George MacDonald 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,Walter de la Mare,E. Nesbit 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".
Vannevar Bush was an American engineer, inventor and science administrator, who during World War II headed the U.S. Office of Scientific Research and Development , through which almost all wartime military R&D was carried out, including initiation and early administration of the Manhattan Project. He is also known in engineering for his work on analog computers, for founding Raytheon, and for the memex, a hypothetical adjustable microfilm viewer with a structure analogous to that of hypertext. In 1945, Bush published the essay "As We May Think" in which he predicted that "wholly new forms of encyclopedias will appear, ready made with a mesh of associative trails running through them, ready to be dropped into the memex and there amplified". The memex influenced generations of computer scientists, who drew inspiration from its vision of the future. He was chiefly responsible for the movement that led to the creation of the National Science Foundation.
