175629 Lambertini           Discovered 2007 Sept. 19 by F. Tozzi and M. Graziani at Skylive Observatory.
Giovanni Lambertini (1916-1997) was an Italian friar and enthusiast of science who taught physics and astronomy to many children. One of the founders of the group of amateur astronomers in Ravenna, he developed a passion for astronomy in many young people, and this minor planet has been discovered by two of them.
