“Who developed the lightning rod?”

"Benjamin Franklin a polymath of the 18th century invented the lightning rod a device that protects buildings from lightning strikes by directing electrical charges safely to the ground. His groundbreaking work in electricity including experiments with kites established foundational principles of electrical conductivity. The lightning rod remains a critical safety feature in modern architecture preventing fire hazards and structural damage. Franklin’s invention underscores his legacy as a scientist and innovator contributing significantly to the understanding of electricity and its practical applications in everyday life."
