He was born in Bouligneux, Ain, France. He came of a rich family which had renounced the Jewish for the Catholic religion. From the same family sprang the better known Frédéric Ozanam. Though he began the study of theology to please his father, he was more strongly attracted to mathematics, which he mastered without the aid of a teacher. At the age of fifteen he produced a mathematical treatise. Upon the death of his father, he gave up theology after four years of study and began, at Lyon, to give free private instruction in mathematics. Later, as the family property passed entirely to his elder brother, he was reluctantly driven to accept fees for his lessons. Bouligneux is a commune in the French département of Ain. ...
