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.
J. R. R. Tolkien
The Tolkiens had four children: John Francis Reuel Tolkien (17 November 1917 – 22 January 2003), Michael Hilary Reuel Tolkien (22 October 1920 – 27 February 1984), Christopher John Reuel Tolkien (born 21 November 1924) and Priscilla Mary Anne Reuel Tolkien (born 18 June 1929). Tolkien was very devoted to his children and sent them illustrated letters from Father Christmas when they were young. Each year more characters were added, such as the North Polar Bear (Father Christmas's helper), the Snow Man (his gardener), Ilbereth the elf (his secretary), and various other, minor characters. The major characters would relate tales of Father Christmas's battles against goblins who rode on bats and the various pranks committed by the North Polar Bear.
