Luigi Galvani

Luigi Galvani (gal-VAH-nee, US also gahl-; Italian: [luˈiːdʒi ɡalˈvaːni]; Latin: Aloysius Galvanus; 9 September 1737 – 4 December 1798) was an Italian physician, physicist, biologist and philosopher who studied animal electricity. In 1780, using a frog, he discovered that the muscles of dead frogs' legs twitched when struck by an electrical spark. This was an early study of bioelectricity, following experiments by John Walsh and Hugh Williamson.
