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
Both Tolkien's academic career and his literary production are inseparable from his love of language and philology. He specialized in English philology at university and in 1915 graduated with Old Norse as his special subject. He worked for the Oxford English Dictionary from 1918 and is credited with having worked on a number of words starting with the letter W, including walrus, over which he struggled mightily. In 1920, he became Reader in English Language at the University of Leeds, where he claimed credit for raising the number of students of linguistics from five to twenty. He gave courses in Old English heroic verse, history of English, various Old English and Middle English texts, Old and Middle English philology, introductory Germanic philology, Gothic, Old Icelandic, and Medieval Welsh. When in 1925, aged thirty-three, Tolkien applied for the Rawlinson and Bosworth Professorship of Anglo-Saxon at Pembroke College, Oxford, he boasted that his students of Germanic philology in Leeds had even formed a "Viking Club". He also had a certain, if imperfect, knowledge of Finnish.
