Augusta Ada King, Countess of Lovelace (10 December 1815 – 27 November 1852), born Augusta Ada Byron and now commonly known asAda Lovelace, was an English mathematician and writer chiefly known for her work on Charles Babbage‘s early mechanical general-purpose computer, the Analytical Engine. Her notes on the engine include what is recognized as the first algorithm intended to be processed by a machine. Because of this, she is often considered the world’s first computer programmer.
She was born 10 December 1815 as the only legitimate child to the poet Lord Byron and his wife Anne Isabella Byron – all of his other children were born out of wedlock. Byron separated from his wife a month after Ada was born and left England forever four months later, eventually dying of disease in theGreek War of Independence when Ada was only eight years old. Ada’s mother remained bitter at Lord Byron and promoted Ada’s interest inmathematics and logic in an effort to prevent her from developing what she saw as insanity in her father, but she remained interested in him despite this (and was, upon her eventual death, buried next to him at her request).
