Ada is a computer language developed originally for DOD contracts. It has rather a lot of features.
During early development, the language was called Green. It is now named after Augusta Ada King[L1 ], Countess Lovelace, (it is most definitely not an acronym) who was AIUI a female mathematician in the 19th centuary. She was a daughter of the mathematician Annabella Milbanke, Baroness Wenthworth, and George Gordon, Lord Byron, (the poet, whom Ada never met) and was a collaborator of Charles Babbage; her work on his Analytical Engine (? - not the Difference Engine but the successor machine) has made her generally accepted as being the world's first computer programmer.
