Jacques-Arsène d'Arsonval (June 8, 1851 – December 31, 1940) was a French physician, physicist, and inventor of the moving-coil D'Arsonval galvanometer and the thermocouple ammeter. D'Arsonval was an important contributor to the emerging field of electrophysiology, the study of the effects of electricity on biological organisms, in the nineteenth century.
D'Arsonval was born in the Château de la Borie, in La Porcherie, Haute Vienne, France. He studied medicine in Limoges and Paris and obtained his medical degree in 1877. In 1892, he became director of the new laboratory of biophysics at the College de France and in 1894 was appointed professor.
d'Arsonval has a phenomenon named after him. An alternating current having a frequency of 10 kilohertz or greater produces no muscular contractions and does not affect the sensory nerves. It is also called the Tesla Current.
