16450 Messerschmidt           Discovered 1989 Sept. 26 by E. W. Elst at the European Southern Observatory.
During 1719-1728 German naturalist Daniel Gottlieb Messerschmidt (1685-1735) was sent by Peter the Great on a expedition to Siberia. The first person to study systematically the "rumors" about "frozen" mammoths, he investigated thoroughly Siberian fauna and flora, as well as its mineralogy and geography.
