Ada All-Time

Short answer: Ada Lovelace (1815-1852) was an English mathematician who worked with Charles Babbage on his proposed Analytical Engine, a mechanical general-purpose computer. In 1843 she translated an article by Luigi Menabrea about the engine from French and added her own notes, which were longer than the article.

Note G sets out an algorithm for computing Bernoulli numbers on the engine, often called the first published computer program. She also suggested the machine could act on things other than numbers, such as music. Historians debate how much credit belongs to her versus Babbage. The engine was never built. The footage shows portraits of Lovelace and Babbage, with the presenter.

Video transcript: Ada All-Time: A Program Was Written for a Computer That Was Never Built

Ada Lovelace often regarded as the world's first computer programmer had an influential partnership with Charles Babbage the inventor of the Analytical Engine a design considered as an early prototype for a general-purpose computer. DID YOU KNOW? While translating an article about Babbage's Analytical Engine from French to English Lovelace added extensive notes and annotations. In her notes she included an algorithm intended for the Analytical Engine to calculate Bernoulli numbers making her the first person to recognize that a machine could manipulate symbols beyond mathematical calculations. Ada Lovelace's foresight went beyond Babbage's ideas laying the groundwork for the concept of computer programming NOW YOU KNOW!
