20256 Adolfneckař           Discovered 1998 Mar. 23 by P. Pravec at Ondřejov.
Adolf Neckař (1909-1995) built a public observatory in Prostějov, Moravia, from 1950 at a provisional site on the roof of the local school building and from 1961 in a separate building. He was the observatory's director until 1971. His main focus was drawing and photographing the planets.
