The daughter of English poet Lord Byron, Ada Lovelace was reportedly tutored in maths and sciences because her mother believed that rigorous study would prevent Lovelace from developing her father’s moody disposition. When she was around 17, Lovelace met Charles Babbage, who is credited with inventing the first mathematical computer. In 1842, Lovelace was asked to translate an article about Babbage’s “Analytical Engine.” She did, but she also added her own extensive theories about the machine. In her notes, Lovelace described how codes could be created that would allow the engine to process not only numbers, but also letters and symbols. She also proposed an algorithm for calculating a sequence of Bernoulli numbers, which is said to be history’s first piece of computer code.
