After a brief return to Charleston, Benjamin moved to New Orleans, Louisiana. According to Rabbi Bertram W. Korn's volume on that city's Jews, he "arrived in New Orleans in 1828, with no visible assets other than the wit, charm, omnivorous mind and boundless energy with which he would find his place in the sun". After working in a mercantile business, he became a clerk for a law firm, where he began to read law, studying as an apprentice. Knowledge of French was important in practicing law in Louisiana, as the state's code was (and is still) based on French and Spanish law. To earn money, he tutored French Creoles in English; he taught the language to Natalie Bauché de St. Martin on the condition that she teach him French. In late 1832, at age 21, he was admitted to the bar.
