Early life
De Mun was born in Port-au-Prince, Saint-Domingue to an aristocratic family originating from the Southwest of France. He was educated in Paris, before moving to St. Louis in 1800.Trading career
In September 1815, de Mun went with Auguste Pierre Chouteau and his brother Pierre Chouteau Jr. to the Rocky Mountains on an expedition, to trade horses with the Arapahos and Comanche tribes. After a while, however, the trade began to dwindle and they ceased operations. While trading in Mexico, de Mun was imprisoned alongside A. P. Chouteau for 48 days in Santa Fe, leading the group to file a claim against the Mexican government for confiscated goods worth $30,000. Payment for the claim was not obtained until 1851, through an act of Congress.In 1817, de Mun opened a trading business with Auguste Pierre Chouteau in St. Louis, known as A. P. Chouteau, de Mun & Co., or Chouteau, De Mun & Sarpy. On 14 September 1818, de Mun dropped out of the business.
