English mathematician and writer chiefly known for her work on Charles Babbage's proposed mechanical general-purpose computer, the Analytical Engine. In 1843 she published an extensive set of notes on the machine, translated and annotated from an Italian memoir, in which Note G describes a method for the engine to compute Bernoulli numbers: an algorithm now recognized as the first published, machine-executable program, written before any such machine had been built. She also anticipated that a machine acting on symbols rather than mere numbers could compose music or manipulate any content expressible in formal rules, a leap beyond Babbage's own conception of the Engine as a calculator.
Facts
Death PlaceMarylebone, London, England 1 Nationality / Culture Defining ContributionWrote, in her 1843 Notes on the Analytical Engine, an algorithm for computing Bernoulli numbers on Babbage's proposed machine, generally recognized as the first algorithm published for execution by a machine; also articulated, ahead of Babbage himself, that a symbol-manipulating engine could act on more than numbers. 1 Notable WorkNotes on the Analytical Engine (1843), especially Note G, containing the Bernoulli-number algorithm 1 Cross-Tradition Connections
Associated With
Author of the first algorithm published for execution by a machine (Note G, 1843).
In Branch
Her work is computational rather than in a classical pure-mathematics branch: an algorithm for a proposed calculating machine.
