George MacDonald (1824-1905), was a Scottish author, poet, and Christian minister. Though no longer well known, his works (particularly his fairy tales and fantasy novels) have inspired admiration in such notables as W. H. Auden, J. R. R. Tolkien, and Madeleine L'Engle. C. S. Lewis wrote that he regarded MacDonald as his "master." Even Mark Twain, who initially detested MacDonald, became friends with him, and there is some evidence that Twain was influenced by MacDonald.
