Denis Diderot was a central figure of the French Enlightenment whose diverse intellectual pursuits spanned philosophy, literature, and art criticism. Born in 1713, he initially studied philosophy at a Jesuit college and briefly pursued law before committing to a literary career in 1734. This decision led to estrangement from his father and a decade of bohemian living. During the 1740s, Diderot began publishing notable works of fiction and non-fiction, including his 1748 novel Les Bijoux indiscrets.
Diderot's most monumental achievement began in 1751 when he co-created the Encyclopédie alongside Jean le Rond d'Alembert. Designed as a comprehensive compendium of human knowledge, it was revolutionary for its secular tone, skepticism toward religious miracles, and inclusion of the mechanical arts. Despite facing bans from both the Catholic Church and the French government, Diderot persevered. When d'Alembert and other contributors abandoned the project due to controversy, Diderot became the sole editor and primary contributor, personally authoring approximately 7,000 articles until his involvement ended in 1765.
Despite his immense labor, Diderot faced financial hardship and lacked official recognition in France. His financial situation improved dramatically in 1766 when Empress Catherine the Great of Russia purchased his library and hired him as its well-paid custodian, leading to a brief residency at her court in Saint Petersburg. While Diderot was known in his lifetime primarily for his plays and the Encyclopédie, many of his most celebrated literary and philosophical works—such as Jacques the Fatalist, Rameau's Nephew, and D'Alembert's Dream—were published posthumously, cementing his legacy as a pioneering modern thinker.
