Augusta Aa Byron King, Countess of Lovelace (December 10, 1815 London, England – November 27, 1852 Marylebone, London, England), born Augusta Ada Byron, is mainly known for having written a description of Charles Babbage's early mechanical general-purpose computer, the analytical engine. She is today appreciated as the "first programmer" since she was writing programs—that is, manipulating symbols according to rules—for a machine that Babbage had not yet built. She also foresaw the capability of computers to go beyond mere calculating or number-crunching while others, including Babbage himself, focused only on these capabilities.
