“the U.S. Department of State and the chief cartographer for the American Geographical Society, and with two mathematicians who later became the authors of Mr. Mits. All three experts stated that my presentation was ‘pure invention,’ using the term in a derogatory manner. They did so because it did not conform to any of the known methods of projection. My method of projection is based on a three-way grid of great circles which, as the patent shows, does occur with a 60-degree-edge-angle vector equilibrium. The mathematicians said a three-way grid of great circles was unknown, and in fact was impossible. I was able to make graphic demonstration of my three-way grid, finely etched on a 12-inch-diameter copper hemisphere using the great circle edge of a fine tolerance enclosing hemisphere as the great circle scribe guide. The three-way great circle grid sprang from a uniform boundary scale of one-degree increments. Because of my demonstration Life Magazine went ahead with the publishing. My patent attorney then informed me that the patent examiner had ruled circa 1900 that no new cartographic projections could be patented because all the mathematical variations had been ramified. My patent attorney confronted the patent examiner with the three authority’s statements that what”
