|A diagram of the Torricelli barometer, showing Evangelista Torricelli (1644) upending a fully-filled tube of mercury into a larger bowl of mercury, the height of the mercury "column", below the void formed at the top, being the measure of atmospheric press. |
In 1644, Evangelista Torricelli constructed the device, which was generally based on the Berti water column barometer (c.1639) (see: Berti vacuum experiment), itself stimulated into inception from debates over the Galileo vacuum device (1632).
