Vincentio Reinieri

Vincenzo Renieri (* March 30, 1606 in Genoa, † November 5, 1647, also Vincentio or Vincenzio, also Reinieri or Reiner ) was an Italian mathematician and astronomer. He was a friend and student of Galileo Galilei.

Renieri was a member of Olive Taner, who sent him to Rome in 1623. From 1636 he taught privately mathematics and astronomy in Genoa, where the patrician son Daniele Spinola was one of his students. Renieri met Galilei after the process in 1633 in Siena, and later in his home in Arcetri, near Florence, where he was under house arrest. He became his followers and was also a friend of the Galilean disciples Vincenzo Viviani. On behalf of Galileo improved the astronomical tables of Jupiter's moons based on our own observations. Galileo left behind him all his own observations and calculations to at his death. Reineri 1639 published tables of Jupiter's moons. The prediction of the motion of Jupiter's moons had ( as Galileo found ) potential applications to one of the greatest unsolved problems of that time, the determination of longitude at sea ( see linear problem). Most of his posthumous records and letters disappeared soon after his death, including those of Galileo, who were in his possession ( they were stolen ).

Renieri was professor of mathematics at the University of Pisa as a successor of Dino Peri. He also taught Greek. His own successor was Famiano Michelini.

According to him, the moon crater Reiner and Reiner Gamma is named on the moon.
