Lady Ada Day celebrates the life of Ada Lovelace, daughter of the poet Lord Byron and a woman credited as the world’s first computer programmer. She reportedly had no contact with her father and took up an interest in science instead of a life of letters.
From FindingAda.com, a web site that celebrates the life of Ada and female scientists everywhere:
In 1842 Lovelace translated a short article describing the Analytical Engine by the Italian mathematician Luigi Menabrea, for publication in England. (Mathematician Charles) Babbage asked her to expand the article, “as she understood the machine so well.” The final article is over three times the length of the original and contains several early ‘computer programs,’ as well as strikingly prescient observations on the potential uses of the machine, including the manipulation of symbols and creation of music. Although Babbage and his assistants had sketched out programs for his engine before, Lovelace’s are the most elaborate and complete, and the first to be published; so she is often referred to as “the first computer programmer.” Babbage himself “spoke highly of her mathematical powers, and of her peculiar capability — higher he said than of any one he knew, to prepare the descriptions connected with his calculating machine.”
Good call on that father-daughter relationship, Lady Ada! Probably spared you a(nother) world of grief in the end.
