Jacques-Arsene d"Arsonval (1851-1940) was a French physician and physicist best known for his pioneering work in electrotherapy. He studied the medical uses of high frequency currents. In 1882 he developed the d'Arsonval galvanometer which became the standard for all panel type pointer meters used to measure weak electric currents. "Brown-Séquard's investigation of spinal cord transection in which he defines the relative function of the posterior and anterior cord sections and their relationship to other neural pathways is one of his foremost accompishments and is explained fully in this impressive series of lectures" (Heirs of Hippocrates 1841).
