George MacDonald (10 December 1824 – 18 September 1905) was a Scottish author, poet, and Christian minister. He was a pioneering figure in the field of fantasy literature and the mentor of fellow writer Lewis Carroll. His writings have been cited as a major literary influence by many notable authors including W. H. Auden, C. S. Lewis, J. R. R. Tolkien, E. Nesbit and Madeleine L'Engle.[1] C. S. Lewis wrote that he regarded MacDonald as his "master": "Picking up a copy of Phantastes one day at a train-station bookstall, I began to read. A few hours later," said Lewis, "I knew that I had crossed a great frontier." G. K. Chesterton cited The Princess and the Goblin as a book that had "made a difference to my whole existence".
