20103 de Vico           Discovered 1995 May 6 by R. Calanca at Cavezzo.
The Jesuit Francesco de Vico (1805-1848), best known as the discoverer of seven comets, including 54P and 122P, was director of the Observatory of Collegio Romano in Rome from 1838 to 1848. De Vico was born in the city of Macerata, and the Osservatorio di Monte D´Aria di Serrapetrona is dedicated to him.
