Augusta Ada King, the Countess of Lovelace, is known as a computer pioneer due to her contributions to the Analytical Engine from Charles Babbage.
Her translation of Luigi Federico Menabrea’s paper on the Analytical Engine triplicated the extend of the original text, enriched by Augusta Ada King’s notes. She included a stepwise sequence of operations, and she referred to the ‘science of operation’, which may be understands as ‘computing’.
While her contribution is still debated, and the undervalue of her achievements may be presented as an example of the Matilda Effect, there is agreement on describing Ada as a visionary.
