His family, slave owners based in
Bordeaux, France, held interests in sugar plantations in Haiti including Bellevue, one of the largest in the world. His grandfather, also named Pierre de Bauduy, was a captain of the French militia in Haiti, then known as
Saint-Domingue. When he married Marie Madeleine de Goiran, her dowry included 52 slaves and 10,000
French livres. A letter dated September 26, 1769, reports that each member of the family received sugar worth 550,000 livres. A letter in June 1770 estimated losses caused by a drought at 600,000 livres. and the
Cathedral of Saint Peter. Pierre and Louis Bauduy were close friends of Victor du Pont de Nemours, who introduced them to his brother
Éleuthère Irénée du Pont de Nemours, who had arrived from France at the end of 1799. The articles of partnership for E.I. du Pont de Nemours & Company were signed in Paris on April 21, 1801. Pierre Bauduy signed later and purchased four of the 18 shares. The company, based in Wilmington, focused on military supplies, initially providing woolen uniforms for French forces aiming to retake Haiti. Those included Pierre's brother, by then a captain in the French Army. Pierre promoted the use of merino wool, newly introduced to the United States by
David Humphreys. Several letters report the cooling of relations between the partners, and Bauduy withdrew from the company in December 1814, then sold his shares in DuPont on February 18, 1815, at the end of the
War of 1812. He left to found a sugar factory in
Matanzas Province, Cuba. In 1827, the family settled in New York, and then in 1829 moved to Eden Park. He later moved back to Cuba, where he obtained Spanish citizenship and died of cholera at Havana in 1833. ==References==
