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 modern fantasy literature and the mentor of fellow writer Lewis Carroll. In addition to his fairy tales, MacDonald wrote several works on Christian apologetics.
His writings have been cited as a major literary influence by many notable authors including Lewis Carroll, W. H. Auden, J. M. Barrie, Lord Dunsany, Elizabeth Yates, Oswald Chambers, Mark Twain, Hope Mirrlees, Robert E. Howard, L. Frank Baum, T.H. White, Richard Adams, Lloyd Alexander, Hilaire Belloc, G.K. Chesterton, C. S. Lewis, J. R. R. Tolkien, Walter de la Mare, E. Nesbit, Peter S. Beagle, Neil Gaiman and Madeleine L'Engle.
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".
