To galvanize

Origin

In the late 18th century, the Italian physician Luigi Galvani made a startling discovery: applying an electrical current to a dissected frog's leg caused it to twitch dramatically, as if momentarily reanimated. This phenomenon, which he termed "animal electricity," captivated the scientific world, even as others like Alessandro Volta offered alternative explanations. But the vivid image of lifeless tissue springing into action through an external stimulus was too powerful to remain confined to the laboratory. By the early 19th century, the term "galvanize" had entered common parlance. It became a potent metaphor for shocking or stimulating someone into sudden activity, for injecting energy and movement where there was previously stagnation, much like Galvani's current brought a frog's leg back to life.
