What did lady Augusta Ada invent?

Lady Augusta Ada Lovelace is often credited with being one of the first computer programmers due to her work on Charles Babbage's early mechanical general-purpose computer, the Analytical Engine. She wrote what is considered the first algorithm intended to be processed by a machine, making her contributions foundational to the field of computer science. Lovelace also envisioned the potential of computers beyond mere calculation, predicting their ability to manipulate symbols and create art and music.
