Frog Legs to the Battery: How Galvani and Volta Invented Electricity

In 1780, a Bolognese anatomist named Luigi Galvani noticed that dead frog legs hanging on a brass hook by an iron railing would twitch when the wind blew. He believed animals contained their own secret electricity. A few years later, a Pavian physicist named Alessandro Volta proved him wrong - mostly - and in trying to prove it, invented the 1st battery in 1800. The age of electricity begins with an argument over what makes a dead frog twitch. This is Episode 11 of The Great Discoveries: How Science Built the Modern World.
