Augusta Ada King was an English writer and mathematician who is considered to be the world’s first computer programmer. This title is given to her based on a theoretical, algorithm-based program she created to run on Charles Babbage’s equally theoretical Analytical Engine. The program was sound in that it would have run if the machine had ever been built.
Born December 10, 1815, with the name Augusta Ada Byron, she was the only legitimate child of the poet Lord Byron and his wife Anne Isabella Milbanke. Lord Byron and Anne Milbanke separated shortly after Ada was born. Ada's mother pushed her toward mathematics in an attempt to defeat the girl's father's poetic passions. This backing in mathematics helped Ada establish a friendship with Charles Babbage in 1833. Her full influence on his work is not known, but in 1842 she translated the work of Louis Menebrea, an Italian mathematician, and created additional notes of her own to accompany it. In these notes, Ada not only anticipated the general-purpose computer, but also wrote a program for calculating Bernoulli numbers using the Analytical Engine. Ada became the Countess of Lovelace when her husband, William King, inherited the Earldom of Lovelace. Her work as a programmer was not widely known, but has since been commemorated in many ways. In 1977, the U.S. Department of Defense named a computer language in her honor.
