As it has so often happened in the history of savants and students, there ran in Pinetti's blood a love of the mysterious with that peculiar strain of charalatanism which went to make up the clever performer in old-time magic. Evidently he resigned his duties as a professor for the more picturesque life of the travelling magician, and he is first heard from in this capacity in the French provinces in 1783. His fame quickly carried him to Paris, where in 1784 he appeared before the court of Louis XVI. His arrival was most opportune, for just then all Paris and, for that matter, all Europe had been aroused to a new interest in magic by the brilliant Cagliostro. [Illustration: The only authentic portrait of Pinetti in existence, the only known copy extant being in the Harry Houdini Collection.] From Paris he went to London, playing at the Haymarket and creating a sensation equal to that which he made in France. Later he toured Germany, playing in Berlin and Hamburg. Next he went back to his native land, Italy, but later returned to Germany for a second engagement. In 1789 he appeared in Russia and never left that country. There he married a Russian girl, daughter of a carriage manufacturer. They had two children. Pinetti would have left enormous wealth, but in his later years he became interested in ballooning, the sensation of the hour, and spent his entire fortune on balloon experiments. He died in Bartichoff, Volhinie, aged fifty years. [Illustration: Henri Decremps, the French author who exposed and endeavored to ruin Pinetti, but succeeded only in immortalizing him.] Pinetti was a man of rare inventive genius and almost reconstructed the art of conjuring, so numerous were his inventions. For half a century after his death his successors drew upon Pinetti's inventions and répertoire for their programmes. Naturally such ability aroused bitter jealousies, especially as Pinetti made no attempt to conciliate his contemporaries, either magicians or writers on magic. He issued one book, whose title-page reads: "Amusements Physiques et Differentes Expériences Divertissements, Composées et Executées, tant à Paris que dans les diverses Courts de l'Europe. Par M. Joseph Pinetti de Willedal, Romain, Chevalier de l'Ordre Mérite de Saint-Phillipe, Professeur de Mathématiques et de Physiques, Protégé par toute la Maison Royale de France, Pensionnaire de la Cour de Prusse, etc., 1785."
