9. The assembly line, 1913

Turned a craft-based economy into a mass-market one. The most significant piece of Ford’s efficiency crusade was the assembly line. Inspired by the continuous-flow production methods used by flour mills, breweries, canneries and industrial bakeries, along with the disassembly of animal carcasses in Chicago’s meat-packing plants, Ford installed moving lines for bits and pieces of the manufacturing process: For instance, workers built motors and transmissions on rope-and-pulley–powered conveyor belts.
