Luigi Galvani (/ɡælˈvɑːni/ gal-VAH-nee, US also /ɡɑːl-/ gahl-, 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, using a frog, he discovered that the muscles of dead frogs' legs twitched when struck by an electrical spark. This was an early study of bioelectricity, following experiments by John Walsh and Hugh Williamson.

👉 Luigi Galvani in the context of Victor Frankenstein
Victor Frankenstein, whose character name has sometimes evolved in popular culture to Dr. Frankenstein, is a fictional character who first appeared as the titular main protagonist of Mary Shelley's 1818 novel Frankenstein; or, The Modern Prometheus. He is a young Italian-born Swiss scientist who, after studying chemical processes and the decay of living things at university, gains an insight into the creation of life and gives life to his own creature (often referred to as Frankenstein's monster, or often colloquially referred to as simply "Frankenstein"). Victor later regrets meddling with nature through his creation, as he inadvertently endangers his own life and the lives of his family and friends when the creature seeks revenge against him. He is first introduced in the novel when he is seeking to catch the monster near the North Pole and is saved from potential fatality by Robert Walton and his crew.
Some aspects of the character are believed to have been inspired by 17th-century alchemist Johann Konrad Dippel. Certainly, the author and people in her environment were aware of the experiment on electricity and dead tissues by Luigi Galvani and his nephew Giovanni Aldini and the work of Alessandro Volta at the University of Pavia.

Luigi Galvani in the context of Guillaume Duchenne de Boulogne
Guillaume-Benjamin-Amand Duchenne (de Boulogne) (September 17, 1806, in Boulogne-sur-Mer – September 15, 1875, in Paris) was a French neurologist who revived Luigi Galvani's research and greatly advanced the science of electrophysiology. The era of modern neurology developed from Duchenne's understanding of neural pathways and his diagnostic innovations including deep tissue biopsy, nerve conduction tests (NCS), and clinical photography. This extraordinary range of activities (mostly in the Salpêtrière) was achieved against the background of a troubled personal life and a generally indifferent medical and scientific establishment.
Neurology did not exist in France before Duchenne and although many medical historians regard Jean-Martin Charcot as the father of the discipline, Charcot owed much to Duchenne, often acknowledging him as "mon maître en neurologie" (my master in neurology). The American neurologist Joseph Collins (1866–1950) wrote that Duchenne found neurology "a sprawling infant of unknown parentage which he succored to a lusty youth."His greatest contributions were made in the myopathies that came to immortalize his name, Duchenne muscular dystrophy, Duchenne-Aran spinal muscular atrophy, Duchenne-Erb paralysis, Duchenne's disease (Tabes dorsalis), and Duchenne's paralysis (progressive bulbar palsy). He was the first clinician to practise muscle biopsy, with an invention he called "l'emporte-pièce" (Duchenne's trocar). In 1855, he formalized the diagnostic principles of electrophysiology and introduced electrotherapy in a textbook titled De l'electrisation localisée et de son application à la physiologie, à la pathologie et à la thérapeutique. A companion atlas to this work, the Album de photographies pathologiques, was the first neurology text illustrated by photographs. Duchenne's monograph, the Mécanisme de la physionomie humaine – also illustrated prominently by his photographs – was the first study on the physiology of emotion and was highly influential on Darwin's work on human evolution and emotional expression.
Luigi Galvani in the context of Galvanism
Galvanism is a term coined by the late 18th-century physicist and chemist Alessandro Volta to refer to the generation of electric current by chemical action. The term also came to refer to the discoveries of its namesake, Luigi Galvani, specifically the generation of electric current within biological organisms and the contraction/convulsion of biological muscle tissue upon contact with electric current. While Volta theorized and later demonstrated the phenomenon of his "Galvanism" to be replicable with otherwise inert materials, Galvani thought his discovery to be a confirmation of the existence of "animal electricity," a vital force which gave life to organic matter.
Luigi Galvani in the context of Galvanic corrosion
Galvanic corrosion (also called bimetallic corrosion or dissimilar metal corrosion) is an electrochemical process in which one metal corrodes preferentially when it is in electrical contact with another, different metal, when both in the presence of an electrolyte. A similar galvanic reaction is exploited in single-use battery cells to generate a useful electrical voltage to power portable devices. This phenomenon is named after Italian physician Luigi Galvani (1737–1798).
A similar type of corrosion caused by the presence of an external electric current is called electrolytic corrosion.
