55733 Lepsius           Discovered 1986 Nov. 27 by F. Börngen at Tautenburg.
German Karl Richard Lepsius (1810-1884) studied the monuments, pyramids and mastabas of the Old Kingdom (c. 2686-c. 2160 BC) in Egypt and Sudan. He did much to catalogue archaeological remains and to establish a chronology for Egyptian history.
