Borngen and L. D. Schmadel at Tautenburg. Charles-Augustin de Coulomb (1736-1806) was one of the most famous physicists of his time. Best known for the law, force and unit of charge that are named for him, he published his findings in the seven fundamental treatises Sur l´électricité et le magnétisme.
