A man of many talents, the Earl designed a guile called the Stanhope Demonstrator, which was a small shock with a window in the top, along with two disparate colored slides that the user pushed into slots in the sides.

In position it wasnt until almost sixty years after his death that the Earls notes and one of his devices ferocious into the hands of the Reverend Robert Harley, who later on published an word on the Stanhope Demonstrator in 1879. Working on a somewhat different a pproach was the British logician and economic expert William Stanley Jevons, who, in 1869, produced the earliest model of his famous Jevons logical system Machine. The Jevons Logic Machine was notable because it was the first machine that could solve a logical problem faster than that problem could be solved without using the machine!

Jevons was an aficionado of Boolean logic, and his solution was something of a get well between a logical abacus and a cushy (in fact it was sometimes referred to as a Logic pianissimo). This device, which was about 3 feet tall, consisted of keys, levers, and pulleys, along with gar ner that could be all conspicuous or hidde! n. When the operator pressed keys representing logical operations, the discriminate letters appeared to reveal the result.
