A city guy who aspired to be a farmer, John Byron Plato took a three-month winter course in agriculture at Cornell before starting high school, which he left a year before graduation to fight in the Spanish-American War. He worked as a draftsman, ran a veneers business, patented and manufactured a parking brake for horse-drawn delivery wagons, taught school, and ran a lumber yard. In his early thirties he bought some farmland north of Denver, Colorado, and began raising Guernsey cattle, which he advertised for sale in the local paper. When an interested buyer eager to see his calves couldn’t find his farm, Plato realized that an RFD postal address was only good for delivering mail. Plato’s solution was a map-and-directory combo that used direction and distance from a local business center to give farmers a real address, just like city dwellers. He patented his invention called the “Clock System” and tried to sell it to the Post Office Department. What follows is a tale of persistence and failure as rural farming declined and technology and capitalism overtook John Byron Plato’s chances at geographic immortality.

This book explores the US patent system, which helped practical minded innovators establish intellectual property rights and fulfill the need for achievement that motivates inventors and scholars alike. In this sense, the patent system was a parallel literature: a vetting institution similar to the conventional academic-scientific-technical journal insofar as the patent examiner was both editor and peer reviewer, while the patent attorney was a co-author or ghost writer. In probing evolving notions of novelty, non-obviousness, and cumulative innovation, Mark Monmonier examines rural address guides, folding schemes, world map projections, diverse improvements of the terrestrial globe, mechanical route-following machines that anticipated the GPS navigator, and the early electrical you-are-here mall map, which opened the way for digital cartography and provided fodder for patent trolls, who treat the patent largely as a license to litigate.
