65th birthday.

The date of his death is historically notable because it coincides with the assassination of U.S. President John F. Kennedy and the death of the author Aldous Huxley. Lewis was buried in the churchyard of Holy Trinity Church, Headington, Oxford.

Clarification: Cause of Death

While some sources cite heart failure (a sudden heart attack), others mention renal failure (kidney failure). The most reliable biographical accounts specify a sudden heart attack as the immediate cause of death. Lewis had been in declining health for months prior.

Established Information Information That Remains Unclear / Is a Myth
Lewis was an Anglican lay theologian. Myth: Lewis was a Catholic. Truth: He was firmly Anglican and had some theological disagreements with Roman Catholicism, despite his friendship with the Catholic Tolkien.

The Lasting Impact of C. S. Lewis

C. S. Lewis’s legacy is defined by his ability to blend rigorous intellectual argument with imaginative storytelling. His “Trilemma” argument (Lord, Liar, or Lunatic) remains a staple of Christian apologetics, while The Chronicles of Narnia continues to introduce new readers to spiritual themes through fantasy.

His style differs markedly from that of his friend Tolkien’s epic high fantasy. Where Tolkien built a vast mythology with complex invented languages, Lewis wrote a more direct, fairy-tale style of portal fantasy. This accessibility is a key reason Narnia remains popular decades after its publication, while also being a source of deeper theological reflection.

He is arguably the most influential religious writer of his day, a legacy cemented by his presence in the Poets’ Corner in Westminster Abbey, where he was memorialized in 2013.
