Willaim Gilbert lived during the time of Shakespeare and was one of Queen Elisabeth I doctors. Gilbert was interested in many things, such as magnetism, and felt that this mysterious force could possibly heal the body.

Gilbert was not like the other so-called philosophers of his time who would formulate a theory on so in so but felt it was beneath them to build or carry out experiments. Gilbert, however, got his hands dirty and carried out careful lab tests. He determined many substances could conduct and some that would not. He concluded that it wasn’t the heat from rubbing amber that attracted things like straw but a force that he called electricus.
