This is a lino block print of Countess, Lady Ada Lovelace (1815-1852), who published the first computer program. She worked together with Charles Babbage, the inventor of the Difference Engine and the Analytical Engine (the first - analogue! - computers), correcting his notes on how to calculate Bernoulli Numbers with the Analytical Engine. More importantly, she (a great communicator, daughter of mad, bad and dangerous to know poet Lord Byron) was able to understand and explain the workings of the analytical engine and the potential of computing machines. Her comments seem visionary to the modern reader. Babbage called her the Enchantress of Numbers and the Princess of Parallelograms.

The print is in gold, purple and turquoise water-based block printing ink on mauve Japanese gampi paper 15.25 inches x 10.5 inches (26,7 cm par 38,7 cm). The first edtion is limited to 8 prints.

The print shows Lady Ada, based on engravings made during her lifetime, before gears of the Charles Babbage Analytical Engine, based on one of his blueprints. Depicted around the gears are equations relating how to calculate Bernouilli Numbers. This is not only because Ada published how to do this MECHANICALLY, but because she forsaw that machines would one day be able to work with SYMBOLS (like those used, for instance) and not just numbers!
(carving three equations is a new level of insanity for me)

C'est une gravure d'Augusta Ada King, comtesse Lovelace ou simplement Ada Lovelace, née à Londres le 10 décembre 1815 et morte à Londres le 27 novembre 1852. Elle est principalement connue pour avoir écrit une description de la machine analytique de Charles Babbage, un ancêtre mécanique de l'ordinateur. Elle passa neuf mois, entre 1842 et 1843 à traduire pour Babbage le mémoire du mathématicien italien Federico Luigi, comte de Menabrea (1809-1896) sur la machine analytique. Elle ajouta à cet article plusieurs notes qui mentionnaient une méthode très détaillée pour calculer les nombres de Bernoulli avec la machine. Ces notes sont considérées par les historiens comme le premier programme informatique au monde! Elle a même put faire l'hypothèse que « La machine pourrait composer de manière scientifique et élaborer des morceaux de musique de n'importe quels longueur ou degré de complexité.»

La gravure montre Ada devant un image de la machine analytique de Charles Babbage et des formules pour calculer les nombres de Bernouilli. C`est imprimé en or, violet et turquoise sur papier mauve, japonais, 10,5 par 15,25 pouce (26,7 cm par 38,7 cm) en tailleur. Il y a 8 gravures dans l'édition premier.
