13111 Papacosmas           Discovered 1993 July 23 by C. S. Shoemaker and D. H. Levy at Palomar.
Constantine Papacosmas (b. 1939) an accomplished amateur astronomer in Montreal has guided thousands of people to learn the night sky. The telescopes he has constructed are among the finest in Canada, including a refractor that won an award at Stellafane in 1979.
