He brought in his sons Victor (1892-1954), Albert (1894-1963) and Moïse (Mouche) (1897-1977) to the family business.[1] After the death of Victor and Albert's departure for Algeria in the 1930s, Moise succeeded his father and renamed the business Les fils de J. Chemla (Sons of Jacob Chemla), which operated as a family business until 1966. In the 1960s, President of Tunisia Habib Bourguiba contracted the company to install ceramic panels at Carthage Palace.
