The Discovery of Animal Electricity
In the late 1780s, Italian doctor Luigi Galvani discovered that animal muscles could be made to contract when exposed to an electrical circuit. This led to the hypothesis of animal electricity, the idea that animals store electricity in their cells like a battery. Galvani's findings were later questioned by Alessandro Volta, who determined that the contraction of muscles was caused by a circuit between different metals, creating an electrical current. Volta's experiments ultimately led to the invention of the battery.
