Ada, Countess of Lovelace was a British mathematician and writer, chiefly known for her work on the Analytical Engine, an early mechanical general-purpose computer invented by Charles Babbage. The engine was to be programmed using punched cards. Lovelace’s notes on the engine include what is recognized as the first algorithm intended to be carried out by a machine. Specifically, she developed an algorithm to calculate a sequence of Bernoulli numbers. As a result, she is often regarded as the first computer programmer. Lovelace was born on December 10, 1815 and died on November 27, 1852 at the age of 36.
