This is an ancient measuring instrument whose pressure-sensitive 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 indicating 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 linked his name, and in 1853 a type of aneroid barometer.
Since ancient times, man, as a farmer and navigator, has observed and attempted to predict the course of the climate. The scientific study of the changes that occur in the atmosphere began in the mid-17th century, in connection with experiments aimed at demonstrating the existence of a vacuum, which the ancient philosophers denied because "nature abhors a vacuum!". Evangelista Torricelli (1608-1647), mathematician and physicist, disciple of Galileo, was the first, in 1643, to build an instrument capable of detecting changes in air pressure. He described his experiment as the result of the discovery that variations in atmospheric pressure are linked to changes in the weather.
