Nascido no Castelo de la Borie, la Por\u00adche\u00adrie, na regi\u00e3o da Aqui\u00adt\u00e2\u00adnia, em 8 de junho de 1851, Jacques \u2011Ars\u00e8ne d\u2019Arsonval ini\u00adci\u00adal\u00admente estudou medi\u00adcina, pri\u00admei\u00adra\u00admente no Liceu Imp\u00e8\u00adrial de Limoges (atual Liceu Gay-Lussac) e depois no Coll\u00e8ge Saint Barbe, Paris, for\u00admando-se em 1877. Na capital fran\u00adcesa passou a ter contato com impor\u00adtan\u00adtes pes\u00adqui\u00adsa\u00addo\u00adres da \u00e9poca, tais quais Claude Bernard (famoso fisi\u00f3\u00adlogo, alcu\u00adnhado por Bernard Cohen de \u201cum dos maiores homens da Ci\u00eancia\u201d) e Charles-\u00c9douard Brown-S\u00e9quard (reno\u00admado neurologista).
\nInflu\u00aden\u00adci\u00adado pelo tra\u00adba\u00adlho de Bernard, d\u2019Arsonval decidiu largar uma pro\u00admis\u00adsora car\u00adreira na medi\u00adcina para devotar sua vida \u00e0 pes\u00adquisa cien\u00adt\u00ed\u00adfica. Dirigiu, de 1882 a 1910, o labo\u00adra\u00adt\u00f3\u00adrio de Bio\u00adf\u00ed\u00adsica do Coll\u00e8ge de France e, pos\u00adte\u00adri\u00ador\u00admente, o novo labo\u00adra\u00adt\u00f3\u00adrio em Nogent-sur-Marne, at\u00e9 1931.
\n \tDes\u00adta\u00adcou-se pelas grandes con\u00adtri\u00adbui\u00ad\u00e7\u00f5es no campo da Ele\u00adtro\u00adfi\u00adsi\u00ado\u00adlo\u00adgia, rea\u00adli\u00adzando in\u00fa\u00adme\u00adras des\u00adco\u00adber\u00adtas rela\u00adti\u00advas ao uso de ele\u00adtri\u00adci\u00addade para fins medi\u00adci\u00adnais. Nessa linha de pes\u00adquisa, desen\u00advol\u00adveu, em par\u00adce\u00adria com Marcel Depr\u00e8z, o Gal\u00advan\u00f4\u00adme\u00adtro de d\u2019Arsonval, para detec\u00ad\u00e7\u00e3o de cor\u00adren\u00adtes t\u00eanues.

\n \tSeus estudos con\u00adtem\u00adpla\u00adram uma vasta gama de efeitos fisi\u00ado\u00adl\u00f3\u00adgi\u00adcos pro\u00advi\u00addos de cor\u00adren\u00adtes alter\u00adnada, campos el\u00e9\u00adtri\u00adcos e mag\u00adn\u00e9\u00adti\u00adcos vari\u00e1\u00adveis no tempo, cor\u00adren\u00adtes indu\u00adzi\u00addas atrav\u00e9s de aco\u00adpla\u00admento indu\u00adtivo ou capa\u00adci\u00adtivo bem como altas frequ\u00ean\u00adcias. Por falar em cor\u00adrente alter\u00adnada, Tesla ficou muito feliz ao saber que d\u2019Arsonval uti\u00adli\u00adzava seus osci\u00adla\u00addo\u00adres para inves\u00adti\u00adgar os efeitos fisi\u00ado\u00adl\u00f3\u00adgi\u00adcos de cor\u00adrente de alta frequ\u00ean\u00adcia; o epi\u00ads\u00f3\u00addio ocorreu numa visita do cien\u00adtista aus\u00adtr\u00edaco, mas na \u00e9poca j\u00e1 natu\u00adra\u00adli\u00adzado ame\u00adri\u00adcano, a Paris, em 1892.\t No mesmo ano, d\u2019Arsonval intro\u00addu\u00adziu o uso de cor\u00adren\u00adtes de alta frequ\u00ean\u00adcia para tratar doen\u00e7as de pele e mem\u00adbra\u00adnas mucosas, conhe\u00adci\u00addas atu\u00adal\u00admente como Cor\u00adren\u00adtes de d\u2019Arsonval; tamb\u00e9m demos\u00adtrou como o corpo humano pode supor\u00adtar uma cor\u00adrente alter\u00adnada forte o sufi\u00adci\u00adente para acender uma l\u00e2mpada.
\n \tTendo sido pro\u00adl\u00ed\u00adfico em in\u00fa\u00adme\u00adras \u00e1reas do conhe\u00adci\u00admento, era um membro ativo de soci\u00ade\u00adda\u00addes de ele\u00adtro\u00adte\u00adra\u00adpia, f\u00edsica ele\u00adtr\u00f4\u00adnica, enge\u00adnha\u00adria, ele\u00adtro\u00adce\u00adr\u00e2\u00admica e sol\u00adda\u00adgem, bem como membro da Soci\u00ade\u00addade dos Bi\u00f3\u00adlo\u00adgos, Aca\u00adde\u00admia de Medi\u00adcina e Aca\u00adde\u00admia de Ci\u00ean\u00adcias.
