GALVANI’S DANCING FROG
In 1781, Italian surgeon Luigi Aloisio Galvani discovered what he called ‘animal electricity’, or bioelectricity, as it is known today. He observed that, when you touch a scalpel to a nerve in a dead frog’s leg, it will make the limb jump. He later found out that a spark of electricity has the same effect. He published his findings a decade later, by which time he developed a reputation for being able to make his deceased frogs dance.
