“France had recently switched to the metric system of measurement. This gave scientists a much-needed standardized system to measure and compare results, but it also required a whole new set of calculating tables. The sheer number of calculations was beyond what could be accomplished by all the mathematicians in France, so Riche established calculating 'factories' to manufacture logarithms the same way workers manufactured mercantile goods. Each factory employed between 60 and 80 human 'computers.' But they weren’t trained mathematicians; they were mostly out-of-work hairdressers who had found their skill at constructing elaborate pompadours for aristocrats much less in demand after so many former clients lost their heads at the height of the French Revolution. Riche had hit upon a rote system of compiling results based on a set of given values and formulas, and the workers just cranked out the answers in what must have been the world’s first mathematical assembly line. Babbage figured that if an army of untrained hairdressers could make the calculations, so could a computing 'engine.”
