Pierre Choderlos de Laclos

Pierre Ambroise François Choderlos de Laclos (French: [pjɛʁ ɑ̃brwaːz ʃɔdɛʁlo də laklo]; 18 October 1741 – 5 September 1803) was a French novelist, official, freemason and army general, best known for writing the epistolary novel Les Liaisons dangereuses (Dangerous Liaisons) (1782).
A unique case in French literature, he was for a long time considered to be as scandalous a writer as the Marquis de Sade or Nicolas-Edme Rétif. He was a military officer with no illusions about human relations, and an amateur writer; however, his initial plan was to "write a work which departed from the ordinary, which made a noise, and which would remain on earth after his death"; from this point of view he mostly attained his goals, with the fame of his masterwork Les Liaisons dangereuses. It is one of the masterpieces of novelistic literature of the 18th century, which explores the amorous intrigues of the aristocracy. It has inspired a large number of critical and analytic commentaries, plays, and films.

Born in Amiens into a bourgeois family, in 1760 Laclos began studies at the École royale d'artillerie de La Fère, ancestor of the École Polytechnique. As a young lieutenant he briefly served in a garrison at La Rochelle until the end of the Seven Years' War (1763). Postings to Strasbourg (1765–1769), Grenoble (1769–1775) and Besançon (1775–1776) followed.

In 1763 Laclos became a freemason in "L'Union" military lodge in Toul.

Despite a promotion to the rank of captain (1771), Laclos grew increasingly bored with his artillery garrison duties and with the company of soldiers; he began to devote his free time to writing. His first works, several light poems, appeared in the Almanach des Muses. Later he wrote an opéra comique, Ernestine, inspired by a novel by Marie Jeanne Riccoboni. Its premiere on 19 July 1777, in the presence of Queen Marie Antoinette, proved a failure. In the same year he established a new artillery school in Valence, which would include Napoleon Bonaparte among its students in the mid 1780s. On his return to Besançon in 1778 Laclos was promoted second captain of the Engineers. In this period he wrote several works which showed his great admiration of Jean-Jacques Rousseau (1712-1778).

In 1776 Laclos requested and received affiliation with the "Henri IV" lodge in Paris. There he helped Louis Philippe II, Duke of Orléans leading the Grand Orient of France. In 1777, in front of the Grand Orient's dignitaries, he delivered what is considered as the first feminist speech by a man, supporting the initiation of women.

In 1779 he was sent to Île-d'Aix (in present-day Charente-Maritime) to assist Marc René, marquis de Montalembert in the construction of fortifications there against the British. However, he spent most of his time writing his new epistolary novel, Les Liaisons dangereuses, as well as a Letter to Madame de Montalembert. When he asked for and received six months of vacation, he spent the time in Paris, writing.

Durand Neveu published Les Liaisons Dangereuses in four volumes on 23 March 1782; it became a widespread success (1,000 copies sold in a month, an exceptional result for the time). Laclos was immediately ordered to return to his garrison in Brittany; in 1783 he was sent to La Rochelle to collaborate in the construction of the new arsenal. Here he met Marie-Soulange Duperré, 18 years his junior, whom he would marry in 1786. The following year he began a project of numbering the streets of Paris.

In 1788 Laclos left the army, entering the service of Louis Philippe, Duke of Orléans, for whom, after the outbreak of the French Revolution in 1789, he carried forward with intense diplomatic activity. Captured by Republican ideals, he left the Duke to obtain a place as commissar in the Ministry of War. His reorganization has been credited as having a role in the French Revolutionary Army's victory in the Battle of Valmy (20 September 1792). Later, after the desertion (April 1793) of general Charles François Dumouriez, he was however arrested as an Orleaniste, being freed after the Thermidorian Reaction of 27 July 1794.

He thenceforth spent some time in ballistic studies, which led him to the invention of the modern artillery shell. In 1795 he requested of the Committee of Public Safety reintegration in the army, a request which the Committee ignored. His attempts to obtain a diplomatic position and to found a bank also proved unsuccessful. Eventually, Laclos met the young general and recently appointed (November 1799) First Consul, Napoleon Bonaparte, and joined his party. On 16 January 1800 he was reinstated in the Army as Brigadier General in the Army of the Rhine; he took part in the Battle of Biberach (9 May 1800).

Made commander-in-chief of Reserve Artillery in Italy (1803), Laclos died shortly afterward in the former convent of St. Francis of Assisi at Taranto, probably of dysentery and malaria. He was buried in the fort still bearing his name (Forte de Laclos) in the Isola di San Paolo near the city, built under his direction. Following the restoration of the House of Bourbon in southern Italy in 1815, his burial tomb was destroyed; it is believed that his bones were tossed into the sea.
