C. S. Lewis
Lewis and fellow novelist J. R. R. Tolkien were close friends. They both served on the English faculty at Oxford University, and were active in the informal Oxford literary group known as the Inklings. According to Lewis's memoir "Surprised by Joy", he was baptised in the Church of Ireland, but fell away from his faith during adolescence. Lewis returned to Anglicanism at the age of 32, owing to the influence of Tolkien and other friends, and he became an "ordinary layman of the Church of England". Lewis's faith profoundly affected his work, and his wartime radio broadcasts on the subject of Christianity brought him wide acclaim.
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.
