Ada Lovelace

(10 December 1815 – 27 November 1852) was an English mathematician and writer chiefly known for her work on Charles Babbage's early mechanical general-purpose computer, the Analytical Engine. Throughout her life, Ada was strongly interested in scientific developments and fads of the day, including phrenology and mesmerism. Even after her famous work with Babbage, Ada continued to work on other projects. In 1844, she commented to a friend Woronzow Greig about her desire to create a mathematical model for how the brain gives rise to thoughts and nerves to feelings ("a calculus of the nervous system").
