Lonis Antoinc Fauvclet De Bourrienne, private secretary of Napoleon I., born at Sens, July 9, 1769, died in Caen, Feb. 7, 1834. He was the schoolmate of Napoleon at the military institute of Brienne, and subsequently spent some time at Vienna, Leipsic, and Warsaw. After his return to Paris he renewed his intimacy with Napoleon, then a poor and friendless officer; but the decisive turn taken by the revolutionary movement after June 20, 1792, drove him back to Germany. In 1795 he again returned to Paris, and there again met Napoleon, who however at that time treated him coldly; but toward the end of 1796 he was installed as his private secretary. After the 18th Brumaire Bourrienne received the title of councillor of state, was lodged at the Tuileries, and admitted to the first consul's family circle. In 1802 the army contractor Coulon, whose partner Bourrienne had secretly become, and for whom he had procured the lucrative business of supplying the whole cavalry equipment, failed with a deficit of 3,000,000 francs; the chief of the house disappeared, and Bourrienne was banished to Hamburg. He was afterward appointed to watch in that city over the strict execution of Napoleon's continental system.

Accusations of peculation arising against him from the Hamburg senate, from which he had obtained 2,000,000 francs, and from the emperor Alexander, whose relative the duke of Mecklenburg he had also mulcted, Napoleon sent a commission to inquire into his conduct, and ordered him to refund 1,000,000 francs to the imperial treasury. Thus, a disgraced and ruined man, he lived at Paris until Napoleon's downfall in 1814, when this amount was restored to him by the French provisional government, and he was appointed postmaster general, but removed by Louis XVIIL, who, however, at the "first rumor of Napoleon's return from Elba, made him prefect of the Paris police, a post he held for eight days. As Napoleon, in his decree dated Lyons, March 13, had exempted him from the general amnesty, he followed Louis XVIIL to Ghent, was thence despatched to Hamburg, and created on his return to Paris state councillor, and subsequently minister of state. His pecuniary embarrassments forced him in 1828 to seek a refuge in Belgium, on an estate of the duchess of Bran-cas at Fontaine l'Eveque, not far from Charle-roy. Here, with the assistance of M. de Ville-marest and others, he prepared Memoircs sur Napoleon, le directoirc, le consulate Vempire et la restauration (10 vols. 8vo, 1829-'31; English translation, 4 vols., Edinburgh, 1831). This work, which throws much light upon Napoleon's career, led to a counter-publication entitled Bourrienne et ses erreurs volontaires et involontaires (2 vols., Paris, 1830). The loss of his fortune, said to have been caused by the revolution of 1830, drove him mad, and the last two years of his life were spent in an asylum, where he died from apoplexy.
