Luigi Galvani was a physician, and unlike many other fathers of electrical technology, often found himself more interested in the ream of biology and anatomy than that of electricity and physics. nonetheless, in 1783, Galvani noticed that touching two dissimilar metals to specific points on the leg of a frog (discovered later to be exposed nerve endings), the leg kicked as if alive.
What Galvani noticed was an electrochemical reaction. the scalpel he was using had apparently picked up a static charge, which was transferred to the frog's nerve and from there to the muscles. The muscles, when exposed to a current, contract, thus making the leg kick.
Though Galvani did not know it at the time, his simple kicking frog leg demonstrated the existence of bio-electricity. For this, his name is given to the phenomena he noticed: the contraction of muscles when exposed to an electric current (what Galvani called animal electricity) is now known as Galvanism.
