Despite a leaning toward literature and history, Frédéric’s father decided on a law career for him and apprenticed him to a local attorney, M. Coulet. In 1831 he entered the Sorbonne in Paris to study law.

Although a law student, in his spare time, the young man pursued the study of language and managed to contribute historical and philosophical articles to the college journal. In the Spring of 1831 Ozanam published his first work of any length, “Reflections on the Doctrine of Saint-Simon,” which was a defense against some false social teaching that was capturing the fancy of young people at the time. His efforts were rewarded with favorable notice from some of the leading social thinkers of the day including Lamartine, Chateaubriand and Jean-Jacques Ampere.

At sixteen the young Ozanam started his course in philosophy and became greatly disturbed by doubts of faith for about a year. However, he was able to survive the ordeal with the help of a wise teacher and guide, Abbe Noirot, who was to exercise a strong influence on Frédéric throughout his life. In the midst of this crisis, he made a promise that if he could see the truth, then he would devote his entire life to its defense. Subsequently he emerged from the crisis with a consolidation of the intellectual bases for his faith, a life commitment to the defense of Truth and a deep sense of compassion for unbelievers.

“I grew rather idle in the fourth class, but I pulled up again in the third. It was then that I made my first Communion. O glad and blessed day! may my right hand wither and my tongue cleave to the roof of my mouth if I ever forget thee! I had changed a good deal by this time; I had become modest, gentle, and docile, more industrious and unhappily rather scrupulous. I still continued proud and impatient.”

“Then I began to learn Latin, and to be naughty; really and truly I believe I never was so wicked as at eight years old. And yet I was being educated by a kind father and a kind mother and an excellent brother; I loved them dearly, and at this period I had no friends outside my family, yet I was obstinate, passionate, disobedient. I was punished, and I rebelled against it. I used to write letters to my mother complaining of my punishments. I was lazy to the last degree, and used to plan all sorts of naughtiness in my mind. This is a true portrait of me as I was first going to school at nine and a half years old. By degrees I improved; emulation cured my laziness. I was very fond of my master; I had some little successes, which encouraged me.”

At seven he suffered the loss of his sister, Elsie, which came as a great grief to him: “At seven years old I had a serious illness, which brought me so near death that everybody said I was saved by a miracle,.not that I wanted kind care, my dear father and mother hardly left my bedside for fifteen days and nights. I was on the point of expiring when suddenly I asked for some beer. I had always disliked beer but it saved me. I recovered, and six months later, my sister, my darling sister, died. Oh! what a grief that was.” -from a letter he wrote at age 16

Frédéric Ozanam was born on April 23, 1813 in Milan, Italy. He was the fifth child of fourteen born to Jean-Antoine-François and Marie Nantas Ozanam, ardent French Catholics of middle-class circumstances. His father had served with distinction as an officer under Napoleon, retiring early to become a tutor and later to practice medicine. When the city of Milan fell to the Austrians in 1815, the Ozanams returned to their native city of Lyon, where Frédéric spent his early years.
