This is an ancient measuring instrument whose pressure-sensing organ is a metal box called a barometric capsule. The capsule contracts or expands as a result of changes in pressure, and its movements are transmitted to an indicator hand via a mechanical system. The development of this type of barometer is due to Bourdon, a French inventor and industrialist (Paris 1808-1884), who had founded a factory for the construction of steam engines in Paris in 1835; in 1849 he invented the metal manometer, to which he attached his name, and in 1853 a type of aneroid barometer.
Since ancient times, humans, as farmers and navigators, have observed and attempted to predict climate change. The scientific study of atmospheric changes began in the mid-17th century, in connection with experiments aimed at demonstrating the existence of a vacuum, which ancient philosophers denied because "nature abhors a vacuum!" Evangelista Torricelli (1608-1647), a mathematician and physicist and disciple of Galileo, was the first, in 1643, to build an instrument capable of detecting changes in air pressure, which he understood to be linked to changes in the weather.
