Denis Diderot
Co-founder and chief editor of the Encyclopédie, a key figure of the Enlightenment.
Denis Diderot (5 October 1713 – 31 July 1784) was a French philosopher, art critic, and writer, best known for serving as co-founder, chief editor, and contributor to the *Encyclopédie* along with Jean le Rond d'Alembert. He was a prominent figure during the Age of Enlightenment. Born in Langres, Champagne, to a cutler and his wife, Diderot was one of five siblings, though only three survived to adulthood. He greatly admired his sister Denise, whom he called "a female Socrates." After beginning his education at a Jesuit college in Langres, he earned a Master of Arts from the University of Paris in 1732. He briefly considered the clergy and then studied law, but by the early 1740s he decided to become a writer and translator. His father disowned him for refusing a learned profession, and Diderot lived a bohemian existence for the next decade. In 1742 he befriended Jean-Jacques Rousseau at a café. He married Antoinette Champion in 1743, further alienating his father, who disapproved of her low social standing and lack of dowry. They had one surviving child, a daughter named Angélique. Diderot was unfaithful to his wife, having affairs with several women, including Sophie Volland, to whom he wrote candid letters considered literary treasures. The death of his sister Angélique, a nun, in 1749 may have influenced his views on religion and inspired his novel *La Religieuse*. His earliest works included translations, and in 1746 he wrote his first original work, *Philosophical Thoughts*, arguing for a harmony between reason and feeling. Diderot co-created the *Encyclopédie* in 1751. It was the first encyclopedia to include many named contributors and to describe the mechanical arts. Its secular tone, skeptical of Biblical miracles, angered religious and government authorities; the Catholic Church banned it in 1758, and the French government followed in 1759, though the ban was not strictly enforced. Many contributors left due to controversies, and some were jailed. D'Alembert left in 1759, making Diderot the sole editor and main contributor, writing around 7,000 articles. He continued until 1765, growing despondent and feeling the project might have been a waste, though it is considered a forerunner of the French Revolution. Diderot struggled financially and was passed over for the Académie Française. In 1766, Russian Empress Catherine the Great bought his 3,000-vo

Lore & Background
Diderot studied philosophy at a Jesuit college, then considered working in the church clergy before briefly studying law. When he decided to become a writer in 1734, his father disowned him. He lived a bohemian existence for the next decade. In the 1740s he wrote many of his best-known works in fiction and non-fiction, including the 1748 novel Les Bijoux indiscrets (The Indiscreet Jewels). In 1751 Diderot co-created the Encyclopédie with Jean le Rond d'Alembert. It was the first encyclopedia to include contributions from many named contributors and the first to describe the mechanical arts. Its secular tone, which included articles skeptical about Biblical miracles, angered both religious and government authorities; in 1758 it was banned by the Catholic Church and, in 1759, the French government banned it as well, although this ban was not strictly enforced. Many of the initial contributors to the Encyclopédie left the project as a result of its controversies and some were even jailed. D'Alembert left in 1759, making Diderot the sole editor. Diderot also became the main contributor, writing around 7,000 articles. He continued working on the project until 1765. He was increasingly despondent about the Encyclopédie by the end of his involvement in it and felt that the entire project might have been a waste. Nevertheless, the Encyclopédie is considered one of the forerunners of the French Revolution. Diderot struggled financially throughout most of his career and received very little official recognition of his merit, including being passed over for membership in the Académie Française. His fortunes improved significantly in 1766, when Russian Empress Catherine the Great, who had heard of his financial troubles, bought his 3,000-volume personal library, amassed during his work on the Encyclopédie, for 15,000 livres, and offered him in addition a thousand more livres per year to serve as its custodian while he lived. He received 50 years' 'salary' up front from her, and stayed five months at her court in Saint Petersburg in 1773 and 1774, sharing discussions and writing essays on various topics for her several times a week. Diderot's literary reputation during his life rested primarily on his plays and his contributions to the Encyclopédie; many of his most important works, including Jacques the Fatalist, Rameau's Nephew, Paradox of the Actor, and D'Alembert's D
Reader's Guide
Denis Diderot was born in Langres, Champagne. His parents were Didier Diderot, a cutler, maître coutelier, and Angélique Vigneron. Of Denis' five siblings, three survived to adulthood: Denise Diderot, their youngest brother Pierre-Didier Diderot and, their sister Angélique Diderot. Denis Diderot greatly admired his sister Denise, sometimes referring to her as 'a female Socrates'. Diderot began his formal education at a Jesuit college in Langres. In 1732 he received the degree of Master of Arts from the University of Paris. He abandoned the idea of entering the clergy in 1735 and, instead, decided to study at the Paris Law Faculty. His study of law was short-lived and in the early 1740s he decided to become a writer and translator. Because of his refusal to enter one of the learned professions, he was disowned by his father and, for the next ten years, he lived a bohemian existence. In 1742 he formed a friendship with Jean-Jacques Rousseau, whom he met while watching games of chess and drinking coffee at the Café de la Régence. In October 1743, he further alienated his father by marrying Antoinette Champion (1710–1796), a devout Catholic. Diderot senior considered the match inappropriate, given Champion's low social standing, poor education, fatherless status, and lack of a dowry. She was about three years older than Diderot. She bore Diderot one surviving child, a girl, named Angélique, after both Diderot's dead mother and his sister. The death in 1749 of his sister Angélique, a nun, in her convent, may have affected Diderot's opinion of religion. She is assumed to have been the inspiration for his novel about a nun, La Religieuse, in which he depicts a woman who is forced to enter a convent, where she suffers at the hands of her fellow nuns. Diderot was unfaithful to his wife, and had affairs with Anne-Gabrielle Babuty (who would marry and later divorce the artist Jean-Baptiste Greuze), Madeleine de Puisieux, Sophie Volland, and Mme de Maux (Jeanne-Catherine de Maux), to whom he wrote numerous surviving letters and who eventually left him for a younger man. Diderot's letters to Sophie Volland are known for their candor and are regarded to be 'among the literary treasures of the eighteenth century'. Diderot's earliest works included a translation of Temple Stanyan's History of Greece (1743). In 1745, he published a translation of Shaftesbury's Inquiry Concer
