Niccolò Zucchi 
Niccolò ZucchiBorn December 6, 1586 Died May 21, 1670 Nationality Italian Fields astronomer Known for concave reflecting telescope Niccolò Zucchi (December 6, 1586 – May 21, 1670) was an Italian Jesuit, astronomer, and physicist.
As an astronomer he may have been the first to see the belts on the planet Jupiter (on May 17, 1630),[1] and reported spots on Mars in 1640.
He published his book "Optica philosophia experimentalis et ratione a fundamentis constituta" in 1652–56 in which he described his attempt in 1616 to construct a reflecting telescope, which may be the first time anyone ever tried to construct one. In his book he also demonstrated that phosphors generate rather than store light. He also published two other works on mechanics and machines.

Biography
Niccolò Zucchi was fourth of eight children born into the noble family of Pierre Zucchi and Francoise Giande Marie. Three of his sisters became nuns, three of his brothers became Jesuits, and one brother became a secular priest.
The Jesuit order
Niccolò studied rhetoric in Piacenza and philosophy and theology in Parma. He finished his studies at the age of sixteen and entered the Jesuit order in Padua on October 28, 1602, in which he remained for the rest of his life.
Zucchi taught mathematics, rhetorics and theology as a professor at the Collegio Romano, and then was appointed as rector of a new Jesuit college in Ravenna by Cardinal Alessandro Orsini. He later served as the apostolic preacher, a post often referred to as “preacher to the pope”, for about seven years. He received patronage from Ranuccio II Farnese, Duke of Parma, to which Zucchi dedicated his book Nova de machinis philosophia in 1642. He also dedicated his 1652 book Optica philosophia, to Archduke Leopold of Austria. Near the end of his life, he was an official of the Jesuit house in Rome. Zucchi died in Rome on May 21, 1670.
Scientist
Niccolò Zucchi published many books on science, including two works on the philosophy of machines (analyses of mechanics) in 1646 and 1649, and Optica philosophica in 1652. He also wrote an unpublished Optica statica, which has not survived. Some of the subjects Zucchi wrote about were magnetism, barometers (denying the existence of the vacuum), and demonstrated that phosphors generate rather than store light. He also asserted that since Venus represented beauty, it was closer to the Sun than Mercury (which represented skill).
Astronomer
In 1632, Zucchi was a member of a Papal legate sent to the court of Ferdinand II. There he met Johannes Kepler, the German mathematician and astronomer.
Kepler encouraged Zucchi’s interest in astronomy. Zucchi maintained correspondence with Kepler after returning to Rome. At one point when Kepler was in financial difficulties, Zucchi, at the urging of the Jesuit scientist Father Paul Guldin, gave a telescope of his own design to Kepler, who mentioned the gift in his book “The Dream”.[2]
Zucchi along with fellow Jesuit Daniello Bartoli may have been the first to see the belts on the planet Jupiter on May 17, 1630,[3][4] and Zucchi reported spots on Mars in 1640. The crater Zucchius on the Moon is named in Niccolò Zucchi's honor.
Zucchi's mirror telescope
One of the things cited by Zucchi in his 1652 book "Optica philosophia experimentalis et ratione a fundamentis constituta" is his description of trying to make what may have been the first reflecting telescope, in 1616. Zucchi described how he tried replacing the lens of a refracting telescope with a borrowed bronze parabolic mirror. Zucchi tried looking into the mirror with a hand held concave lens but did not get a satisfactory image, possibly due to the poor quality of the mirror, the angle it was tilted at, or the fact that his head partially obstructed the image.[5] He apparently abandoned the idea and went back to using refracting telescopes.[6]
