"George Boole took up Leibniz's idea, and wrote a book he called . The laws he formulated are now called ... William Stanley Jevons heard of Boole's work, and undertook to build a machine to make calculations in Boolean algebra. He successfully designed and built such a machine, which he called the Logical Piano, apparently because it was about the size and shape of a small piano. This machine and its creator deserve much more fanfare than they have so far received. This was the first machine to do mechanical inference.
