Ada Lovelace…. via magictransistor:
Augusta Ada King, Countess of Lovelace, was an English mathematician and writer chiefly known for her work on Charles Babbage's early mechanical general-purpose computer, the Analytical Engine. Her notes on the engine include what is recognised as the first algorithm intended to be processed by a machine. Because of this, she is often described as the world’s first computer programmer.
