1602–1686
Best known for the dramatic Magdeburg hemispheres experiment, this 17th-century inventor helped turn air pressure and the vacuum into something people could see and test. He was also a public servant whose scientific work grew out of a life shaped by war, politics, and rebuilding.

by Otto von Guericke
Born in Magdeburg in 1602, Otto von Guericke was a German natural philosopher, engineer, inventor, and statesman. He studied law and philosophy, then spent much of his public life serving his city, eventually becoming mayor of Magdeburg after the devastation of the Thirty Years' War.
He is remembered above all for pioneering experiments on the vacuum and atmospheric pressure. To carry them out, he developed one of the first effective air pumps and staged the famous Magdeburg hemispheres demonstration, showing the force of air pressure in a way that captured wide attention.
Guericke also explored electrostatics and published his scientific work in Experimenta Nova. His life stands out because he combined civic duty with hands-on experimentation, helping move natural philosophy toward the more public, demonstrable science that followed.
