Blanc was also for many years president of the
Société des bains de mer de Monaco, of
Monte Carlo, and took a leading part in the administration of the
Monte Carlo Casino.
Persona non grata in Monaco In the later years of his administration of Monte Carlo Casino, his relations with
Louis II, Prince of Monaco, suffered a setback, and he withdrew to
France as someone who had become
persona non grata in Monaco's official circles. While married to Elisabeth Lanxade, his name was also linked to Madame Chinon, whose excessive gambling habits, indulged by Blanc, were widely believed by some observers to be substantially at the origins of the accusations of mismanagement which eventually led to Prince Louis' intervention and termination of his position at Monte Carlo Casino. In the closing years of Blanc's life, up to his death in 1927, he suffered severely from paralysis, said to have been derived mainly from the reported stresses of his experience of dealing with the Monaco authorities. ==Legacy==
