Grimaldi, Francesco Maria (1618–1663)

Francesco Grimaldi

Francesco Grimaldi was an Italian Jesuit physicist and astronomer who was the first to describe the diffraction of light (in a work published posthumously in 1665) and the first to attempt a wave theory of light. He verified Galileo's law of the uniform acceleration of falling bodies, drew a detailed map of the Moon, and began the practice of naming lunar features after astronomers and physicists.
