Charles Babbage was thirty years old in 1821, as was his close
friend, John Herschel, and in English intellectual circles they
were both regarded as brilliant mathematicians. One day as Babbage
worked in preparing logarithmic tables, a tedious and boring task,
he commented to Herschel that he thought he could invent a machine
to do these calculations with far more speed and accuracy than a
human calculator could. And so was born an idea that would
fascinate, tantalize, and absorb him for the remainder of his life.
Over the years he drew plans, expanded them, modified them, and
finally invented two machines, the Difference Engine and the
Analytical Engine. The first was capable only of generating tables,
but the Analytical Engine could do much more. It could convert into
numbers and print the results of any formula that might be
required. It could also develop any analytical formula the laws of
whose formation were given. Using punched cards it could store
early results in a calculation and then use them to make further
calculations when they were required. He had invented the first
mechanical computer.
