It consists of a skinned frog's leg with electrical connections to a nerve. The instrument was invented by Luigi Galvani and improved by Carlo Matteucci. The frog galvanoscope, and other experiments with frogs, played a part in the dispute between Galvani and Alessandro Volta over the nature of electricity.
Galvani's Frog's Leg Experiment. A chance observation led Luigi Galvani (1737-98) to discover animal electricity in 1771. The IET Archives holds two rare editions of Galvani's work `De Viribus- Electricitatis in Motu Musculari' from 1791 and 1792.
Luigi Galvani (/ ɡ æ l ˈ v ɑː n i /, also US: / ɡ ɑː l-/; Italian: [luˈiːdʒi ɡalˈvaːni]; Latin: Aloysius Galvanus; 9 September 1737 – 4 December 1798) was an Italian physician, physicist, biologist and philosopher, who studied animal electricity. In 1780, he discovered that the muscles of dead frogs' legs twitched when struck by ...

During an electrical experiment, Italian physician and anatomist Luigi Galvani watched as a scalpel touched a dissected frog on a metal mount — and the frog’s leg kicked. Further experiments led him to theorize that living bodies contain an innate vital force that he called “animal electricity.”
In the 1780s, the Bolognese physician Luigi Galvani (1737-1798) conducted a vast range of experiments on electricity's effect on "prepared" frog specimens - that is, frog legs severed at the base of the spine, with nerves exposed.
Sep 7, 2017 · Galvani was deeply surprised by the frog “jumping” and did a series of bizarre and macabre experiments, like frogs in a jar and frogs in a circle to determine what would make the frog dance. He also moved on to other animals and found that all animals would display this behavior to some extent.
Sep 15, 2015 · One day in 1786, Galvani was researching a dissected frog in his laboratory as an electrical storm raged outside. To his surprise, the frog’s leg muscle twitched whenever his scissors touched a nerve. This made him wonder if, through the air, the lightning could have exerted some subtle influence on the frog’s nerves and muscles.
