19268 Morstadt           Discovered 1995 Oct. 21 by P. Pravec at Ondřejov.
Josef Morstadt (1797-1869) was a Czech astronomer, physicist and mathematician; he computed orbits of comets (notably of 3D/Biela) and was engaged in early meteor astronomy. His brother Vincenc (1802-1875) was a painter, known especially for his charming views, mainly of Prague.
