Coulomb was a Roman Catholic.
Coulomb was born in Angoulême, France in 1736. His family moved to Paris. Coulomb studied mathematics there. In 1759 he went to military school and was stationed in many places like Martinique. 1773 Coulomb returned to France. He made contributions in a great many areas of physics, such as elasticity. But he is best known for his research in electricity, in the late 1780's, particularly the law of electrostatic attraction and repulsion known as Coulomb's Law.
The standard unit of electric charge, the coulomb is named in his honor.
