52301 Qumran           Discovered 1991 Sept. 9 by F. Börngen and L. D. Schmadel at Tautenburg.
Qumran, situated on the shore of Dead Sea, is the region where numerous Scrolls, 2000 years old, were discovered in caves. Owners of these notable scripts were members of the Qumran community of Essenes. The ruins of their buildings were excavated beginning in 1949.
