Charles-Augustin de Coulomb – The Author of Coulomb’s Law
Charles-Augustin de Coulomb (14 June 1736, Angoulême, Angoumois county, France -23 August 1806, Paris France) was a French military engineer, physicist and inventor. He is known for his contributions in the fields of physics that study electricity and magnetism, he studied friction in machines like windmills, elasticity of metal and silk fibers, viscosity, invented a torsion scale, discovered the law of twisting or torsion. The torsion bar measured the strength of the force between the electrically charged body and investigated its dependence on their mutual spacing and the amount of electrical charge on the body, which is called the Coulomb’s law.
Career and inventions by Charles-Augustin de Coulomb
Coulomb was born on June 14, 1736, in Anguleme, France. He comes from an aristocratic family that has provided him with the finest studies in Paris. Coulomb, being able to choose, decided to study mathematics. In 1759, he enrolled in a military school that he completed until 1761. Then he was employed as a construction engineer in Martinique. He suffered an accident in this business and received a serious injury. He decided to go to La Rochelle. There, Coulomb’s law came into being, by which Charles-Augustin de Coulomb defined the electrostatic force of attraction and rejection.
In 1781, Coulomb moved permanently to Paris. During this period, he wrote many important papers on various aspects of electricity and magnetism and won the prestigious award of the French Academy of Sciences. When the French Revolution began, Coulomb, like many aristocrats, was excluded from the government. In 1791, he retired to his estate in Blois and dedicated himself to scientific research there. In 1797, he had a son, but in 1802 he married a child’s mother.
After the revolution, Coulomb was called to Paris, on the orders of the Revolutionary Government, when he was supposed to attend a conference on which the units of measurement were determined. In 1802, Coulomb was appointed as an inspector of public instruction. In that period, he was sick of a fever that slowly took his life. August 23, 1806, Charles-Augustin de Coulon died.
Coulomb’s name has been carved into the history of mechanics and the magnetism of electricity. SI unit for electric charge coulons (C), and Coulomb’s law are named in his honor.
