‘Galvani: An electric current is produced when an animal tissue comes into contact with two different metals.
Volta: An electric current is not dependent on an animal tissue and can be produced by chemicals’
Galvani was wrong and Volta was right.
Galvani had found that by touching a dead frog’s legs with two different metal implements, the muscles in the frog’s legs would twitch. Galvani wrongly concluded it was the animal tissue that was storing the electricity, releasing it when touched by the metals. He felt he had discovered the very force of life – ‘animal electricity’ – that animated flesh and bone.
Soon dozens of scientists were trying to bring corpses back to life by electrifying them. Volta was not convinced the animal muscle was the important factor in the production of the current.
He repeated Galvani’s experiments and concluded, controversially at the time, the different metals were the important factor.
A bitter dispute arose as to whose interpretation was correct. Volta began putting together different combinations of metals to…
