Ada Lovelace, born as Augusta Ada King, Countess of Lovelace, was an English mathematician and writer who is best known for her work on Charles Babbage's early mechanical general-purpose computer, the Analytical Engine. Her notes on the engine include what is recognized as the first algorithm intended to be processed by a machine, which has led her to be regarded as one of the first computer programmers. Lovelace was born on December 10, 1815, and died at a young age of 36 on November 27, 1852. Despite her brief life, she made significant contributions to the field of computer science.
