Enrico (Henry) Negretti (Como 1817 - London 1879), emigrated to London in 1829, where he attended the London Mechanics Institute, at the same time starting an apprenticeship in a laboratory of precision optical instruments. In 1859 he joined Joseph Zambra (1822-1897), a manufacturer of scientific instruments, and they established the Negretti & Zambra Ltd, with numerous branches in London, and soon they had a good reputation both at home and abroad because of the excellence of their products. In the early years of the company, they limited production to meteorological instruments, or, as they defined them, "philosophical instruments". About in 1857 Negretti & Zambra were commissioned by the British government to investigate about the temperature of the sea along the coasts, to clarify which influence the temperature had on migration and habits of fishes and which were the seasons and temperatures more suitable for fishing. For these investigations, the Negretti & Zambra realized for the Admiral Fitzroy a mercury thermometer that was the most accurate ever made. Towards the end of the nineteenth century, they diversified their products by manufacturing optical instruments such as astronomical and terrestrial telescopes, levels, theodolites, sights, as well as further improvements in barometers and other meteorological instruments. The company passed from father to son until 1946.
Man, as farmer or navigator, has always observed and tried to forecast the changes of weather. Scientific studies about these changes began in the middle ofXVII century, following experiments about the existence of empty, that antique philosophers denied because “nature hates empty!”.
