A maker of barometers, thermometers, and an inventor of scientific instruments of Italian descent, he became famous in Paris, first at 37 rue de la Roquette and then at Place Dauphine, where he was based when making the present barometer. He supplied barometers and other scientific instruments to the Ecole Militaire in 1786; the following year he supplied a tube barometer to British optical instruments manufacturer Peter Dollond (1731-1821). During the Empire his clientele included Sir Benjamin Thompson, Count Rumford, the American born British physicist who in 1813 received a Carcano thermometer vase for measuring the heat of various solids and liquids.
