Otto von Guericke Edit Profile
Having studied law at Leipzig, Helmstadt and Jena, and mathematics, especially geometry and mechanics, at Leiden, he visited France and England, and in 1636 became engineer-in-chief at Erfurt.
His studies revealed that light travels through a vacuum but sound does not. In 1654, in a famous series of experiments that were performed before Emperor Ferdinand III at Regensburg, Guericke placed two copper bowls (Magdeburg hemispheres) together to form a hollow sphere about 35. 5 cm (14 inches) in diameter. After he had removed the air from the sphere, horses were unable to pull the bowls apart, even though they were held together only by the air around them. The tremendous force that air pressure exerts was thus first demonstrated.
In 1672 he discovered that the electricity thus produced could cause the surface of the sulfur ball to glow; hence, he became the first man to view electroluminescence. Guericke also studied astronomy and predicted that comets would return regularly from outer space.
