Ada Lovelace

unusual a figure to be in any sense ‘typical’ in the short list of women in mathematics. Women emerge to take a place as major figures in this history almost at its last moment. And while one can and should find space for the skilled amateur Ada Byron, Countess of Lovelace as a ‘joint forerunner’ of the computer, or for Sofia Kovalevskaya as a high-quality contributor to nineteenth-century analysis, the place of Noether, like that of Ramanujan, goes well beyond the category of prizes awarded in a special

binaire. Or, c’est la puissance de la base e e binaire qui va permettre une nouvelle suite de d´veloppements importants. Georges e 3 Ada Lovelace, math´maticienne et amie de Babbage, ´crit ainsi un algorithme pour la machine e e de Babbage qui aurait permis de calculer les nombres de Bernouilly : mˆme si la machine analye tique n’a jamais ´t´ produite, Ada est cependant consid´r´e comme la premi`re « programmeuse ee ee e informatique. » 150 6.
