Augusta Ada King, Countess of Lovelace (
née Byron; 10 December 1815 – 27 November 1852) 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 recognised as the first
algorithm intended to be carried out by a machine. As a result, she is often regarded as the first computer
programmer.
Ada Lovelace was the only legitimate child of the poet George Lord Byron and his wife
Anne Isabella Milbanke ("Annabella"), Lady Wentworth.
All
Byron's other children were born out of wedlock to other women.
Byron separated from his wife a month after Ada was born and left
England forever four months later, eventually dying of disease in the
Greek War of Independence
when Ada was eight years old. Her mother remained bitter towards Lord
Byron and promoted Ada's interest in mathematics and logic in an effort
to prevent her from developing what she saw as the
insanity
seen in her father, but Ada remained interested in him despite this
(and was, upon her eventual death, buried next to him at her request).
Often ill, she spent most of her childhood sick. Ada married
William Lord King in 1835. King was made Earl of Lovelace in 1838, and she became Lady Lovelace.
Her educational and social exploits brought her into contact with scientists such as
Andrew Crosse,
Sir David Brewster,
Charles Wheatstone,
Michael Faraday and the author
Charles Dickens, in which she used to further her education. Ada described her approach as "poetical science" and herself as an "Analyst (& Metaphysician)".
As a teenager, her mathematical talents led her to an ongoing working
relationship and friendship with fellow British mathematician Charles
Babbage, also known as 'the father of computers', and in particular,
Babbage's work on the Analytical Engine. Lovelace first met him in June
1833, through their mutual friend, and her private tutor,
Mary Somerville. Between 1842 and 1843, Ada translated an article by Italian military engineer
Luigi Menabrea on the engine, which she supplemented with an elaborate set of notes, simply called
Notes.
These notes contain what many consider to be the first computer
program—that is, an algorithm designed to be carried out by a machine.
Lovelace's notes are important in the early
history of computers.
She also developed a vision of the capability of computers to go beyond
mere calculating or number-crunching, while many others, including
Babbage himself, focused only on those capabilities.
Her mind-set of "poetical science" led her to ask questions about the
Analytical Engine (as shown in her notes) examining how individuals and
society relate to technology as a collaborative tool.
She died of uterine cancer in 1852 at the age of 36.
