t on that foresight. Ada was touched by his ideas. Hardly anyone else was. Babbage worked on plans for this new engine and reported on the developments at a seminar in Turin, Italy in the autumn of 1841. An Italian, Menabrea, wrote a summary of what Babbage described and published an article in French about the development.Ada, in 1843, married to the Earl of Lovelace and the mother of three children under the age of eight, translated Menabrea's article. When she showed Babbage her translation he suggested that she add her own notes, which turned out to be three times the length of the original article. Letters between Babbage and Ada flew back and forth filled with fact and fantasy. In her article, published in 1843, Lady Lovelace's perceptive comments included her predictions that such a machine might be used to compose complex music, to produce graphics, and would be used for both practical and scientific use. She was correct.Charles Babbage, a scientist of the era was to become Ada's lifelong friend. He was a Lucasian professor of mathematics at Cambridge, was known as the inventor of the Difference Engine, an elaborate calculating machine that operated by the method of finite differences. Ada met Babbage in 1833, when she was just 17, and they began a voluminous correspondence on the topics of mathematics, logic, and ultimately all subjects.Babbage had made plans in 1834 for a new kind of calculating machine (although the Difference Engine was not finished), an Analytical Engine. His Parliamentary sponsors refused to support a second machine with the first unfinished, but Babbage found sympathy for his new project abroad. In 1842, an Italian mathematician, Louis Menebrea, published a memoir in French on the subject of the Analytical Engine. Babbage enlisted Ada as translator for the memoir, and during a nine-month period in 1842-43, she worked feverishly on the article and a set of notes she appended to it. These are the source of ...
