Ada has two origins. In Old Germanic, it is a short form of names beginning with adel, meaning "noble" — like Adelaide, Adeline, or Adela. In Hebrew, Adah (עָדָה) appears in the Book of Genesis as one of the wives of Lamech and means "adornment" or "ornament."
Ada has been borne by some of the most consequential figures in the history of computing: Augusta Ada King, Countess of Lovelace — daughter of Lord Byron — is recognised as the first computer programmer for her notes on Charles Babbage's Analytical Engine in the 1840s. The Ada programming language, used in aerospace and defence systems, is named after her.
Three short letters, two ancient origins, and one of the most important women in technological history.
Ada reduces to one — the number of independence, leadership, and originality. The number of the first.
