16930 Respighi           Discovered 1998 Mar. 29 at Osservatorio San Vittore.
Italian astronomer Lorenzo Respighi (1824-1889) was professor of optics and astronomy and director successively of the observatories of Bologna and of Campidoglio in Rome. He compiled stellar catalogues, observed the planets and discovered three comets. He introduced the use of the objective prism in stellar spectroscopy.
