Martin was 95 years old when he died, and had written 70 or 80 books during his long lifetime as an author. Martin's first Dover books were published in 1956 and 1957: \u003ci\u003eMathematics, Magic and Mystery,\u003c\/i\u003e one of the first popular books on the intellectual excitement of mathematics to reach a wide audience, and \u003ci\u003eFads and Fallacies in the Name of Science,\u003c\/i\u003e certainly one of the first popular books to cast a devastatingly skeptical eye on the claims of pseudoscience and the many guises in which the modern world has given rise to it. Both of these pioneering books are still in print with Dover today along with more than a dozen other titles of Martin's books. They run the gamut from his elementary \u003ci\u003eCodes, Ciphers and Secret Writing,\u003c\/i\u003e which has been enjoyed by generations of younger readers since the 1980s, to the more demanding \u003ci\u003eThe New Ambidextrous Universe: Symmetry and Asymmetry from Mirror Reflections to Superstrings,\u003c\/i\u003e which Dover published in its final revised form in 2005.  \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eTo those of us who have been associated with Dover for a long time, however, Martin was more than an author, albeit a remarkably popular and successful one. As a member of the small group of long-time advisors and consultants, which included NYU's Morris Kline in mathematics, Harvard's I. Bernard Cohen in the history of science, and MIT's J. P. Den Hartog in engineering, Martin's advice and editorial suggestions in the formative 1950s helped to define the Dover publishing program and give it the point of view which — despite many changes, new directions, and the consequences of evolution — continues to be operative today.  \u003c\/p\u003e\n\u003cp\u003e\u003cb\u003e \u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eIn the Author's Own Words:\u003cbr\u003e\"Politicians, real-estate agents, used-car salesmen, and advertising copy-writers are expected to stretch facts in self-serving directions, but scientists who falsify their results are regarded by their peers as committing an inexcusable crime.
