- Léon Charles Thévenin
Léon Charles Thévenin (
March 30 ,1857 -September 21 ,1926 ) was a Frenchtelegraph engineer who extendedOhm's law to the analysis of complex electrical circuits.Background
Born in
Meaux , Thévenin graduated from theÉcole Polytechnique inParis in 1876. In 1878, he joined the corps of telegraph Engineers (which subsequently became theFrench PTT ). There, he initially worked on the development of long distance underground telegraph lines.Appointed as a teaching inspector at the
École Supérieure in 1882, he became increasingly interested in the problems of measurement in electrical circuits. As a result of studyingKirchhoff's circuit laws and Ohm's law, he developed his famous theorem,Thévenin's theorem , which made it possible to calculate currents in more complex electrical circuits and allowing people to reduce complex circuits into simpler circuits called as Thévenin's equivalent circuit.Also, after becoming head of the
Bureau des Lignes , he found time for teaching other subjects outside the École Supérieure, including a course in mechanics at theInstitut National Agronomique , Paris. In 1896, he was appointed Director of the Telegraph Engineering School, and then in 1901, Engineer in chief of the telegraph workshops.See also
