Ada Lovelace

Augusta Ada King, Countess of Lovelace (née Byron; 10 December 1815 – 27 November 1852), also known as Ada Lovelace, was an English mathematician and writer chiefly known for work on Charles Babbage's proposed mechanical general-purpose computer, the analytical engine. She was the first to recognise the machine had applications beyond pure calculation. Lovelace is often considered the first computer programmer. Lovelace was the only legitimate child of poet Lord Byron and reformer Anne Isabella Milbanke. Lord Byron separated from his wife a month after Ada was born, and died when she was eight. Although often ill in childhood, Lovelace pursued her studies assiduously. She married William King in 1835. King was a Baron, and was created Viscount Ockham and 1st Earl of Lovelace in 1838. The name Lovelace was chosen because Ada was descended from the extinct Baron Lovelaces. The title given to her husband thus made Ada the Countess of Lovelace. Lovelace's educational and social exploits brought her into contact with scientists such as Andrew Crosse, Charles Babbage, David Brewster, Charles Wheatstone and Michael Faraday, and the author Charles Dickens, contacts which she used to further her education. Lovelace described her approach as "poetical science" and herself as an "Analyst (& Metaphysician)". At age 18, Lovelace's mathematical talents led her to a long working relationship and friendship with fellow British mathematician Charles Babbage. She was particularly interested in Babbage's work on the analytical engine. Lovelace first met him on 5 June 1833, when she and her mother attended one of Charles Babbage's Saturday night soirées with their mutual friend, and Lovelace's private tutor, Mary Somerville. Though Babbage's analytical engine was never constructed and did not influence the invention of electronic computers, it has been recognised as a Turing-complete general-purpose computer, which anticipated the essential features of a modern...
