Algeria's new republic retained the most useful colonial shipping magnate. [fact]
Then there was Laurent Schiaffino, who controlled probably the biggest fortune in Algeria, including most of its shipping. Although a third-generation Neapolitan, Schiaffino revealed few of the extrovert characteristics one might have expected; with a greyish complexion, he was a cold and retiring personality with a meticulous knowledge of the marine world, but seldom seen outside family or business circles. He too was a senator for Algiers, and owner of the Dépêche Algérienne, which held a reputation principally for being "anti", that is to say, "anti" any measure of liberalisation. (Yet, after 1962, because of the efficiency and indispensability of his marine fleet, he was the only one of the grands colons to be invited to stay on by the new Algerian republic.)
