<strong>Babbage</strong> was only a few years out <strong>of</strong> Cambridge when<br />

he decided to devote his efforts to the production <strong>of</strong> a<br />

Difference Engine. He announced this by writing an open<br />

letter to Sir Humphry Davy, the president <strong>of</strong> the Royal<br />

Society. In it he describes the concept, his pilot project,<br />

his critical results and eventually, in the last sentence, an<br />

indirect request for financial support:<br />

It must however be attained at a very considerable<br />

expense, which would not probably be replaced,<br />

<strong>Babbage</strong>, <strong>Charles</strong><br />

by the works it might produce, for a long period<br />

<strong>of</strong> time, and which is an undertaking I should feel<br />

unwilling to commence, as altogether foreign to<br />

my habits and pursuits.<br />

The letter was widely circulated and eventually resulted<br />

in the government granting funds for the construction <strong>of</strong><br />

<strong>Babbage</strong>’s Difference Engine. Significantly, the letter<br />

also contains remarks showing that <strong>Babbage</strong> had been<br />

thinking <strong>of</strong> other forms <strong>of</strong> calculating machines.<br />
