24794 Kurland           Discovered 1993 Oct. 20 by E. W. Elst at the European Southern Observatory.
Kurland (Courland) is the ancient name of the districts Zemgale and Kurzeme in present-day Latvia. Ruled from 1201-1561 by German Knightly Orders, from 1562 to 1795 Kurland was linked to Poland. During the eighteenth century the country was dominated by skilled Jewish workers, artisans and a core of intelligentsia.
