Did Blaise Pascal invent the aneroid barometer?

Answer 1

Blaise Pascal did not invent the aneroid barometer. Pascal had heard of experiments performed by Evangelista Torricelli using Mercury barometers and duplicated this experiment in order to provide further evidence of the existence of vacuums. An aneroid barometer is a barometer that does not employ the use of liquid, mercury in this case. The idea for the aneroid barometer was recorded as being first conceived by German philosopher and mathematician Gottfried Leibniz around 1700. The actual first general use application was created by French inventor Lucien Vidie around 1843, almost 150 years later.
