Charles Le Roy
Charles Le Roy (born June 12, 1726 in Paris , † December 10 (according to other sources on December 12 ) 1779 ibid) was a French doctor and encyclopedist . He was advisor to the king, professor of medicine at the University of Montpellier , member of the Académie des sciences , the Royal Society , the Société royale de médecine and the academies of Montpellier , Nîmes and Toulouse .
Life
Le Roy was born as the last of the four sons of the French watchmaker Julien Le Roy (1686–1759). He had three brothers: the watchmaker Pierre Le Roy (1717–1785), the physicist Jean-Baptiste Le Roy (1720–1800) and the architect Julien-David Le Roy (1724–1803). His paternal uncle Pierre Le Roy (1687–1762) was also a watchmaker. His father gave him an excellent education. Because he was weak and fragile, the young Le Roy was sent to the Mediterranean Montpellier, where he began a medical degree, which he continued in Italy. From there he went to Paris. But soon he was forced to move back to Montpellier for health reasons.
He received his doctorate in 1752 at the local medical faculty and soon afterwards became a professor. His teaching work received a lot of attention because of its thoroughness and accuracy. He had extensive experience and it was a great loss to Montpellier when he returned to Paris in 1777 at the urging of his family. But the return did not suit him, so that he died two years later.
Services
In 1755, Le Roy tried to cure a patient's blindness by sending pulses of electrical current through a wire wound around his head. The blind man saw vivid flashes of light but could not be healed. This is considered to be the first experimental evidence that nerves can be electrically stimulated , 36 years before Galvani described electrophysiological phenomena .
