Grimaldi, Francesco Maria (1618–1663)
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.
