C. S. Lewis
Lewis was commissioned to write the volume "English Literature in the Sixteenth Century (Excluding Drama)" for the Oxford History of English Literature, His book "A Preface to "Paradise Lost"" is still cited as a criticism of that work. His last academic work, "The Discarded Image: An Introduction to Medieval and Renaissance Literature" (1964), is a summary of the medieval world view, a reference to the "discarded image" of the cosmos.
Lewis was a prolific writer, and his circle of literary friends became an informal discussion society known as the "Inklings", including J. R. R. Tolkien, Nevill Coghill, Lord David Cecil, Charles Williams, Owen Barfield, and his brother Warren Lewis. Glyer points to December 1929 as the Inklings' beginning date. Lewis's friendship with Coghill and Tolkien grew during their time as members of the Kolbítar, an Old Norse reading group that Tolkien founded and which ended around the time of the inception of the Inklings. At Oxford, he was the tutor of poet John Betjeman, critic Kenneth Tynan, mystic Bede Griffiths, novelist Roger Lancelyn Green and Sufi scholar Martin Lings, among many other undergraduates. Curiously, the religious and conservative Betjeman detested Lewis, whereas the anti-establishment Tynan retained a lifelong admiration for him.

Lewis's interest in the works of George MacDonald was part of what turned him from atheism. This can be seen particularly well through this passage in Lewis's "The Great Divorce", chapter nine, when the semi-autobiographical main character meets MacDonald in Heaven:
He eventually returned to Christianity, having been influenced by arguments with his Oxford colleague and Christian friend J. R. R. Tolkien, whom he seems to have met for the first time on 11 May 1926, and the book "The Everlasting Man" by G. K. Chesterton. Lewis vigorously resisted conversion, noting that he was brought into Christianity like a prodigal, "kicking, struggling, resentful, and darting his eyes in every direction for a chance to escape". He described his last struggle in "Surprised by Joy":
