The Galvanis experimenting on frogs
Luigi Galvani and his wife Lucia demonstrating contractions of the muscles of the leg of a frog caused by electrical stimulation. The phenomenon was first noticed when his assistant touched an exposed nerve of the frog with a metal scalpel just as an electrostatic generator was emitting sparks. Galvanis wife and collaborator Lucia Galvani Galeazzi assisted her husband in his work. It is said that she first observed this phenomenon whilst he was in another room and alerted him to this strange occurrence. Galvanis theory of animal electricity was disputed by Alessandro Volta who suggested the electricity was produced by the conjunction of two dissimilar metals

EDITORS COMMENTS
This print captures the groundbreaking moment when Luigi Galvani and his wife Lucia embarked on their pioneering experiments with frogs. In this image, we witness the mesmerizing contractions of a frog's leg muscles caused by electrical stimulation. The phenomenon was accidentally discovered when Galvani's assistant inadvertently touched an exposed nerve of the frog with a metal scalpel while an electrostatic generator emitted sparks. Lucia Galvani Galeazzi played a crucial role in her husband's scientific endeavors, acting as both collaborator and observer. It is said that she first observed this extraordinary occurrence while Luigi was in another room, promptly alerting him to its strangeness. Luigi Galvani proposed his theory of animal electricity based on these remarkable findings, suggesting that the electricity originated from the conjunction of two dissimilar metals within living organisms. However, his theories faced opposition from Alessandro Volta, who argued that the electricity produced was solely due to metal interactions. This iconic photograph not only showcases one of science's most significant discoveries but also highlights the collaborative efforts between Luigi and Lucia Galvani. Their work laid the foundation for galvanism and our understanding of electrical stimulation in biological systems. As we delve into this historical moment captured by Science Photo Library, we are reminded of how curiosity and serendipity can lead to groundbreaking scientific breakthroughs.
