Unfortunately Coulomb was not long spared to continue his work.
It is because of this pioneer work that Coulomb deserves so much praise.

Word Origin and History for coulomb
1881, named for French chemist Charles-Augustin de Coulomb (1736-1806), who devised a method of measuring electrical quantity. It is the quantity of electricity conveyed in 1 second by a current of 1 ampere. The name is a French form of Columbus.
- The unit of electrical charge in the meter-kilogram-second system equal to the quantity of charge transferred in one second by a steady current of one ampere.
- The SI derived unit used to measure electric charge. One coulomb is equal to the quantity of charge that passes through a cross-section of a conductor in one second, given a current of one ampere.
- 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.
