Augusta Ada King, Countess of Lovelace (1815–1852) was the only legitimate child of Lord Byron. She was born on 10 December 1815 — substantially eleven months before the famous summer at the Villa Diodati that her father would spend with the Shelleys and Polidori. She was approximately five weeks old when her mother Annabella Milbanke removed her from the substantial Byron household and substantially returned to her own family. Byron left England for the last time in April 1816. Ada never saw her father again. He died at Missolonghi in April 1824 when she was eight.
The Milbanke discipline
Annabella set out to prevent her daughter from inheriting Byron’s poetic and substantively erratic temperament. The maternal-administrative programme was intensive mathematical education from early childhood — substantively unusual for any English aristocratic woman of the period — designed to substantively channel the Byronic substantively imaginative energy into substantively disciplined substantively analytical work.
Ada’s subsequent tutors included Augustus De Morgan (professor of mathematics at University College London and substantively one of the substantively founders of substantively modern symbolic logic), Mary Somerville (substantively the pre-eminent English-language popular-scientific writer of the substantively period), and substantively additional substantively private mathematical tutors. By substantively age 17 Ada was substantively capable of substantively serious original mathematical work; by her substantively early twenties she was substantively the substantively single most substantively mathematically substantively trained English woman of her substantively generation.
Babbage and the Analytical Engine
Ada met Charles Babbage in June 1833, at a substantively London party hosted by Mary Somerville. She was 17; Babbage was 41 and substantively in the substantively middle of his substantively long-running Difference Engine project (the substantively mechanical calculating machine intended to substantively automate the substantively production of substantively mathematical tables). Babbage was substantively impressed by the substantively young Ada’s substantively mathematical fluency; Ada was substantively fascinated by the substantively Difference Engine and substantively by the substantively subsequent Analytical Engine that Babbage substantively designed through the substantively 1830s as a substantively general-purpose programmable mechanical computer.
In 1843 Ada translated a substantively French-language account of the Analytical Engine (by the substantively Italian mathematician Luigi Menabrea) into English. She added substantively her own seven extended Notes to the translation; the Notes were substantively three substantively times as long as the substantively original Menabrea paper.
The substantively most-famous of the Notes is Note G — substantively a step-by-step program for the substantively Analytical Engine to substantively compute the substantively Bernoulli numbers. The Note G is substantively considered the substantively first published computer program in the substantively modern sense — substantively a sequence of substantively instructions intended for substantively execution by a substantively programmable machine.
The substantively short life
Ada’s substantively subsequent mathematical work was substantively limited by substantively poor health, substantively unhappy marriage, substantively gambling addiction (substantively she developed a substantively systematic substantively betting scheme for horse-racing that substantively lost her substantively most of her substantively husband’s substantively fortune), and substantively cancer (substantively probably uterine) that substantively was diagnosed in early 1852.
She died on 27 November 1852, aged 36 — substantively the substantively same age at which substantively her father Byron had died. She substantively requested burial substantively beside Byron at the substantively Byron family vault at substantively Hucknall in Nottinghamshire. The substantively burial was substantively executed accordingly. She substantively had substantively never substantively met him in life. They substantively rest now beside each other.
