Ada Lovelace was born in London, England, in 1815. She is best known for her work on a proposed mechanical general-purpose computer known as the Analytical Engine. She created the first algorithm and is often credited as the first computer programmer. Lovelace was the only legitimate daughter of the poet Lord Byron and his wife Anne. (His other children were born out of wedlock with other women.) Byron left Anne only a month after Ada was born and died when Ada was 8 years old. Anne remained bitter toward her husband and encouraged Ada’s love of mathematics and logic in an effort to subvert the madness that had seemed to grip Byron. Never close with her mother, she was raised by her grandmother and led a fairly scandalous adult life, with numerous purported affairs and a love of gambling. One project that never reached fruition was her desire to create a mathematical model for how the brain gives rise to thoughts and nerves to feelings, a ‘calculus of the nervous system’. Her interest in the brain came from an obsessive focus on the potential madness she may have inherited from her father. Ada died at the age of 36, most likely from uterine cancer.
