The Palazzo Visconti di Modrone in Milan, where he grew up, had its own small private theater and the children participated in its performances. The family also had their own box in the La Scala opera house. Luchino studied cello with the Italian cellist and composer Lorenzo de Paolis (1890–1965) and met the composer Giacomo Puccini, the conductor Arturo Toscanini and the writer Gabriele D'Annunzio. Visconti found literature by reading Proust's In Search of Lost Time, later a lifelong film project that he never realized. Before he started his film career, he was passionate about training racehorses in his own stable. An engagement concluded in 1935 with Princess Irma of Windisch-Graetz raised concerns with her father, Prince Hugo, whereupon Visconti broke it off. Wartime resistance activity During World War II, Visconti joined the Italian Communist Party, which he considered to be the only effective opponent of Italian Fascism. While in his early years he had been impressed by such aesthetic aspects of the solemn parades of the National Fascist Party as marching in columns in boots and uniform, he had now come to hate the Mussolini regime. He accused the bourgeoisie of treason to tyranny, and following the Badoglio Proclamation, began working with the Italian resistance. He supported the communists' partisan fight at risk of death; his villa in Rome became a meeting place for oppositional artists. After the king's flight in autumn 1943 and the intervention of the Germans, he went into hiding in the mountains, at Settefrati, under the nom de guerre Alfredo Guidi. Visconti helped English and American prisoners of war hide after they had escaped, and also gave shelter to partisans in his house in Rome, with the help of actress María Denis. After the German occupation of Rome in April 1944, Visconti was arrested and detained by the anti-partisan Pietro Koch and sentenced to execution by firing squad. He was only saved from death by Denis' last-minute intervention. After the war, Visconti testified against Koch, who was himself convicted and executed. Career Films He began his film-making career as a set dresser on Jean Renoir's Partie de campagne (1936) through the intercession of their common friend Coco Chanel. After a short tour of the United States, where he visited Hollywood, he returned to Italy to be Renoir's assistant again, this time for Tosca (1941), a production that was interrupted and later completed by German director
