named for a man who made dead frog legs twitch, now it means inspiring crowds.
means Stirring people into sudden, energized action — or, literally, coating iron or steel with zinc to protect it from rust.
from From the name of Luigi Galvani, an 18th-century Italian physician and physicist who discovered that an electric spark made the legs of dead frogs twitch — what he called 'animal electricity.' His name gave us 'galvanism' for electrical stimulation, then 'galvanize,' which split two ways: the literal industrial sense of zinc-coating metal by electrical process, and the figurative sense of jolting a crowd into life as if zapped with current.
