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.Naming citation (20030806/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
