Britannica records Ada Lovelace (1815–1852) as an English mathematician, Charles Babbage collaborator, and author of an 1843 Analytical Engine program, and states that she died at thirty-six from uterine cancer. The Computer History Museum confirms Lovelace’s 1843 annotated translation of Menabrea’s paper and describes her notes as containing the first published stepwise sequence of operations for solving mathematical problems. The Science Museum Group Collection corroborates her years, work on Babbage’s Analytical Engine, Bernoulli-number algorithm, symbolic vision beyond calculation, and death from cancer at age thirty-six. Her worth lies in seeing general-purpose symbolic computation before working computers existed.
