Du Pont de Nemours summoned Demersan to Talleyrand's house the day after Napoleon's downfall

"Mr. Demersan, Auditor at the Court of Auditors, will go today to the palace of HSH Prince Talleyrand [newly appointed head of the provisional government] before 9 o'clock, to await the orders that will be given to him. The Secretary General of the Provisional Government, Du Pont de Nemours."

An unusual document signed as "Secretary General of the Provisional Government," a government that lasted only one month between the abdication of Napoleon I at Fontainebleau and the return of Louis XVIII to Paris.

Deposed by the Senate the previous day, Napoleon I had abdicated on April 4th in favor of the King of Rome. On April 5th, the day this document was issued, the army responsible for the defense of Paris surrendered to the Austrians. The following day, April 6th, the Emperor abdicated unconditionally, and on the 20th he bid farewell by leaving Fontainebleau for the island of Elba.

Pierre Samuel Du Pont de Nemours had been appointed secretary of the French provisional government in 1814, after Napoleon's abdication.

A year later, he returned to the United States where his son, Eleutherius Irenaeus, had founded one of the world's largest chemical companies, E.I. du Pont de Nemours and Company, specializing in Neoprene, Nylon, Teflon, Kevlar, Lycra, etc., still in operation today.
