When electronics was young - part 2:

Count Alessandro Giuseppe Anastasio Volta (1745–1827) belonged to an aristocratic family and was Professor of Physics at the universities of Como and Pavia. He became interested in a phenomenon described by Galvani in 1786 to the effect that “an electric spark, or contact with copper and iron, causes a frog’s leg to twitch”. This gave rise to the, fortunately short-termed, belief that animal tissue was necessary for the generation of electricity.
