Charles-François Dupuis rose from humble origins in Trie-Château to influence the intellectual landscape of late 18th-century France. Through his work as an astronomer, legal expert, and politician, he challenged established religious chronologies. His contributions to academic scholarship and his active participation in the legislative bodies during the French Revolution marked a career defined by diverse, unconventional intellectual pursuits.
Early Academic Development
Born in 1742, Dupuis developed an early aptitude for geometry and trigonometry while living near the Château de La Roche-Guyon. His skills earned him the patronage of the Duke of La Rochefoucauld, facilitating his education at the Collège d'Harcourt in Paris. He proved to be a prolific student, securing numerous distinctions in the Concours général and completing a five-year course of study at the University of Paris. By 1767, he successfully passed the agrégation and began a two-decade tenure teaching rhetoric at the Collège de Lisieux.

Beyond his teaching duties, Dupuis explored various scientific fields. In 1778, alongside geographer Jean-Baptiste Fortin, he attempted to create an optical telegraph system by utilizing shutter signals between Belleville and Bagneux. This early experimental work served as a precursor to future semaphore developments. Simultaneously, he deepened his understanding of astronomy through lectures by Jérôme Lalande at the Collège Royal and qualified as an avocat en parlement in 1770.
Philosophy of Religion and Celestial Myths
Dupuis is best recognized for his systematic analysis of religious history, arguing that ancient myths were allegorical representations of celestial movements and seasonal changes. He published these findings in various journals throughout the 1780s, sparking debates with contemporaries like Jean Sylvain Bailly and Guillaume Le Gentil. His analysis of axial precession led him to suggest that the zodiac originated long before traditional dates for the Creation, a radical claim that complicated his path to the Académie des Inscriptions et Belles-Lettres.
Political Engagement and Later Career
During the French Revolution, Dupuis transitioned into active politics. He served as a député de Seine-et-Oise in the National Convention from 1792 to 1797 and returned to the position between 1799 and 1803. During this time, he contributed to the development of the French Republican calendar. He remained associated with the Collège de France as a professor from 1787 until his death in 1809 in Échevannes, eventually receiving the distinction of Knight of the Legion of Honour for his service.
