</ref> Ampère moved to [[Paris]], where he began a tutoring post at the new [[École Polytechnique]] in 1804. Despite his lack of formal qualifications, Ampère was appointed a professor of mathematics at the school in 1809. As well as holding positions at this school until 1828, in 1819 and 1820 Ampère offered courses in [[philosophy]] and [[astronomy]], respectively, at the [[University of Paris]], and in 1824 he was elected to the prestigious chair in [[experimental physics]] at the [[Collège de France]]. In 1814, Ampère was invited to join the class of mathematicians in the new ''Institut Impérial'', the umbrella under which the reformed state Academy of Sciences would sit.

Ampère engaged in a diverse array of scientific inquiries during the years leading up to his election to the academy—writing papers and engaging in topics from mathematics and philosophy to chemistry and astronomy, which was customary among the leading scientific intellectuals of the day. Ampère claimed that "at eighteen years he found three culminating points in his life, his [[First Communion]], the reading of Antoine Leonard Thomas's "Eulogy of Descartes", and the [[Taking of the Bastille]]. On the day of his wife's death he wrote two verses from the [[Psalm]]s, and the prayer, 'O Lord, God of Mercy, unite me in Heaven with those whom you have permitted me to love on earth.' In times of duress he would take refuge in the reading of the [[Bible]] and the [[Fathers of the Church]]."<ref>{{cite web | title = Catholic Encyclopedia | url = http://www.newadvent.org/cathen/01437c.htm| access-date = 29 December 2007 }}</ref>

A lay [[List of lay Catholic scientists|Catholic]], he took for a time into his family the young student [[Frédéric Ozanam]] (1813–1853), one of the founders of the [[Conference of Charity]], later known as the [[Society of Saint Vincent de Paul]].{{citation needed|date=December 2022}} Ozanam would much later be [[Beatification|beatified]] by [[Pope John Paul II]] in 1998. Through Ampère, Ozanam had contact with leaders of the neo-Catholic movement, such as [[François-René de Chateaubriand]], [[Jean-Baptiste Henri Lacordaire]], and [[Charles Forbes René de Montalembert]]. {{citation needed|date=December 2022}}
