William Gilbert (1544 - 1603)

William Gilbert

William Gilbert was a British physicist and medical scientist famous for pioneering the study of magnetic and electrical phenomena.

After receiving a medical degree, Gilbert settled in London and began his research. In his major work De Magnete, Magneticisque Corporibus, et de Magno Magnete Tellure (On Magnetic Stones and Magnetic Bodies and the Great Magnet of the Earth), published in 1600, the scientist describes in detail his studies of magnetic bodies and electric attraction.

After years of experimentation, he came to the conclusion that the compass arrow points north-south and downward because the Earth acts as a rod magnet. He was the first to use the terms electric attraction, electric force, and magnetic pole. Gilbert came to believe that the Earth rotates on its axis and that the fixed stars are not all the same distance from the Earth, and believed that the planets are held in their orbits by magnetism.
