The first woman in France to get a Ph.D. Any guesses?

On this very day (25th June- 1903), 113 years ago...... Marie Curie defended her thesis on radioactive substance at University of Sorbonne- France, thus becoming the first woman in France to obtain a Ph.D. degree..... Seeing this, I get motivation that I will also successfully defend my thesis in few years...   :)
