A unique take on the unrealized invention of the computer in the 1830s by the eccentric polymath Charles Babbage and his accomplice, the daughter of Lord Byron, Ada, Countess of Lovelace. When Ada translated her friend Babbage's plans for the "Difference Engine," her lengthy footnotes contained the first appearance of the general computing theory—one hundred years before an actual computer was built. Sadly, Lovelace died of cancer a few years after publishing the paper, and Babbage never built any of his machines.
