Luigi Galvani
Luigi Galvani in an illustration from Le Journal de la Jeunesse, Paris, 1880.
When Luigi Galvani touched a frogās nerves with a pair of scissors during an electrical storm in 1786, he observed the frog's muscles undergo contraction.
This observation was a pivotal moment in his investigation into electrophysiology. Galvani initially hypothesized that this movement was caused by an innate "animal electricity" present within the living tissue. While his specific interpretation of this force was later debated and refined by Alessandro Volta, Galvaniās experiments successfully demonstrated that electrical stimuli could trigger muscular motion, ultimately laying the groundwork for the study of bioelectricity and the development of the voltaic pile.1
