Oxford Dictionary of National Biography podcast: Ada Lovelace, mathematician and computer pioneer, 1815-1852
“Ada’s work was published in September 1843 in Taylor’s Scientific Memoirs (vol. 3) as ‘Sketch of the analytical engine invented by Charles Babbage esq. by L. F. Menabrea, of Turin, officier of the military engineers’. The translator and annotator is not identified on the title page, but each of her notes is individually signed AAL (Augusta Ada Lovelace). She asked penetrating questions about how the analytical engine might be applied, and hypothesized that if it could understand the relations of pitched sounds and the science of harmony ‘the engine might compose elaborate and scientific pieces of music of any degree of complexity and extent’ (Scientific Memoirs, 3, 1843, 694). She also saw the graphical potential of the analytical engine, and that by changing to a new medium, the punched card, scientific information would be seen in a new light. Thus, in a famous and influential metaphor, she wrote ‘Analytical Engine weaves algebraical patterns just as the Jacquard loom weaves flowers and leaves’.”
