51406 Massimocalvani           Discovered 2001 Feb. 26 by the Asiago-DLR Asteroid Survey at Cima Ekar.
Massimo Calvani (b. 1947) was director of the Astronomical Observatory of Padua and Asiago from 1999 to 2005, when the Asiago-DLR Asteroid Survey was carried out with the Schmidt telescope at Cima Ekar. His research is mainly on active galaxies, compact objects and relativistic astrophysics.
