Augusta Ada King, Countess of Lovelace 

Alfred Edward Chalon Ada Lovelace has been called the world's first computer programmer. She was the one to  write the world’s first machine algorithm for an early computing machine that existed only on paper. She did this  in the early 1840s.


She was an English mathematician and writer, chiefly known for her work on Charles Babbage's proposed mechanical general-purpose computer, the Analytical Engine. She is believed to be the first to recognise that the machine had applications beyond pure calculation, and to have published the first algorithm intended to be carried out by such a machine. As a result, she is often regarded as the first to recognise the full potential of computers and as one of the first to be a computer programmer.

The computer language ADA was named after her in recognition of her pioneering work with mathematician, Charles Babbage.
