Djedefre
From SJS Wiki
Djedefre was the son of the Pharaoh Khufu; he ruled during Egypt's fourth dynasty. He built his pyramid at Abu Rawash so he could be closer to the cult center of Ra, and he was the first Pharaoh to call himself the "son of Ra." Djedefre was the pharaoh who constructed the Sphinx at Giza.
