In 1830 Schneider was the bank's agent with the French expeditionary force to Algiers, for which the bank was providing supplies. Schneider met the army's needs from Spanish suppliers, who were cheaper than the French. The project was a great success for the bank.Schneider received a 2% commission on all the merchandise, which gave him enough capital to go into business on his own account as a cloth merchant. On 7 July 1831 he married Valérie Aignan (1812–1861) in Paris. They had three children: Camille, Marie and Paul Henry.
