Thanks Dennis, below is an extract from the American National
Biography's life of du Pont. Can you post the descent here?
Eleuthère Irénée du Pont (1771-1834), industrialist, was born in
Paris, France, the son of Pierre Samuel du Pont de Nemours, a
political economist, and Nicole Charlotte Marie Louise Le Dée de
Raucourt. The boy's godfather, Anne Robert Jacques Turgot, who became
comptroller general of finances under Louis XVI, suggested the name in
honor of peace and liberty. Du Pont was raised on his father's estate,
"Bois des Fossés," near Egreville, where he responded with little
enthusiasm to a series of tutors who attempted to educate him. The one
subject that did interest him was explosives, and at age thirteen he
prepared a report on gunpowder for his father. In the fall of 1785 he
entered the Collège Royal in Paris, and two years later Antoine
Lavoisier, a noted chemist and friend of Irénée's father, accepted the
youth as a student in the Régie des Poudres et Salpetres, the
government agency for the manufacture of gunpowder. After a brief
apprenticeship, du Pont took a position at the government powder works
at Essonnes, but when Lavoisier left to become one of the
commissioners of the national treasury, du Pont quit in 1791 to manage
the large publishing house that his father had recently opened in
Paris. Du Pont fell in love with Sophie Madeleine Dalmas and fought
two duels with another suitor to win her hand. His father thought the
daughter of a shopkeeper was beneath the social position he had worked
hard to attain for the family, but Irénée persisted. With his father's
reluctant blessing, they married in 1791.
…. . On 10 August 1792 both father and son were among a small group
that protected the escape of Louis XVI when a mob stormed the
Tuileries… . Despite their efforts on behalf of the king, both du
Ponts favored governmental reform… . Irénée was a member of the pro-
Revolution national guard and supported the Jacobins… . In 1799 the
family sold the publishing house, and … sailed for the United States
… . and proceeded to the home Pierre Samuel had secured in Bergen
Point, New Jersey, across the river from New York. The du Ponts opened
an office in New York City, but it was unclear what their line of
business would be… . [After] a tour of an American powder plant [E I
du Pont] returned to New Jersey believing he had found a business for
the family… . When Jefferson endorsed the idea, Pierre Samuel
reluctantly agreed and sent his sons to France at the beginning of
1801 to secure the necessary equipment and financing. … . Since this
was to be primarily Irénée's venture, the firm was christened E. I. du
Pont de Nemours & Company… . Du Pont's sudden collapse and death in
Philadelphia was blamed, in conflicting reports, on either cholera or
a heart attack. [His company] would grow into one of the [US]'s great
corporate empires. Of his eight children, seven lived to adulthood.
Leadership of the company temporarily passed to his son-in-law Antoine
Bidermann, a twenty-year employee. Bidermann satisfied all remaining
debts by 1837, then reorganized the company as a partnership of all
seven siblings
