Vincentio Reinieri

Vincentio (Vincenzio, Vincenzo) Reinieri (Renieri, Reiner) (30 March 1606 – 5 November 1647) was an Italian mathematician and astronomer.

On 5 February 1641 Reinieri wrote to Galileo from Pisa: "Not infrequently I am in some battle with the Peripatetic gentlemen, particularly when I note that those fattest with ignorance least appreciate your worth, and I have just given the head of one of those a good scrubbing."

(Drake, p. 413-4) Reinieri became professor of mathematics at the University of Pisa on the death of Dino Peri.

Reinieri's observations of Jupiter's moons remained unpublished at the time of his premature death at Pisa in 1647.

On Reinieri's death, papers concerning longitude entrusted to him by Galileo are said to have been stolen by a man named Giuseppe Agostini (Fahie, p. 374).
