Jules Carpentier (1851 – 1921) was a French engineer and inventor.
Jules Carpentier was a student at the French École polytechnique. He bought the Ruhmkorff workshops in Paris when Heinrich Daniel Ruhmkorff died and made it a successful business for building electrical and magnetical devices. From 1890, he started to build photographic and cinematographic cameras. He is the designer of the submarine periscope, and worked at the adjustment of trichromic process of colour photography.
He patented the "Cinématographe", which serves as a film projector and developer in the late 1890s, and built devices from the Lumière Brothers.
Another of his patents, filed in England, was a primary reference of Theodor Scheimpflug, who disclaimed inventing the falsely eponymous Scheimpflug principle.
He died in 1921 in a car accident in Joigny, France.
Jules Carpentier was one of the first manufacturers of various models of Galvanometer that had been designed by Marcel Deprez and Arsène d'Arsonval. In addition, carpentier developed with other people like Eleuthère Mascart, Pellat, Broca, André Blondel, Abraham, Louis Le Chatelier and Callender a series of derivatives of Galvanometer to measure and record intensity, potential tensions and other amounts derived from them. The French engineer and inventor has also contributed to various electrical measurements and the establishment of the necessary rules. Furthermore, for nearly half a century, many electrical measuring instruments took the "Carpentier" mark.
Jules Carpentier took care of the settings of the french engineer Emile Baudot's telegraph system of Posts and Telecommunications. Some devices regulators, translators and printers completed the system thanks to his work and his main collaborators. Thousands of installations "Baudot" were guided workshops to equip Jules Carpentier telegraph networks in France and many foreign countries.
After the invention of the telegraph and the first tests of Marconi, Gustave Ferrie, then captain of Engineering at the service of military telegraph, was commissioned by the Minister of War, Freycinet, to continue to experience more and do more studies to implementation in France of a material that would make a first class military importance. To achieve these successes, Gustave Ferrie sought collaboration as fabricant Carpentier. They studied about building new bases induction coils and mercury switches specially designed for the TSF, and soon established a complete electrical equipment for production of radio waves for downloads powerful capacitors by the age.
