After prolonged rehabilitation, Lovelace returned to increasingly advanced private education.

The mathematician and science writer became mentor, friend and intellectual model.

At a gathering hosted by Somerville, Ada encountered Babbage and his Difference Engine.

Marriage and three children did not end her mathematical studies.
Source: www.sciencemuseum.org.ukBecomes Countess of Lovelace
Her husband’s elevation made Ada Countess of Lovelace.
Source: www.sciencemuseum.org.ukStudies advanced mathematics
Augustus De Morgan tutored Lovelace in algebra, calculus and logic through correspondence.
Source: www.sciencemuseum.org.ukBegins translating Menabrea
She translated Luigi Menabrea’s French account of Babbage’s proposed Analytical Engine.
Source: www.sciencemuseum.org.ukNotes on the Analytical Engine published
Her appended Notes expanded the article to several times its original length under the initials A.A.L.
Source: www.sciencemuseum.org.ukBernoulli-number algorithm
Note G described operations for calculating Bernoulli numbers, often called the first published computer program.
Source: www.sciencemuseum.org.ukImagines general-purpose computing
Lovelace argued that symbolic machines might compose music or manipulate other representable relationships, not merely numbers.
Source: www.sciencemuseum.org.ukAttempts mathematical betting system
A costly effort to model horse-race betting revealed the difference between formal calculation and uncertain human systems.
Source: www.sciencemuseum.org.ukDies in London
Lovelace died from uterine cancer aged thirty-six and was buried beside Lord Byron at Hucknall.
