Rizzetti, Giovanni, 1675-1751 (natural philosopher)
- Existence: 1675 - 1751
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.

The Portsmouth Collection is the principal collection of Isaac Newton's scientific and mathematical papers, including early drafts of the Principia, and his correspondence with Oldenburg, Halley Flamsteed and many of the other most prominent scientists of his day.
The volume contains a draft letter from Rizzetti to Christino Martinelli, c.1720, with a description of Newton's experiment leading to the discovery of the aberration of light, and Rizzetti's experiment contradicting Newton's results; and two diagrams on refraction (p.13), the 'Anatomical composition of the eye' and the 'Aberration in telescopes with different lenses'. There are references to Descartes, Huygens and Tschirnhaus.
