Otto von Guericke

Otto von Guericke was a 17th-century German scientist and inventor known for pioneering experiments in physics, especially involving air pressure and vacuums. He demonstrated that a vacuum could create powerful forces by showing that two metal hemispheres sealed and evacuated of air could only be separated with great effort, highlighting the strength of atmospheric pressure. His work laid foundational principles for the study of vacuum and pressure, influencing future scientific developments. Guericke's experiments helped advance understanding of how gases behave and contributed to the emerging field of pneumatics.
