Ada Lovelace
Augusta Ada King, Countess of Lovelace (1815–1852), was an English mathematician and writer chiefly known for her work on Charles Babbage's proposed mechanical general-purpose computer, the analytical engine. She was the first to recognise the machine had applications beyond pure calculation and is often considered the first computer programmer. The only legitimate child of poet Lord Byron and reformer Anne Isabella Milbanke, Lovelace pursued mathematics from an early age despite frequent illness.

Publishes Notes
Publishes translation of Menabrea's paper with extensive notes on the Analytical Engine
Death
Dies of cervical cancer at age 36 on 27 November
Lovelace described her approach as "poetical science" and herself as an "Analyst (& Metaphysician)". She believed that intuition and imagination were critical to effectively applying mathematical and scientific concepts, viewing both metaphysics and mathematics as tools for exploring "the unseen worlds around us".
The Analytical Engine Notes
Translated Menabrea's paper on Babbage's Analytical Engine and added seven extensive notes, including the first published computer algorithm for calculating Bernoulli numbers.
Note G - First Computer Program
Described in complete detail a method for calculating Bernoulli numbers using the Analytical Engine, often called the first published computer program.
Vision of Computing Potential
Recognized that the Analytical Engine could manipulate symbols according to rules, not just numbers, anticipating modern computing applications including music composition.
Mathematical Research
Studied advanced calculus including Bernoulli numbers under Augustus De Morgan, who suggested she might become "an original mathematical investigator of first-rate eminence".
**Legacy and Commemoration**
Ada Lovelace's contributions to computing are widely commemorated today. The programming language Ada was named after her, with its reference manual approved on her birthday (10 December 1980). Ada Lovelace Day, celebrated annually on the second Tuesday of October, aims to raise the profile of women in science, technology, engineering, and mathematics.
Numerous institutions, awards, and buildings bear her name, including the Lovelace Medal from the British Computer Society, Ada Developers Academy, and the Ada Lovelace Institute. Her vision of computing's potential beyond mere calculation anticipated the digital age by more than a century.
