7450 Shilling           Discovered 1968 July 24 by G. A. Plyugin and Yu. A. Belyaev at Cerro El Roble.
Pavel L´vovich Shilling (1786-1837) was an outstanding Russian inventor and orientalist. In 1832 he became the first to invent an electromagnetic telegraph suitable for practical use. He investigated the history and languages of Asian peoples and gathered a large collection of oriental manuscripts.
