Why is Ada Lovelace famous?
Ada Lovelace (born December 10, 1815, Piccadilly Terrace, Middlesex [now in London], England—died November 27, 1852, Marylebone, London) was an English mathematician, an associate of Charles Babbage, for whose prototype of a digital computer she created a program. She has been called the first computer programmer.
Lovelace was the daughter of famed poet Lord Byron and Annabella Milbanke Byron, who legally separated two months after her birth. Her father then left Britain forever, and his daughter never knew him personally. She was educated privately by tutors and then self-educated but was helped in her advanced studies by mathematician-logician Augustus De Morgan, the first professor of mathematics at the University of London. On July 8, 1835, she married William King, 8th Baron King, and, when he was created an earl in 1838, she became countess of Lovelace.

Lovelace became interested in Babbage’s machines as early as 1833 when she was introduced to Babbage by their mutual friend, author Mary Somerville, and, most notably, in 1843 came to translate and annotate an article written by the Italian mathematician and engineer Luigi Federico Menabrea, “Notions sur la machine analytique de Charles Babbage” (1842; “Elements of Charles Babbage’s Analytical Machine”). Her detailed and elaborate annotations (especially her description of how the proposed Analytical Engine could be programmed to compute Bernoulli numbers) were excellent; “the Analytical Engine,” she said, “weaves algebraic patterns, just as the Jacquard-loom weaves flowers and leaves.”
Babbage only built a small part of the Analytical Engine, but Lovelace’s efforts have been remembered. The early programming language Ada was named for her, and the second Tuesday in October has become Ada Lovelace Day, on which the contributions of women to science, technology, engineering, and mathematics are honoured.
