History
In 1780, Luigi Galvani discovered that when two different metals (e.g., copper and zinc) are connected and then both touched at the same time to two different parts of a nerve of a frog leg, then the leg contracts. He called this "animal electricity". The voltaic pile, invented by Alessandro Volta in the 1800s, is similar to the galvanic cell.
These discoveries paved the way for electrical batteries; Volta's cell was named an IEEE Milestone in 1999.
