The use of vacuum traces back to Otto von Guericke. As a scientist and inventor, he developed a basic vacuum Pump in 1650 that could remove air from a vessel.
To publically demonstrate vacuum science, two large copper hemispheres were sealed together and evacuated. The hemispheres now held together by atmospheric pressure could not be separated by teams of horses. This first public demonstration showed the effects of air pressure and high vacuum.
