Babbage was a mechanical genius. In the 1820s, at the onset of the industrial revolution, he designed (and built a working model of) a difference engine, a device that could automatically generate tables of logarithms and other mathematical functions. Then, in the 1830s, he designed and partially built his analytical engine, a forerunner of the modern computer that used gears and rods to perform its computations. Unfortunately, Babbage was too far ahead of his time; due in part to the limitations of early nineteenth-century technology, he never finished building either of these machines.
