Galvani was born, educated and taught anatomy in Bologna. The Italian physiologist made one of the early discoveries that advanced the study of electricity. His work with frogs led to his discovery in 1781 of galvanic or voltaic electricity. Galvani found he could make the muscles of a dead frog twitch when he touched them with different metals or the current from a nearby static electric generator. But he incorrectly thought fluid in the frog's body was the source of the electricity. This discovery soon led to another by Allesandro Volta, who invented the electric cell or early battery.
By 1800, Volta proved that the source of the electricity was a reaction caused by the animal's body fluids being touched by two different types of metal.
