Rizzetti, Giovanni

Giovanni Rizzetti (1675-1751), Italian scientist, was a fierce critic of Sir Isaac Newton's optical theories. While the French edition of Newton's Opticks was in preparation, Rizzetti challenged some of Newton's experiments, his interpretation of them, and his theory of colours. Rizzetti repeated his challenge in a letter to Christino [sic] Martinelli. Newton suspected that an opponent, Antonio Schinella Conti had instigated Rizzetti's challenge.
