Short Summary
Charles-Augustin de Coulomb was a prominent French physicist best known for his work in electrostatics and magnetism. His formulation of Coulomb's Law, which describes the force between two electric charges, is a cornerstone of electromagnetism. Coulomb's contributions to physics and engineering have left a lasting impact on these fields, and his name is commemorated in the unit of electric charge, the coulomb. His work laid the groundwork for future scientists and helped to advance the understanding of electrical forces and phenomena.
Early Life & Education
Born on June 14, 1736, in Angoulême, France, Charles-Augustin de Coulomb was the son of a civil servant. His family moved to Paris when he was young, where he received an education at the Collège Mazarin. He later enrolled at the École Royale du Génie de Mézières, a prestigious engineering school, where he developed an interest in mathematics and physics. His early exposure to the sciences and engineering significantly influenced his future career. After graduating in 1761, he joined the French military engineering corps, which provided him with opportunities to apply his scientific knowledge practically.
Career Highlights
During his career, Coulomb served as a military engineer in various locations, including the West Indies, where he worked on fortifications. His interest in physics led him to conduct experiments on friction, elasticity, and torsion, which were critical to understanding mechanical behavior. In 1785, he presented a series of papers to the French Academy of Sciences, detailing his findings on electrical forces and magnetism. His work on electrostatics, particularly the formulation of Coulomb's Law, was groundbreaking. After the French Revolution, he retired from military service but continued his scientific research and became a member of the Bureau des Longitudes.
