Today's Google Doodle is a tribute to the woman who's considered to be the first computer programmer, Ada Lovelace.
Born on December 10, 1815, Ada was the daughter of Lord Byron and his wife Anne Isabella Byron.
She was interested in science and math, and is best known for her work on Charles Babbage's mechanical general-purpose computer, the Analytical Engine. Her notes on the machine are considered to be the first-ever algorithm encoded to be processed by a machine.
