Guess who, while making a tasty bowl of frog broth for his wife, discovered that the leg of a dead frog will twitch when an electric current is applied to it? You’re right! Luigi Galvani was born this day in Bologna, Italy in 1737. Galvanism, a direct current of electricity produced by chemical action, was named for him. And he inspired a vast number of quack medical devices.
No word on how the broth came out, though.
