In page Marquis de Condorcet:

"

Condorcet was born in Ribemont (in present-day Aisne), descended from the ancient family of Caritat, who took their title from the town of Condorcet in Dauphiné, of which they were long-time residents. Fatherless at a young age, he was taken care of by his devoutly religious mother who dressed him as a girl till age eight. He was educated at the Jesuit College in Reims and at the Collège de Navarre in Paris, where he quickly showed his intellectual ability and gained his first public distinctions in mathematics.[1] When he was sixteen, his analytical abilities gained the praise of Jean le Rond d'Alembert and Alexis Clairaut; soon, Condorcet would study under d'Alembert.[citation needed]
