Coulomb ¹ Scientific  

1. French physicist who was a pioneer in the study of magnetism and electricity. He is best known for the formulation of Coulomb's law, which he developed as a result of his investigations of Joseph Priestley's work on electrical repulsion. Coulomb also established a law governing the attraction and repulsion of magnetic poles. The coulomb unit of electric charge is named for him.
