From the New Yorker's fine piece on the Michelin guide:
The original Guide Michelin was developed by André Michelin, an engineer, and his younger brother, Édouard. Born into a wealthy manufacturing family in Clermont-Ferrand, the brothers, in 1895, presented a new design for a pneumatic tire for cars. Automobiles were still a rarity on roads in France. The brothers had the idea that a guidebook to hotels in the French countryside would encourage people to climb into a car (equipped with Michelin tires) and hit the open road. The first edition, published in 1900, was a five-hundred-and-seventy-five-page alphabetical listing of towns throughout France and the distances between them, with recommendations for hotels and places to refuel, and instructions on how to change a flat.
