Charles Augustin Coulomb

Angouléme (Charente)  11.6.1736-Paris 23.8.1806


Biographical notes

The father,   an official of the become army then tax-collector of the taxes,    had hoped  that   Charles became  doctor,  but  had an economic financial ruin, and the son entered in the military school of  engineering of Mézières. He then passed nine years in  the Martinica,  dedicating itself  to the reconstruction of the forts destroyed from the war of the seven years.  He returned in France to the age of 36 years in health conditions bad. In 1777  he gives to the press a memory on the method better than construction of the magnetic  needles, where he asserts  that  the magnetic  phenomena  can  be explain you single making reference  the same forces  that  regulate the gravity of the bodies and celestial physics. In 1779 he participated to a competition announced publicly  from the academy   slow combustion stove  on  the study  of   the magnetic variations,  which he allowed  it  to enter  in the academy and    were dedicated to the invention and    the study of the balance to torsion,    the most sensitive  instrument   (millionth of gram), than allowed to a deepening on the relationship between electricity and magnetism it.  With this he places the premises for the determination of the fundamental  law,   still today famous like  "Coulomb's law"   that he defines exactly loads with a body.

In 1789,  to  the explosion  of the French revolution,   of which  Coulomb he did not share the ideals,  one discharges from all its official assignments (in the meantime has caught up the lieutenant degree colonel of the Corps of Engineers), and  he withdraws himself to private life;  Napoleon,   then, in   1805, a year before its dead women, the nomination  General Inspector of the Studies.

In its honor the joined one was dedicated to it of loads electrical worker-Coulomb - (C)-.
