Le Mas
He continued to play an active role in Parisian social life after the end of the war. He lived in a house called "Le Mas du Gay Savoir" in Sainte-Maxime, which made him an honorary citizen. During the late 1940s, he intervened with the Danish and French security services to secure more lenient treatment for the writer Louis-Ferdinand Céline, who had been imprisoned in Denmark while the French authorities sought his extradition because his openly expressed antisemitism led to charges of collaboration with the occupying Germans and the Vichy régime during the war.
