What does galvanism mean?
Galvanism refers to electricity produced by chemical action — essentially, the direct current that flows from a battery or electrochemical cell — as well as the older medical practice of applying such currents to living tissue, famously demonstrated by making the muscles of dead animals contract. Named after the Italian physiologist Luigi Galvani, who discovered in the late eighteenth century that dissected frog legs twitched when touched with metal instruments, the term became central to debates about the nature of 'animal electricity'. In the Romantic era, public demonstrations of galvanism carried an almost supernatural fascination, and they directly influenced Mary Shelley's Frankenstein. Today galvanism is chiefly encountered in historical, literary, and scientific contexts, evoking the dawn of electrical science and the enduring question of where life ends and physics begins.
Electricity produced by chemical action, especially direct current from a battery or voltaic cell.
"The apparatus supplied steady galvanism to the circuit."
In scientific usage this sense has been superseded by terms like 'direct current', leaving galvanism mostly historical.
The application of electric current to the body, historically to stimulate nerves and muscles therapeutically.
"Nineteenth-century sanatoriums offered courses of galvanism for patients suffering paralysis."
Now encountered mainly in accounts of historical medicine and literature.
Rarely pluralized; galvanism is nearly always used as an uncountable mass noun referring to the phenomenon or treatment generally.
"Early experimenters recorded various galvanisms in their notebooks, though few writers ever use the plural."
Mary Shelley wrote Frankenstein after hearing discussions of galvanism — the eerie science of making dead tissue twitch with electricity.

Etymology of galvanism
Galvanism takes its name from Luigi Galvani (1737–1798), the Italian physician who observed that dissected frog legs convulsed when touched by paired metal implements, which he attributed to 'animal electricity'. His contemporary Alessandro Volta later showed the effect arose from the metals themselves, leading to the voltaic pile and modern batteries — so the word honours Galvani even though Volta explained the phenomenon. Derived forms such as galvanic, galvanize, and galvanometer all trace back to the same eponym.

How galvanism is actually used
Galvanism is largely a historical and scientific term today; in modern contexts it sounds formal or antiquarian and appears mostly in discussions of science history, Romantic literature, and the early history of electrophysiology. The related adjective 'galvanic' remains more current.
Easily confused with galvanism
Galvanization is the industrial coating of metal (usually steel) with zinc to prevent rusting, whereas galvanism refers to electricity from chemical action or its therapeutic use — both derive from Luigi Galvani but denote entirely different processes.
