Coined/History
The first barometer was invented in 1644, by Talian mathematician and physicist Evangelista Toriricelli (1608-1647) and was known
as the “Torriceli tube”. However some
reports attribute its invention to Italian scientist Gasparo Berti in the early
1640s. Torriceli’s barometer contained mercury as it had been suggested by
Torriceli’s friend Galileo Galilei (1564-1642). A water barometer was created later as there some
written records around 1700. In 1843 Lucien Vidie invented the first fluid-less barometer known today as “aneroid barometer”.
