image:Francescomaria_Grimaldi.jpgFrancesco Maria Grimaldi (April 2, 1618 - December 28, 1663) was an Italy mathematician and physicist who taught at the Jesuit college in Bologna.

Between 1640 and 1650, working with Giovanni Riccioli, he investigated the free fall of objects, confirming that the distance of fall was proportional to the square of the time taken.

In astronomy, he built and used instruments to measure geological features on the Moon, and drew an accurate map or selenograph which was published by Riccioli.

He was the first to make accurate observations on the diffraction of light (although by some accounts Leonardo da Vinci had earlier noted itGuglielmo Libri, Histoire des sciences mathematiques en Italie (1840) ), and coined the word 'diffraction'. Later physicists used his work as evidence that light was a wave, and Isaac Newton used it to arrive at his more comprehensive theory of light.

Grimaldi (crater) on the Moon was named after him.
