Lo Duca was born in Milan in 1911. At the age of 16, he wrote his first book, The Platinum Sphere, launched by Marinetti, the father of futurism. In France, it will be prefaced by Marcel Griaule and is four years ahead of Brave New World by Aldous Huxley, to which it has often been compared. From the 1930s, Lo Duca only wrote in French. He first became known for his writings on art: Giorgio de Chirico, Rousseau Le Douanier, Eros im Bild (prefaced by George Bataille); and later by his studies on cinema (History of Cinema which will be translated into twelve languages), on the art of comic strips (Manuel des confesseurs and Krafft-Ebing) and on erotology (L'Erotisme au cinema - 1945, The History of Eroticism - 1968 -, Dictionary of sexology - 1972 -). All in all, a resolutely marginal work, which uniquely combines erudition, eroticism and imagination. If only one had to be selected, his admirers, André Breton, Jean Cocteau, Jean Dutourd, Marcel Pagnol, George Bataille..., would shout with one voice: The Secret Journal of Napoleon Bonaparte, edited by JJ Pauvert in 1948, then republished by Editions Phébus in 1997.
