Work and Legacy Around the age of 17, Ada met Charles Babbage, a mathematician and inventor. Ada was fascinated by Babbage’s ideas. Known as the father of the computer, he invented the difference engine, which was meant to perform mathematical calculations. Babbage also created plans for another device known as the analytical engine, designed to handle more complex calculations.

Ada was later asked to translate an article on Babbage’s analytical engine that had been written by Italian engineer Luigi Federico Menabrea for a Swiss journal. She not only translated the original French text in English, but also added her own thoughts and ideas on the machine. Her notes ended up being three times longer than the original article.
