Ada Lovelacewas an English mathematician who wrote an algorithm for a computing machine in the mid-1800s. She has been called “the first computer programmer.”
In June 1833, Lovelace was introduced to Charles Babbage through their mutual friend Mary Somerville. Later that month, Babbage showed Lovelace his prototype for his Difference engine.
Between 1842 and 1843, Lovelace translated Luigi Menabrea’s article on Babbage’s Analytical Engine. She published her notes on the Analytical engine, which ended up being 3x longer than the article itself.
